I had the exact same thing after the last BF6 patch (RX 6800 XT, Win11). What helped me was a clean driver reinstall use DDU in safe mode to remove everything, then install an older “stable” AMD package (the one from before the patch) not the bleeding-edge hotfix. Also do these in order: verify game files (EA app/Steam), disable any overlays (Discord/GeForce Now/Steam overlay), turn off Radeon features like Chill / Anti-Lag / Super Resolution, and set Windows power plan to High Performance. If you still see driver resets, check Event Viewer for GPU/driver errors and consider increasing TdrDelay in the registry (back up first) that can stop Windows from killing the driver during a long hitch. No single magic bullet, but the DDU → older driver → disable overlays combo fixed it for me.
