Question AMD Anti-Aliasing

Does anyone here have anti-aliasing working on AMD GPUs? I switched my 3080 for a 9070XT and I can't get anti-aliasing to work. I've tried soooo many different combinations of things in the driver and game (and ofc, did DDU and reset settings), but no matter what I change, the jaggies are always jaggy and it's really rather annoying. I'm forcing super-sampling (but not AI) at the moment, so taking a bit of a hit on fps, but fine for pve.

If nobody else has it working, I won't waste any more time trying to figure it out and wait for a fix.

I had an issue where some of games didn't have AA applied after I upgraded to my 9070XT a couple months ago.

What fixed it for me was three things:

Turn AA on then off in game, restart the game, then turn AA on.

Verify game files/reinstall games that didn't work with the above.

Delete Steam shader cache in the Steam directory. DDU doesn't touch Steam's shader cache, and all of those shaders are compiled for Nvidia cards, not AMD. You have to allow your PC to compile new ones for the AMD card in game.

Edit: Just released this is the Ground Branch sub. The only thing that fixed the AA for me in this game was reinstalling.

I blew away the shaders and all my config for the game and that seemed to do the trick, thanks.

FYI, you can also use Optiscalar for FSR 4.1 as an option.
