NVIDIA RTX Mega Geometry is coming to The Witcher 4

Oh who cares about that, it will have path tracing man, path t r a c i n g!
But I'm not kidding, it's probably going to look sick on PC(only), and guessing 2028-9.

On the other hand this RTX Geo tech seems like such luxury in a way. Like who cares about individual needles on a pine tree while galloping on a horse through a forest?

I was thinking the same thing.
 
It'll run at 10fps with this new feature on.
But look out for Nvidia's next gen where you can use this feature with frame gen + DLSS to get a whopping 40FPS!
Yeah, I remember trying to run Witcher 3 with hairworks on with my GTX 970. Not a fun time even on 1080p!

A feature didn't add much. In fact I had turned off most of the time and never knew it. Geraults hair always looked fine.

Other characters....never had good hair with or without it on.
 

The Witcher 4's RTX Mega Geometry Foliage Demo Ran at 4K@80FPS (with DLSS Quality) on a 5090.

At GDC 2026, NVIDIA and CD Projekt RED showed a demo of the Polish studio's The Witcher 4 using NVIDIA's RTX Mega Geometry to path trace forests for the first time.


Now, NVIDIA has released the full video replay of the GDC 2026 session 'The Future of Path Tracing | Best Practices, Optimizations & Future Standards', which includes lots of interesting details on that The Witcher 4/RTX Mega Geometry demo.

Martin Stich, Senior Director of Engineering at NVIDIA, introduced the company's latest work based on Mega Geometry: a level-of-detail system for foliage. He notes that no new APIs or hardware are required, since it is built on the existing Mega Geometry APIs.


The demo scene, which includes tree assets provided by CD Projekt RED (presumably used in the development of The Witcher 4), features 60 million plants of 200 different species and around 1 million trees. It takes place on a 5×5 km terrain, entirely held in memory with no streaming, as evidenced by the lack of any pop-in or other typical LOD issues.


Larger trees have up to and over 10 million polygons each, and everything in the demo is modeled as actual geometry, meaning no alpha maps or cards, down to individual pine needles. Martin's favorite stat from this demo, though, is that if you flattened the entire scene into a triangle list at full LOD, you would get over 5 trillion triangles. Of course, The Witcher 4's RTX Mega Geometry foliage demo features fully dynamic path-traced lighting with pixel-perfect shadows, and everything can be uniquely animated.

58 frames? Cool, thats not too bad i have to say. Looking forward to the Witcher 4

The game's gonna eat my poor 4080 alive though, and I sure as shit can't afford to upgrade any time soon -_-. It's a bummer, but I'm also looking forward to it too.
 
Nah, man. I think you will be fine with a 4080.
I hope you're right man. I don't have the triple frame gen like the 50 series, just the single, so I was thinking that might not bode well for me, but maybe it'll be really well optimized like Cyberpunk was. Here's hoping :D

Ya know, it's funny. I bought a PC back in the day because I wanted to try out Witcher 1, then upgraded to a better machine for Witcher 2, then upgraded to 980 specifically for The Witcher 3 about a decade ago, I upgraded to a 4080 from a 2080 for Cyberpunk, and now I'm wondering if I should upgrade for Witcher 4.

CDPR are responsible for like 80% of the PC upgrades I've made in the past 15 years.

Believe in your 4080, mate.

They're not saying with or without framegen. Might as well be with 6x FG lmao which means its fucked.
 
It seems that certain video game companies suffer from Alzheimer's or excessive fanaticism among their users.

The same company that released The Witcher 3 with a downgrade that will be remembered in the history books.

The same company that released Cyberpunk 2077, which was an early access title and was one of the games that the PlayStation Store had to refund players for (God, that's awful...).

Unreal Engine 5 and CD Projekt are going to be synonymous with catastrophe.

LOL.

You can say a lot about CDPR but not that they don't know how to create great looking games, even after downgrades (caused by consoles) TW3 was the best looking open world RPG (much better than Fallout 4 from 2016). Cyberpunk was obviously too ambitious for PS4 and X1 (I wont defend their decision to make those versions at all) but PC versions is still in top 3 graphics to this day.

Currently they are fixing UE5 for Epic and recently released one of the most impressive SW2 games.

Let's be honest, Cyberpunk 2077 is all graphical window dressing; behind the scenes, there's nothing significant.

Its physics engine is awful, the NPC AI... you only have to play RDR2 to realize the incredibly low level of detail in that game.

But it's true, it has a flashy presentation thanks to the very good implementation of ray tracing, which makes it beautiful, but that's about it.

What are you talking about? RDR2 is PS4 game that looks like PS4 game, with last gen lighting and all.

It has better physics and NPCs, that's for sure - but most of the game world is quite empty.

It's a technical GDC talk. Not Jensen PR. If it used frame gen, they would declare it. They plan to open source all of it later this year, so anything falling short of expectations will get torn apart.
 
Yes, it's all very impressive; but between the blurry image quality and stuttering, I'd have preferred to see them stick with the Aurora engine.

Just a suggestion, lossless scaling works really well in many games, and can get you that 3x multiplier if it will be needed. Of course, Witcher 4 may be a game that it doesn't work well with, we will have to see.

The software is somewhat divisive, but I have found some great use cases for it.
 
You must be gay.
actually i like the aspect of role playing as a handsome guy in medieval ages that ll fuck literally everything that walks in two legs and have a pussy.

controlling Ciri we ll no longer have scenes like this

[

look how happy he looks ( i had the same smile playing this back in the days )


also, it would be awesome to have Geralt back loving everyone at high high fidelity

You sound like you controlled Geralt during scenes like that. In either case, you are going to sit back and see some boobies. And depending on who you choose to romance, may be more than a pair. And if you prefer watching hetero only, just imagine you are the other person that Ciri is boinking and... problem solved? I'm sure he will be smiling too!

This is just such a non-issue, man. She even looks pretty now, so you don't even have that excuse anymore. Just say you are tired of playing as a woman because of "twisted woke feminist DEI" and be done with it. At least that would come across as honest.

yeah, cause my dream is to role play a medieval lesbian romancing other medieval lesbian... peak male role playing fantasy.

lol. Is Ciri being lesbian canon? I thought they left it ambiguous and you can choose? If she can't fuck men at all, then I can empathize with your complaint more…
 
As long as I can still play this max out on 1440p without running out of VRAM and still able to have a constant 60 fps+ with dlaa framegen x2 or dlss without framegen on my 5070ti and 9800xd3 than I'm fine with this.
