While DLSS 5 was far from the upgrade that many hoped for, Nvidia has showcased some more intriguing technologies over the past few weeks, including RTX Mega Geometry. It’s being featured in upcoming titles like Control Resonant, but perhaps the most notable use is in The Witcher 4.
In its full GDC 2026 session outlining the future of Path Tracing, Nvidia’s Martin Stich talked about how one non-gameplay scene (based on assets provided by CD Projekt RED) featured 60 million plants and one million trees across a 5×5 km terrain. Despite featuring 200 different plant species and some trees having more than 10 million polygons, it loads without any streaming.
All of this is complete with fully path-tracing lighting. Perhaps the most impressive part of all this is that it runs at 4K/80 FPS, but there are some caveats. It’s running on an RTX 5090, and the 4K resolution is upscaled from 1440p with DLSS Quality mode. Comparatively, an RTX 4070 would eke out 58 frames at 1440p (upscaled from 960p).
As noted previously, none of this represents the actual gameplay or the hardware you’ll need to run The Witcher 4 on PC. At this point, it’s a cool tech demo of what RTX Mega Geometry is capable of using the game’s assets. Whether it reaches this level of fidelity and complexity remains to be seen, so stay tuned.
The Witcher 4 doesn’t currently have a launch date, though there are claims of a late 2027 launch. Officially, it’s still in full production with CD Projekt RED recently scaling up its team (among others) for the same.
