Anyone have any luck forcing DLSS4.0 on Rebirth?

I updated to the latest Nvidia App, also updated to the latest driver (572.16) and I tested it with other games (Marvel Rivals, Lies of P and it seems to work)

I'm also on an RTX3080

However, found a number of strange issues specifically with FFVII Rebirth:

• It isn't automatically added to the list of games
• I tried adding the specific game folder and refreshed/rescanned, still nothing
• Adding the .exe manually (I tried it on both the one in the folder, and the one in the game folder and the one in End/Binaries/Win64), and for both it shows "Program does not support optimization” which is a first for me (NEVER seen this before)
• on DLSS override specifically, it says "Support not detected" BUT I can still click it (and on games that DONT have DLSS it says "Unsupported") so this is really strange
• I can try to click "Latest" but though I can confirm it, it changes for a split second THEN reverts to "Support not Detected"

I don't really know what else to do here. Anyone getting the same?
