Real-Time Ray Tracing with Neural Network Denoiser (Optix 6.0)
A quick survey on the effects of adding a denoiser to a full-on ray traced rendering project

If you have an RTX graphics card and are willing to download the source code, I strongly advise that you do.
The videos are shot in a higher resolution than the actual footage. This is to prevent a lot of quality loss, but some compression quality loss is expected.

1SPP, 1SPP denoised, 1024 SPP, and 1024 SPP denoised Renders of Crytek Sponza, Rungholt, and Cornell scene
1) What would be the minimum acceptable framerate (in FPS) for real-time game graphics? *
2) What would be the minimum acceptable resolution for real-time games? *
3) On what device are you running the demo? (graphics card type and amount of memory) (If you've watched the recorded footage leave this empty)
4) Does the overall quality of a 1 sample per pixel (SPP) image improve when denoised? *
Follow up on Question 4, could you elaborate further on your answer?
5) Is the difference in quality between a 1 SPP denoised and non-denoised image, worth the trade-off in performance? *
6) Is the difference in quality, between 1SPP denoised renders and multi-sampled (Example, 100SPP+) renders, acceptable to try and achieve real-time rendering? *
7) Could a full-on ray tracing approach using 1 SPP, that is denoised, be viable as a way of rendering game graphics? *
Follow up on Question 7, could you elaborate further on your answer?
