Could be a placebo but does anyone feel the resolution is not as sharp and crisp in Performance RT following the update?
Will have to do more testing, but after the first couple of races I felt things were blurrier than usual and not as crisp, both while racing and during replays. Tried in a variety of conditions. On a positive note, night driving now looks so yummy!

They definitely changed something about the graphics. I watched a comparison video on yt yesterday and the shadows feel darker.
Could be that they improved the raytracing, but had to lower the sharpness to not lose performance, but that’s just my guess.
I was thinking the opposite l0ol. I could actually read the instruments better in my fave Porsche. I’ve been using the Digital Foundry fix adding the renderscenerio files to the ultra folder btw, and DLAA/4k. Just noticed OP/Xbox I’m speaking on PC version obviously…
Uh yeah…this is on Xbox.
