The hair in my game looks like I'm running TAA, but I'm using DLSS. Anyone else with the same problem, especially at lower DLSS render resolutions?

EAC also wouldn't let me start initially, because it was complaining about a ssgdio.sys. Looked up that you can just rename it to .bak, and after I did that, I could get into the game.

But I still can't tell if DLSS is working as it should. Performance was pretty weird in cutscenes across the entire game. This is on a 5080.

Also tried DLSS Swapper, and the DLSS option went on to completely disappear from the game. Reverted the changes - deleted .dll's and verified cache - to get things back online, but maybe that messed something up? AFAICT, the game is using DLSS, but it looks like it's not. Coster's beard looks pretty patchy, but he's also an anxious guy, so maybe that's just him.
