Yeah water is definitely where RTX makes the biggest visual difference^^ Personally though I don't find myself noticing global illumination bits etc as am too busy looking at the world as a whole or exploring etc
I actually dropped res yesterday to try playing a few hours with RTX on (Psycho SSR and Psycho RT Lighting) and this was what my performance was like with RTX On (left) and off (right) at 2560x1080 custom optimised settings of high/med/ultra:
The funny thing is that when driving in the city regardless of population density or traffic, the frames drops quite a bit but soon as you get out the acr and walk around somewhere else it's back up again which kind of points to optimisation issues during motion/physics segments?
I am unsure if I want to continue playing with the above settings or go back to 3440x1440 RTX off. I like both, RTX on looks nicer with water involved. bt means I'm rolling with 2560x1080 and as such a lower source image for AI to work with on DLSS, whereas 3440x1440 is sharper still and uses a higher res source image. In practice during gameplay I'm hard pressed to notice a difference as both look great, it's only in screenshots that you notice one is obviously a smaller res. I think what has helped increase 8-10 fps though is the higher GFX overclock I made last night. I have been since day 1 just relying on the auto scanned core clock OC taking it to around 1930MHz from the factory OC of 1815, but it seems this card has a lot of room to give and uses the 2080Ti VRAM chips so essentially a 1GHZ OC on the VRAM is possible too but I've dropped to 900MHz as a safety catch.
Lastly, the bug I mentioned yesterday where all my perks de-applied themselves? I must have bought this as the RD at some point and not realised:
Oops
