i figured the Ray tracing was only used for reflections.
I'm insanely impressed by its implementation in BF5. It's still a mental price-point, but this is gonna rock in a generation or two! I think it could be one of those technological leaps we haven't had for years. Well, except minor differences in AO implementations.
Realistically you can render entire scenes with it and get almost perfect global illumination and the likes. It's sort of been the holy grail of online rendering for a while now because it's so damn hard to do whilst keeping the frame time down. But it makes sense to use it for reflections only to start with, a much more limited surface that doesn't need quite as accurate calculations to look right. RTX will be a good stepping stone into progressing real time ray-tracing. Reflections in games past the super early 2000s have always been a problem due to the increasing complexity of geometry preventing us from using that age old hack of "fuck it just render everything again". So it's nice to see some proper progress in reflections.
this was my thought on RTRT in the original reveal of RTX features in BFV in the FP thread here. Real time ray tracing will only be good for doing accurate lighting for some effects for a very long time IMO. Which is okay, but it kinda doesn't blow me away too much.
Not only that, any lighting information you have precalculated can be used, so you only have to do a single bounce for reflections, instead of multiple bounces.
Apparently this isn't even properly utilizing Turing/RTX tech yet, just DX12 async compute (I think). All these demos are making me hopeful that older forward thinking GPUs with good support of the DX12 feature set, like Vega, will stand a chance. If developers finally start taking advantage DX12's super flexible multi-GPU support as well, we could maybe even see raytracing acceleration using vega APUs, older cards, etc. That'd be amazing (and hilarious IMO) seeing as you can pick up two RX 580s used for under the price of one good RTX card. Hopeful that when the dust settles more games will be optimized like Doom and Wolfenstein - if you've ever played one of those on vulkan or DX12, AMD cards optimized for the stuff get absolutely silly performance. I was able to max out DOOM at 3440x1440 60fps on a 4 year old R9 290.
We definitely need more of this! enough with the closed off, arbitrarily limited bullshit! This is a prime use-case of Multi-GPU gaming. Also for DLSS alone there's this huge potential of keeping mid-range cards going for longer, but people are out there legitimately bitching about "fake 4k" and how "this is not a good thing!". The same assholes who preach about PC-gaming being about choice of settings turn around and go all elitist towards people who don't have the stupid amounts of money to jump from 1080>1080ti>2080>2080ti every 8 months like some upper-class enthusiast. I hope there'll be a more universal, open-standard version of DLSS. I mean, it's nice. But it's borderline useless when the devs have to go out of their way to directly implement it. It's gonna go the way of TXAA if they don't find a way to implement it as a driver-level upscale option instead. Doom and Wolf on my 980 gets 120 FPS at 1440p. Those devs (or that engine) did one hell of a job with those games! It makes the entire industry look incompetent by comparison!
