Update: Black Zero over at Guru3D put together a more thorough guide that will likely be updated from here on. I recommend checking it out if you have any questions.

http://forums.guru3d.com/showthread.php?t=366244



Before I start, I use a base resolution of 1080p, so I've only tested it at that resolution, and in Windows 7. It should work with other resolutions, though.

I want to give all the credit to this motherfucker over here, Mr. Lolman. It's amazingly simple and it works. (It's in German, and I don't speak German, but I was able to figure it out pretty easily.)

First, make sure GPU scaling is OFF. (seems backwards, I know)



Basically, you download his little program, AMDdownsamplingGUI (aptly named) here, then open the .jar file, click "Erstellen," and you'll see:



Then change the following numbers to 2560x1440 (NOTE: In order to properly downsample the image, you have to first select 2560x1440. I'll explain a bit more below) then click "OK" to create the resolution.



Now, open up your display properties and you should have the new resolution in your list.



Clicked "Advanced settings" and uncheck this box:



or you'll get this message.

Now, select the new resolution and your desktop should scale properly. You can now start a game in 2560x1440 and it will be downsampled accordingly.

Now, if you're wanting a higher resolution, or a proper 16:9 resolution such as 2880x1620, you can repeat the steps above to create that resolution, but to get it to scale properly you must first choose 2560x1440, then from there selecting the 16:9 resolution will work.

The program was designed with 2560 in mind, from what I gather, so that's just how it works. If you choose 2880x1620 (for example) first, you'll only see a corner of your desktop as the image won't be properly scaled.

IMPORTANT: Before you shut down Windows, make sure your resolution's not higher than 2560x1440 or you'll get a black screen upon restart. If that happens, just hit F8 and boot into 640x480.

Try it out and share your experiences below. The more feedback the better.

This may be a dumb question, but how will this impact games? Can it basically make easy-to-run games look a lot better without noticeable performance hits, and make harder-to-run games impossible to play at the upscaled res?

AMD's supersampling is usually blurry as shit, and messing with the LOD settings in RadeonPro rarely helps. A lot of games don't allow forcing AA through drivers because rather than try to get them working, they simply disable the function altogether. So for those games, this is at least an option.

Yes to both. Downsampling from 2560x1440 drops Crysis 2 (DX11 w/tessellation off) from ~50fps to the high 30s for me, so it's not unplayable, but it's definitely a hit. Dead Space 2, however, I can maintain 60fps 90% of the time, and still get rid of a lot of jaggies.

Super sampling is far from perfect, especially on ATI cards and the performance hit can be absurd in certain games. This approach has vastly superior compatibility and a much smaller performance hit by comparison.

This seems a bit extreme. Do you AMD guys not have anything equivalent to Nvidia Inspector you can use to force AA? Or do you just find joy in overkilling jaggies? And wouldn't this cause UI elements to become blurry and small?

Wait, so super sampling with higher comptability AND better performance? Thanks for posting this dude. I mean can't even run SSAA in Hitman Blood Money without the framerate going from way over 60 to about 30.

And Elsolar, GUI elements shouldn't really be affected. If you take an image, zoom it up (without doing anything else) then shrink it down to its original size, it ought to look the same.

So, rendering at whatever high ass resolution, then downscaling it to 720p, the GUI should look the same as it would if you just ran a native 720, if I understand my things correctly.

It's not like when you scale from a low resolution to a high resolution, that's when blurring occurs.

But you're not "zooming it up", you're just shrinking it down. GUI elements usually don't scale with resolution, something that's 200px by 200px at 800x600 is still going to be 200px by 200px at 1920x1080. So by rendering the game in a higher resolution and filtering it down to a lower resolution, the GUI is going to look compressed and gross.

Actually, real supersampling AA, when implemented correctly, is superior to downsampling. This is because downsampling is basically equivalent to ordered grid supersampling, while SGSSAA uses a sparse grid, which achieves superior anti-aliasing performance across all edge angles.

Downsampling is very useful for games where you can't force real SGSSAA though (which I understand to be even more common on AMD than NV).

I don't think that's the case for modern games. Lots of them do scale the UI.

Right, so the GUI's scale stays the same, regardless, then shrinks down with the downsampling? That makes sense. I obviously didn't have my facts straight :p. I should look things up before posting next time. Or use the powerful tool known as logic. I feel like a dumbass :lol

Try going into Advanced Settings in the screen resolution box and uncheck "Hide modes that this monitor cannot display".

edit: also you do not need to have your desktop resolution run at the desired downsampled resolution it seems. Just set the games reolution higher. Works good so far.

Crysis 2 benefits on the fences and smaller details the most. The difference in lighting is from pausing/unpausing. Sorry.

Hit F8 during startup as if you were going into Safe Mode. There's an option there to start in 640x480.

You can delete the custom resolutions within the program. Just select them at the top and hit "Löschen"

@scitek - do you resample the pics with an image editing tool afterwards to get to the base reolution? It kinda defeats the purpose of it I think but I have no idea how to take screenshots of the downsampled shot.

I do it with 16:10, but like scitek said you need to first set up the 2560x1440 resolution, and then add 2560x1600.

I tried that but when I choose either of them I get some low 4:3 resolution instead with black borders.

Just to make sure I'm doing it right.

1) Add 2560x1440 with the java program
2) Add 2560x1600 with the java program
3) Go to screen resolution and switch to 2560x1600

Is that it?

It varies from game to game, and it's not worth the performance cost in most cases, to be perfectly honest. It's just an option for those games that don't allow AA at all (AMD has a bad habit of doing this). Dead Space 2 is one I use it for because, if you do manage to get proper AA working through drivers, things like dynamic shadows no longer work.
