It would have been smarter to just not mention RT rather than say "photo mode only"...
That being said... from reading the thread I don't think people understand that a reflection is redrawing the game world from the perspective of that reflection itself. You can draw a less detailed version of it.... but you're still drawing it twice for 2 perspectives. Then you factor in what needs to be reflecting...
A)the car itself
B)the other cars you're racing against
C)the mirrors on each car
D)the water
E)any glass building or reflective structure in the environment
And then suddenly you're in a scene where you need to draw the game world 9 times from 9 different perspectives in a single frame.
You draw them at various resolutions and detail levels but that is still an extremely tall order. I'm not sure even sure how Gran Turismo or Forza Motorsport will pull it off.
Yep, and with racing games you have multiple fast moving cars that need to have all of those ray traced reflections, it's a huge undertaking.
I'd imagine that what we will see in FM and GT is RT for the player car only (and no ray tracing on any other potentially reflective surfaces like puddles etc) but even that might be a stretch at 60fps. Wouldn't be surprised if all it ends up being is ray tracing in replays and photomode.
It was supposed to be added to assetto corsa competizione but the developers decided to scrap it because they decided it didn't add a worthwhile improvement to the game when in motion - basically it wasn't worth the performance penalty. Demo starts at 3 minutes 16 seconds:
Would they enable it for PC? Maybe throw a lil AMD Super resolution in there?
AMD Super resolution is a driver level enhancement AFAIK, meaning the developers don't need to add it to their games for it to be an option for AMD users?
