It's genuinely amazing how close to a useful image it's generating in under half a second, but we're still a couple of orders of magnitude too slow to replace baked shadowmaps for full GI.
Since you are usually moving when you're actually playing a game, the typical image quality of the entire experience is this 'dark smear', laggy, splotchy mess that visibly runs at a fraction of your framerate. Top image was taken within a few frames of me moving the camera, bottom image was the desired final result that took 3-5 seconds to 'fade' in as the temporal denoiser had more previous frames to work from. This is based on previous frame data, so with the textures turned off and the only image you're seeing is what's raytraced. So how do they render it in a fraction of a second? Meet Green RT Fakery: It takes 2060 about 20 seconds to generate a decent quality frame. Now, let's move to " full RT" shall we? Let's be generous, Quake. This benchmark applies 1 simple pass of Path Tracing to the lighting scheme which is hardly cause for celebration or even worth mentioning as the path tracer was not given enough timeĬorners Don't Look Like That: Regarding Screenspace Ambient Occlusion So PCGamer is essentially stating this technology is as sophisticated as a scene that is rendered per frame over several hour's and minutes at a render farm. Attempting to label this benchmark a Full Path Tracing Benchmark as PCGamer has only does a disservice to gamer's unaware of what this actually intel's.
When path tracing is applied to all elements of a scene, diffuse maps/shadows/reflective caustics/refractive caustics/glossy/transmission/volume scattering/transparency/Emits/AO at 1024 render passes in real time then it may be considered an actual Path Tracing benchmark. Click to expand.There is no true path tracing performance given, this is ray tracing performance tested plain and simple - 2 low passes of path tracing applied to lighting in a scene should not constitute specifying this test is benchmarking path tracing in any meaningful way.
