Tested this on a dummy file and i'm getting the same issues, images attached below.
So I just built a new PC and started working in substance again only to realize some of my bakes are completely broken. AO in particular has these weird artifacts appearing all over the model. The model and UVs are fine and my GPU drivers are updated to latest. At my wits end trying to fix this. PC spec is 7600x3d and 7900xtx with 32 gigs of ram. Windows 11. I'm using Substance Painter 2022 Steam Edition.
