This was posted in their discord yesterday, but I figured I'd put it up here for posterity. Looks like the AO fix got merged into mainline. Will be testing out the new anisotropic filtering setting later today.
Lookin' good! Although it looks like you're still rendering it at native 16:9, which is causing everything to look wider than it should due to everything being stretched to fit the ultrawide aspect ratio. Running this mod should fix all of that up for you π
