Battlefield 5 and the new Lara Croft game is a great push into the main stream. I can't remember if they are using NVidia's RTX APIs, or M$'s Ray Tracing API. That can make a big difference for future compatibility. NVidia and AMD really need to cut down on proprietary add ons, it just hurts the end user. PhysX and a dedicated PhysX card, I believe, is still a great idea. Same with other items such as Hair Works. And it would definitely help with NVidia's oversupply issue of the 10 series cards. But if they had opened it up to AMD, it would have become more main stream, covering more games. That could mean more GPU sales, including lower end cards for dedicated PhysX, Hair Works, etc.
The lack of benchmarks is rather surprising. I watched the NVidia release on Facebook, and I caught right away that any comparisons that were used were only talking about Ray Tracing. I also noticed a couple of 'hick ups' in the games they demoed, it wasn't as smooth as they were claiming. That could easily be just a matter of their hardware set up for the big screen, etc. But, again, since there are no benchmarks released, especially from Tom'sHardware, and now this article to suggest not buying right away, I definitely don't see the need to upgrade my two 1080ti's in SLI.
