a lot of the reasons i keep saying the 20xx line is a rush job from Nvidia are echoed by the game devs.
they should've had ES running just for this kind of research months ago. and/or Nvidia should've waited on a process shrink so the higher speeds would result in a lower frame hit.
if this finding from Remedy is consistent across devs, then expect to find RT in fewer battle royale games and in more strategy games where frames/sec are not as vital.
and... it's not like AMD isn't involved in RT they are, they just haven't released anything specifically for it and they will not need RT cores.
MS is the force behind RT and MS doesn't pick sides (except Xbox lol) between AMD and Nvidia.

You have to start somewhere when it comes to Ray Tracing. I say well done to Nvidia for this. It may not be at the Resolution that everyone wanted. AMD will definitely get into this, they have to to stay relevant in the market. There is no way they won't as Microsoft has it enabled in the latest version of Windows 10.

I'm truly confident in the optimization possibility between AI-based denoiser and lower-resolution RT workload. (see the Star Wars demo from HH with DLSS running fairly well at high resolution despite extremely expensive post-process effect like convolution bloom, and ultra high quality depth-of-field for cinematic experience etc...)
We're still extremely early for this tech and no one can deny Nvidia is taking a risk shipping those products.
All the implementation demos we've seen so far are rough first pass after a couple weeks with the cards, barebone drivers, early test version of windows with DXR support (as it was just released last week)...
Only time will tell, but we can already see the enthusiasm of major studios like DICE/EA (and their R&D SEED division)/Remedy/Epic Games...
I also see a lot of possibility for indie studio using unity/UE4 to get access to otherwise extremely expensive features like realtime GI, faster lightmap baking etc...

What is "Raytraing"?

This may be the future but it just isn't ready for prime time yet. We will enjoy this feature in a few generations. I see no reason for anyone to buy a 20xx series simply because of Ray Tracing when it's not even mature enough to be used yet. That is a massive hit on performance.

Nice to see. I guess in due time we will see what AMD has to offer in comparison.
Would be nice to see team red on top of the performance per watt scheme of things once again..... Make the "others" tighten up that shot group and make things more competitive price/performance wise!!
PLEASE AMD bring some big guns sooner than later and shut down this BS excuse of pricing that has come about today!!!

They honestly did neither. Even in Ageia's absurd maps/demos there was physics enabled on everything just for the sake of it and the performance was bad:

Even now devs/third parties are more than capable of building physics middleware for GPUs utilizing DirectCompute and whatnot and no one does it.
Lol what are you talking about? None of the RTX games so far even utilize the tensor cores and even if they did the performance impact from RT isn't even the denoising process. So adding more tensor cores, even if they were utilized, wouldn't even improve performance.

The sad truth is that Turing is too expensive for the conventional performance upgrade it provides and too slow for its marquee feature (ray-tracing). By the time developers get deep enough into ray-tracing, the 7nm GPUs will be out with better HW implementation and (hopefully) more reasonable pricing.

Unfortunately they did not optimize the demo ... will be nice to see what the final optimized product looks like next year.
