COMPARISONS (best viewed as images loaded to separate tabs)
- Turn off ubersampling (meant for supercomputers)
- Turn off bloom (meant for atomic/post nuclear wasteland simulation)

Stuttering? Try this.
General performance tweaking guide (detailed explanations / pictures of settings)
Suggested ini tweaks for 3D Vision
Stuck at a black screen or game not loading at all w/ Steam version? Close & exit steam and run it again as an administrator.
user.ini tweaking guide - further enhance settings, increase fps
Guide for gaming laptops
Common issues and possible solutions
Disc problems with retail? Try making isos. Or this, and/or also updating your drive's firmware (may fix CRC errors).
How to fix "Error Writing File" message from launcher
3GB switch fix for Vista 32/ Win7 32 (for those experiencing crashes to desktop)
Want a locked 30fps? Use DXtory, FPS Limiter or if you have an ATI card, use RadeonPro with double vsync option
Text too small to read on HDTVs? Try this.
No response from the gamepad or stuck/stalled and can't fight? Get hit in combat to fix.

Getting really weird fog-like visuals like above? Most likely you are forcing AA in your GPU's drivers, turn AA off in CCC/nVidia. Or maybe Catalyst AI is to blame.

- If you really want ubersampling, and have the hardware, turn off AA option (double-dips)
- Turning off the DOF makes such a HUGE difference to the frame rate.
- Turning off AA and/or motion blur can make a huge difference in some configurations
- Certain unknown graphic settings such as ground/road LOD are set by the preset you select, and cannot be other changed. See here.
- Nvidia owners should trying uninstalling 3D drivers & updating to latest drivers, may improve performance drastically (fixed in 1.3)
- How to get 5.1 sound working on 7.1 systems (for the G35). Alternate solution w/o removal of drivers.
- How to invert mouse (fixed in 1.1)
- How to invert the gamepad, if this doesn't work change it in the user.ini suggested above (fixed in 1.1)
- To fix the floaty mouse cursor, change Smoothness=1 to Smoothness=0 under the mouse settings in the User.ini​

SLI/XFIRE INFO (currently out of date, needs updating)
Patch 1.3 should improve things a little, be sure to try updating.
"(XFIRE) Performance has been fixed in 11.6b & 11.6 CAP1."
New AMD hotfix (8.85.6 RC5 - May 25) is out! Initial feedback is extremely good w/ xfire, some sparadic light issues, hopefully resolved soon.
New SLI info, no bleeding lights, examples of bleeding lights with SLI info
Working SLI profile, Use "0x02C04205," Additional info
Crossfire profile: both cards working @ 95% (use Radeon Pro), Additional info, update for flickering lights
If running crossfire, disable one of your GPUs for a performance increase until supported officially
Or see pahamrick's advice for using crossfire​

readme.txt said:
-Texture downscaling: higher values result in lower texture quality.
-Texture memory size: sets the amount of graphics card memory allocated to textures. Larger values will decrease the amount of streaming that occurs in game and will make the game run more smoothly, but they can also cause the graphics card to run out of memory and even result in game crashes. Choose a reasonable value based on the amount of memory available on your graphics card.
- Shadow quality: affects graphics performance. Consumes GPU power without affecting CPU performance.
- Number of shadowed lights: set the maximum number of lights that cast shadows. Affects graphics performance. Consumes GPU power without affecting CPU performance.
- LOD distance: distance scale for level of detail on meshes. Lower values improve game performance but result in reduced detail on models.
- Bloom: effect greatly improves quality of game graphics without placing excess demands on GPU.
- Light shafts: visual effect recommended for medium-high/high-end machines. Should be disabled on older systems.
- Anti-aliasing: demanding effect that can significantly reduce performance, so it should be disabled on medium and low-end machines.
- Blur effects: special blur and radial blur visual effects that are quite demanding on hardware but used rarely in the game.
- Depth of field – gameplay: subtle visual effect. Option determines appearance of effect only during gameplay sequences and does not affect DoF in cutscenes.
- Vignette: aesthetic option that produces a photographic vignette around the game screen. Does not affect performance.
- Rain, Wet surfaces rain effect: modest impact on performance.
- SSAO (Screen Space Ambient Occlusion): lighting effect that is important to the game but unfortunately places significant demands on the GPU.
- Motion blur: blur effect on camera movement, demanding on the GPU.
- Cinematic depth of field: provides movie-like depth of field in cutscenes and dialogue sequences. Extremely detailed but demands significant power. Should only be enabled on machines equipped with top-end graphics cards.
- Depth of field – cutscenes: option only affects cutscenes and dialogue sequences, does not affect gameplay performance.
- Dangling objects limit: limiter for physical animation of character components like Geralt's hair. Disabling this option places greater demands on the CPU.
- Ubersampling: high quality rendering mode under which whole scenes are rendered multiple times to provide the best possible textures, object details and anti-aliasing (superior to anti-alias and anisotropy even on the highest settings). Use with caution, only on top-end computers (best possible in terms of both GPU and CPU).
- Vertical sync: helps eliminate "screen tearing" (http://en.wikipedia.org/wiki/Screen_tearing) during camera movements and blinking on very quick animations (e.g., bright explosions), but can cause somewhat slower rendering and short input lags.
- Decals: enabling decals like dust or blood on characters can affect CPU performance.

Turn off ubersampling. I dont own the game yet, but it's blatantly obvious 99% of rigs will not be able to run ubersampling at stable 30+ fps. Max out everything else, but ubersampling is the super awesome cherry on top that is really built for future technology.

I seem to be performing decently as well on high

CPU: Intel Core 2 Quad Q9650 (3.0ghz)
GPU: ATI 4870x2
Resolution: 1600x900 (I was getting a bit paranoid about performance so I dropped a res. It may have been the camera blur that put me off though but It's off now and I'll try it at 1080p again)

And yea, as EatChildren said above me, don't even try to run ubersampling unless you're on tech from next year. As the readme states, the game already a bit of the beast and ubersampling is rendering entire scenes multiple times for quality.

From the User.ini in Documents\Witcher 2\Config:


Change the MouseSensitivityY setting to a negative value and presto, your mouse is inverted. Quick fix until CDPR adds it to the menu in a patch, if they do.

25-30 fps until I reached the first fight. FPS drops into single digit. Any solutions?

Anybody know how to solve the launcher issues? After I typ in my key the launcher vanishes. I tried to have the game run with fullscreen disabled incase this was the solution like it's been for some gaffers. But each time I start the game it auto-detects some random settings anyway.

Any idea?


Apr 21, 2005
I'll post my specs/performance tonight when I get to play it. I suspect I'll be playing Ultra @ about 30 FPS.

Check out your user.ini (in C:\Users\yourname\Documents\Witcher 2\Config) file type. If it's UTF-8 you'd better convert it into ANSI, or the game can't read it.

Just know that the Ultra preset sets "Ubersampling" to 2 by default. You're likely gonna want to go into the external config menu and disable that.

I wonder what kind of setting i'll need to run this game at decent FPS(say 30) if i have a AMD quad core Phenom 3.2ghz CPU, 4gm of RAM and a 9800gt 1gb.

I'm still thinking of changing my video card since the fan does some annoying noise sometimes when i boot my computer.

What kind of godless heathen would want to do this?

LMAO. Me =\

For some reason, when playing games, my brain treats them as 3d and not 2d, so controls are more about manipulating about my character's perspective, as if I'm controlling a 3d model of myself in that world .. rather than simply getting a cursor to a graphical object .
It's weird, I know.

Most of my friends play FPS games like it's its whack-a-mole, just moving reticule to target and pulling the trigger and that's that. I envy them, cause it's so much simpler that way. They are moving their character's feet, but there's no thought of torso or head control - there is only the reticule. So it's basically "Missle Command" for them, but while pushing a left thumbstick. So inversion (of course) makes no sense to them.

We still argue about it all the time for kicks =D. Even for over the shoulder style games likes Gears, I still invert.
Feb 5, 2009
Good thread idea minsc. Too much derailing in the OT, even with people making multiple posts above OCing.

Question, i left the preload where it stopped to download the last remaining part of the 9GB. So havent had tjhe chance to install the game yet. Have multiple questions:

1)I have my CD key but where im supposed to use it? I was thinking GOG version was DRM free.
2)When and how will i apply the patch?

So in a sense i'll have to connect the game to the internet at least once to properly play it?

Thanks for any help.

Wasn't expecting to run it on Ultra, but looks like I'll be fine with High. All I care about are the textures anyway, so I'll sacrifice the rest.

Hoping I come back to this thread later in the day to discover that AMD put out a Crossfire profile for this game.

Otherwise, I will be playing Crysis tonight instead. Oh well.

I will be seriously annoyed at AMD's driver team if not. FFS, it's their JOB to make sure their GPU tech supports the latest games.

Older patch notes:
Patch 2.0 notes said:
Arena - is a new gameplay mode that is separate from the main adventure and narrative of The Witcher 2. In this mode, Geralt of Rivia duels a variety of foes to the death in a gladiatorial arena located in an unnamed town somewhere in the Northern Kingdoms. In addition to winning gold and valuable items, players also receive points for their wins. They can then post their point totals on-line to compare their achievements against those of other blood sport enthusiasts around the world. Geralt can encounter both foes and allies in the arena. He can recruit the latter for a fee to assist him during his most challenging clashes.
To post your point totals to the forum, you must be registered and have a forum account! Register and establish your account directly through the game launcher or go to www.thewitcher.com. You can then log in to your account via the launcher.
IMPORTANT: Players using mods to alter their character attributes and statistics will not be able to post their point totals from the arena to the server. This is a necessary precaution to prevent any attempts at distorting competition or misrepresenting player achievements.

Tutorial - The game tutorial takes the form of a brief adventure during which players learn how to use a range of game mechanics and functionalities. Assuming the role of game protagonist Geralt of Rivia, players save a wounded knight named Bolton of Ironford while learning game controls as well as the basics of combat and alchemy. This transpires step by step as the tutorial guides players through a series of minor missions. Upon completion, based on demonstrated abilities, the tutorial recommends the difficulty level which the player should choose in embarking on the main adventure of The Witcher 2.

Dark Difficulty - The "Dark" difficulty setting is the most demanding difficulty level in gameplay terms. Under this setting, each and every foe represents a significant challenge. In addition to raising the difficulty bar, the module includes several new sets of equipment/items that are linked through a dark legend detailed in the Journal. Once all their components have been collected and donned, the Blasphemer‟s, Oathbreaker‟s and Kinslayer‟s outfits provide great advantages in combat. The swords included in the outfits strip opponents of Vitality while supplementing the witcher‟s. However, given that they are cursed, the swords provide no benefit and harm Geralt by sapping him of Vitality as long as the outfits to which they belong remain incomplete.

Corrections and improvements to combat:
1. Numerous improvements have been made in the targeting system.
2. Parrying is now unlimited (even when Vigor is completely depleted), though parries no longer cancel all damage (maximum 50% reduction once the relevant ability has been acquired).
3. Responsiveness of game controls has been improved. This includes but is not limited to casting Signs, parrying, and attacking immediately after evading an opponent‟s assault.
4. Geralt's attacks are no longer interrupted by attacking opponents. Attacks are now contiguous and foes cannot interrupt Geralt‟s attacks by landing a blow.
5. Assorted fixes now prevent opponents from incessantly attacking Geralt after he has been knocked down. Geralt can no longer be knocked down repeatedly in quick succession. Also, he rises quickly while evading subsequent attacks.
6. Geralt no longer attacks opponents located behind other opponents positioned nearer to him.
7. The target locking system has been improved. Preference is now given to previously highlighted targets.
8. Target selection has been improved. Priority is now given to foes affected by a critical effect facilitating the completion of a finishing move.
9. The additional two steps Geralt took after mounting an attack with the W, S, A or D key depressed have been eliminated.
10. Attacks can now be continued even when a key controlling Geralt‟s movement (e.g. W, S, A, D) is depressed.
11. Attacks can now be continued if the attack key is depressed immediately after the final strike of an attack animation sequence.
12. Geralt can now pivot 180 degrees immediately after completing an attack.
13. Assorted problems with key responsiveness have been resolved. Keys no longer need to be depressed twice or more to trigger a given action.
14. A distance attack problem has been resolved. Geralt now mounts distance attacks (lunge with sword in hand in the Fast style) when opponents were located at a suitable distance from him.

Other corrections and amendments:
15. Casting several bombs no longer blocks further inputs.
16. An option has been added to the configuration tool enabling aspect ratio to be set independently of resolution.
17. The amount of disk space required for game patching has been reduced.
18. The loading of selected Witcher 1 game saves no longer causes the game to crash.
19. A greater number of monsters now appear in the cave leading to Loc Muinne.
20. Improvements have been made in the manner in which monsters are spawned in the mist in Chapter 2.
21. The visual effect accompanying Adrenaline use no longer disappears prematurely.
22. Archers now draw their swords more quickly when Geralt approaches.
23. Mages no longer automatically cast shield spells when Geralt casts daggers at them.
24. The game is now paused when Geralt executes a finishing move in combat.
25. The troll in Chapter 2 has been corrected. Previously, in some circumstances he could not be attacked.
26. Physics on cast daggers have been improved.
27. The site for aiming daggers is now more visible.
28. Geralt‟s animation when he dies while casting the Axii Sign has been corrected.
29. An exploit in the fight against Letho has been eliminated. Previously, this foe could be killed by casting bombs in quick succession.
30. An exploit related to the „Insane‟ difficulty setting has been eliminated. Previously, game saves could be loaded with difficulty set to this level, which was contrary to design intentions.
31. Camera positioning/operation has been corrected during the boss fight against the kayran.
32. Camera control via gamepads has been improved.
33. Assorted adjustments have been made in mutagen statistics.
34. The "Junk" filter in the Inventory has been adjusted to provide for correct item filtering.
35. In the Inventory, the dialogue window warning of prohibited actions has been corrected.
36. Assorted corrections have been introduced to the mini-map in Chapter 1.
37. Audio balance throughout the game has been adjusted.
38. Erratic character teleportation in mini–games has been eliminated.
39. Assorted adjustments have been made in animations applying to nekkers.
40. A minor bug in the “Scent of Incense” quest has been resolved.
41. Numerous minor fixes have been introduced in character lip-sync throughout the game.

Description of Mahakaman Rune Sihill imported from The Witcher savegame have been corrected.
Patch 1.3 notes said:
1. New FREE DLC – “A Sackful of Fluff” is a new quest in Chapter 2 of the game. To start the quest, visit the eccentric Elthon, who inhabits a solitary hut near the quarry outside Vergen. The quest will prove most rewarding to those who demonstrate patience.
2. Game now supports 4:3, 5:4, and 16:10 aspect ratios.
3. Item storage has been added. Players can now store items from their Inventory at inns. To leave items in storage or collect previously stored items, talk to innkeepers.
4. A ‘Junk’ panel has been added to the Inventory to provide greater clarity in item classification.
5. A new menu option has been added under ‘Extras’ – this enables players to view in-game animated sequences (flashbacks, memory flashes, dreams stolen by harpies) outside of the game.
6. A ‘Quickload’ option has been added under the F9 key.
7. The game's HUD can now be hidden in order to produce HUD-free screenshots! On newly installed game copies, the option to hide/show the HUD is available by default under the 'H' key. Users who have modified the key assignments on their installations should go to the 'Input Settings' dialogue of the Witcher 2 Configuration Tool to assign a key to this option. Please note that the game cannot be played with the HUD hidden.
