Skip the build bit and jump to 6:20 for ray-tracing performance in Minecraft, Battlefield 5, and Control. (TLDW: he now gets well over 60 fps with DXR.) This bodes well for future games and GPUs.
I think it does bode well however I still have some unanswered issues that seem to persist when you look at the bigger picture:
1. Turing charged a lot for RTX and what has actually transpired in the past 2yrs is exceptionally poor value, with a high amount of oversell. Nvidia should be held accountable for that its not ok for the media and reviewers to overlook it.
2. If someone buys a high end GPU from the nextgen for their 4K monitor are they going to have to drop down to 1440p to play titles with RT content on?
3. I have seen other graphical effects such as Screen Space Reflections deliver good results too without needing RT, what about other less compute heavy techniques?
4. RT seems to have a dependency on DLSS for higher resolutions in order to be practical, but DLSS has a poor adoption rate and doesn't appear to apply to any legacy titles yet most gamers continue to enjoy games like GTA 5, Witcher 3 and Skyrim i.e. anything that requires developer support to code into the game rather than the native hardware and drivers is a BIG problem in reality no matter how clever the technology.
