What do gamers actually think about Ray-Tracing?

Having seen openAI's latest videos from their Sora AI, which can generate almost perfect lighting in videos, there's a chance we just skip GPUs and RT in the future and let the AI draw everything for us...

MKBHD's latest video covers it well. It's not quite there yet, but the improvement in a year is staggering.


Interested to know whether some are scenes that already exist, and have just been tweaked i.e. doesnt need to think about the overall lighting, or whether it's actually drawing something fresh. If the latter then it's even more mind blowing

Yup this is sort of what we were discussing further back, the ultimate end goal for nvidia etc. probably, very interesting insight to it here:

Most likely you'll get away with less needed hardware to run RT/PT to a decent level than to run a Sora like AI and have it at a decent latency. For AI conversation and perhaps even reaction and navigation isn't much of an issue some (decent) lag.

We aren't that far hardware wise from being able to run a full path tracer like in Quake 2 RTX but much higher ray budgets and more features i.e. proper caustics (rather than fast approximation), etc. in fact with a bit of dedicated hardware it is probably possible now with the advances in software techniques and hardware.

Too bad multi GPU is practically dead...

Multi gpu was always a bit quirky anyway. I dread to think the power a dual gpu setup would be pulling these days, 2 4090's in sli would be fun.

Multi-GPU is actually much easier to load up with Ray Tracing than transitional rasterisation, Quake 2 RTX actually supports it with fairly decent results though I've not played with it much to see what is and isn't possible.

It should be possible to use explicit multi-adapter quite well with ray tracing techniques as well, but I can't really see it happening due to how niche it would be currently.

Why stop at 2 when you can have 4? :)

There was someone, I think in the clan {SAS}TB on here played with, who did simulator installs with like 8+ GPUs using ATI/AMD's professional implementation of Crossfire X or whatever it was, the latency was hideous but for professional flight simulators, etc. it was the only way to get viable performance.
 
Multi GPU in theory is easier than ever with DirectX 12, only no dev will spend the time to make it work.
It's sad that the only game that truly took advantage of it is the now ancient Ashes of the Singularity...

Limited to around 300-350w/card should have been ok. Or just stick with only 2-3 cards :p.

Back when I've got the 4080, street price for 4090 was quite high that for a couple of 4080 you got a single 4090 ( from the upper price limit).

But you can get two lower end cards, depends where the best value sits.

Plus, you could use then dor doing advanced physics and AI (as in NPCs).
 
I think I wish they had just plowed straight ahead with pure raster. IDK. I was very impressed with quake 2 RTX. But I can't even see it in almost all my games that have it - Doom Eternal for example.

If they didn't have to make these concessions to get raytracing on the go, the current gen would probably be like, twice as powerful for pure raster.

It wasn't time for it. Nvidia sold the world on it as a strategy, not because it was the right way to go.
 
For me it's came along a bit early. Saying that there is a few games I have played like Spiderman 2 where it added to the game for me. In online fast paced it's a no for me as I want the high frames over visual. Still it is the future and hopefully in a gen or two we have the power and the price to where its more viable to the masses.

Quake 2 RTX now, without even having DLSS to aid it, you can get 120+ FPS at 1080p on a 3070 without much of an image quality hit even - though the overall feel input latency wise isn't quite there with a "pure" 120+ FPS experience yet, though mostly that is down to being an older engine underneath.

Yeah Nvidia love RT as it’ll make your GPU run like crap so you have to buy a new one.
 
I love raytracing and pathtracing and I can't wait to use it in games in about 6 years time (2-3 graphics card generations). Having said that Q2 RTX is really good showing what's possible.

Some games don't bother with it like Starfield, I spent about 100 hours ship building and on my ship, looking at the great detail onboard, imagining how much better it would be if it was RTX. Just a shame about the rest of the game. Oh well.

I'm closer to upgrading to 4K gaming with a new OLED monitor so RTX just went back a step for me. I might get into 80 series nVidia cards in the future as they're more geared towards 4K but the longer cards won't fit in my Compact Torrent case, unless I upgrade that too OR get the Noctua GPU.. hmm.
 
RT is still something I find massively underwhelming. Played spiderman with it all maxed out, it's okay when you stand still to notice it, otherwise not bothered.

I don't play all the latest titles, so the most visually impressive game for lighting I've still seen is RDR2. For me it made the CP2077 hype totally unwarranted.
