The NvRTX branch of the impressive Unreal Engine 5 Zorah tech demo sports some advanced features that even the most powerful GPU on the market cannot handle at native 4K resolution properly.
As shown in a new test video shared by Compusemble, advanced features like Mega Geometry, ReSTiR Global Illumination and Path Tracing and more can tank performance at native 4K resolution even on an RTX 5090 GPU, the most powerful GPU currently available on the market. In some scenarios, the demo runs at a whopping 13 FPS, proving how gaming hardware still isn’t ready for some of the advanced RTX features NVIDIA has been working on. Things get slightly better with NVIDIA DLSS, and it’s only in Performance mode that the RTX 5090 can run the demo at above 30 FPS in the same scenario that tanked performance at native 4K resolution.
Even though the Unreal Engine 5 Zorah demo cannot be run at acceptable performance at native 4K resolution, there’s no denying that some of the technology is impressive. Among the new features that have yet to be implemented in games is RTX Neural Rendering, which can quickly create a neural representation of thousands of textures to save VRAM and RAM much more than the currently used compression tech. More information on Neural Rendering can be found on NVIDIA’s official website.
