CG artists and scientists use them with mobile workstation laptops, not for terribly heavy work- you still need beefier desktops and server farms- but for smaller tasks that can be worked on while traveling.

pyrotek posted:Control almost seems like it was designed specifically to show off the various ray tracing effects. The art direction definitely had fancy reflections in mind, even on consoles they have unusually good reflections. Their SSR fallback is some kind of rough approximate raytrace (voxel cone tracing?) that aligns correctly with the scene unlike the usual janky cubemaps. Swapping that technique out for accurate and dynamic RT reflections is just the icing on the cake.

being able to offload video/photo/audio processing to an apple igpu would be big for ML, they've been pushing their own API/custom silicon for inferencing on their mobile devices. being able to develop natively on their PC hardware would be big too

Does Apple have their own GPUs yet? I thought they were still grappling with having Imagination bought out from underneath them by the Chinese government?

The 'bionic' chips that started in the 8/X have their own GPU. Their first one was allegedly a 30% improvement over the last PowerVR they used.

Apple's "in house" GPUs were so obviously "influenced" by Imagination's patents that they have decided to license basically everything Imagination offers on a gigantic, multi year deal instead of lose that court case. So Apple basically has access to the full PowerVR designs (including AR and ray tracing tech) and their own stuff too. (the first part of that answer is speculative of course, the rest regarding the license is confirmed and PR announced)

Although perhaps maybe this will come into play due to some architectural change in Ampere (just spitballing obviously). I mean someone clearly thought it helped in some way. Could just be scaffolding for the future.

Whether it makes any difference is going to depend on the game and how heavily loaded the GPU is. If the developers code was handling GPU memory well enough, nothing's going to get better. Where you might see some improvement is in minimum framerates. The new WDDM is resolving some of those multi monitor / differing refresh rates bugs that've been hanging around for ages.

I'm seeing less flicker since updating to the latest W10x2004 driver! I don't know if that's because I hosed something up trying to get non-temporal AA looking okay in Apex Legends or what, but it's welcome.

Nice. IIRC, games usually only had RT GI like Metro Exodus or RT Reflections like Battlefield.

Dogen posted:Didn't control have both? Honestly the whole thing is somewhat confusing. Yeah Control has RTGI (the "indirect diffuse lighting" setting) but the improvement is relatively subtle compared to RT reflections, most of the environmental lighting is static so the default fake baked GI is decent enough. https://images.nvidia.com/geforce-c...-on-vs-off.html https://images.nvidia.com/geforce-c...-on-vs-off.html https://images.nvidia.com/geforce-c...-on-vs-off.html The ambient occlusion you get from RTGI is better than the default SSAO but there's not much bounce lighting you didn't already get from the bake. It'll probably be more dramatic in Cyberpunk where the day/night cycle limits how much they can bake, much like Metros RTGI.

repiv posted:https://www.nvidia.com/en-us/geforce/news/cyberpunk-2077-ray-tracing-dlss-geforce-now-screenshots-trailer/ Looks very cool! Why do you need ray-traced ambient occlusion though? The write up says (bold is mine): quote:Ray-Traced Ambient Occlusion - Ambient occlusion is a shading and rendering technique used to calculate how exposed each point in a scene is to ambient lighting, which results in the rendering of new AO shadows that ground objects and naturally darken surfaces, objects, and other game elements. In Cyberpunk 2077, ray-traced ambient occlusion can be used with local lights to approximate local shadowing effects where shadows are missing, greatly improving the quality of the ambient occlusion effect. What missing shadows? Is this compensating for an optimization that drops rays? E: As in AO is a hack to simulate accurate ambient lighting. RTX gives us accurate ambient lighting and GI and all that good stuff. So why do we need ray-tracing assisted AO?

It sounds like their RTGI rays are only sampling the skybox and emissive materials, not evaluating local lights, so you won't get any bounces from those. Probably a concession for performance. They must still be using the baked GI data for the local lights and relying on SSAO/RTAO to fudge the indirect shadows. I believe that's how Metros implementation worked as well - RTGI for the sun and RTAO for everything else. repiv fucked around with this message at 23:59 on Jun 25, 2020 |

Thanks for the explanation. I was and am kinda hoping that a 3080ti with DLSS 2.71828 cranked up can render an image based on the laws of physics, circa whenever we figured out basic reflection and refraction (say, Newton?), without too many baked in assists. Sounds like we're still a long way away from doing that at, say, 3440x1440@60Hz.
