Forums - Microsoft Discussion - Opinion: Next Gen Console Lockhart, Anaconda and PS5 will be built to do Hardware Ray Tracing

Machiavellian indeed.

Excellent prediction if the rumours are true.

Correct me if I'm wrong, but will ray tracing help with loading times as well? No more light / cube / shadow / reflection maps etc to load for each scene, instead rendered on the fly. That should also reduce the game size, faster downloads, faster patching. It should also reduce the workload on the development side.

Not really, cube/shadow/reflection maps are mostly generated in real time using either the fixed function units or shaders. Light maps hardly take any storage space. You're going to be disappointed if you think ray tracing will improve loading times but it's going to vastly improve visual quality leaving last gen systems in the dust ...

I was under the impression Assassin's creed Unity was so big (file size) because of the light maps. Every bit helps anyway, but the SSD will have a much bigger impact of course.

Ray tracing in VR will be magical. No clue if the ps5 can pull that off, yet holding a flash light with ray traced light and shadows is going to be mind blowing :)

Meh, let's save ray tracing in VR for the upgraded PS5 SKU. My biggest hope is that the PS5 will double the ray count of the RTX 2080 Ti to 20B rays/s with some improvements to feature set. Personally, I'm more excited about using ray tracing for a more diverse set of materials like glass which can exhibit refractive/transmissive properties. Caustics are more exciting than bounce lighting or shadows IMO ...

Afaik resolution is the main determining factor for ray tracing. Since VR is lower resolution it should be more do-able to ray trace in VR than in 4K. Currently the wide fov (and double view) is what's hampering VR, however it should need less ray trace samples than a 4K game.
