Is Unreal 5 now mostly software-rendered in the Nanite mode and only large triangles (>32 pixles diameter) are HW-accelerated?

- Jasper_ 4y agoAnything animated isn't supported as well, only static meshes.
- jiggawatts 4y agoEverything you see made by the Unreal engine is hardware rendered. More and more computations are being offloaded to the GPU over time, not less.
- bitL 4y agoI thought so as well, then I read the Unreal 5 SIGGRAPH 2021 presentation where they stated: "Turns out we can beat the hardware with triangles much bigger than expected, far past micropoly. We software rasterize any clusters whos triangles are less than 32 pixels long."
- xpl 4y agoIt is still done on GPU, you just don't use its builtin triangle rasterizer and do the rasterization yourself using "compute shaders" (programs that run on GPU). It doesn't mean they use CPU for rasterization.
