It's simple. The new Ultra settings is RT + DLSS Q. Don't have to expand on the RT part, but regarding DLSS, it improves image quality when games use TAA, especially poor implementations of it.You should expand upon your "And then you realize the 6900xt os 2 generations behind" behind comment.
1) Do you mean in terms of relative performance in just CP2077 or overall?
2) Do you mean in terms of VRAM?
3) Do you mean because of proprietary software such as DLSS?
4) Do you mean because of RTRT capabilities?
Feel free to expand from there and list other thoughts about why the 6900XT is 2 generations behind. I'm curious as to why you think that and I'd be curious as to where you'd get your supporting info on.
So the 6900xt is a high end card that....can't play at high end settings.
And don't get me started on FSR. God almighty have you tried that thing? The amount of sharpness makes me wanna vomit after 15 minutes
