Hi Flappie,
I disabled "Enhanced Sync" both at Global and DCS profile within the Radeon settings, deleted the fxo and the metashaders2 folders again, started the game, flew the same mission as before (Syria map, Su-33). More than 1 hour later I finished the mission by landing on the Kuznetsov with the last drop of fuel, folded the wings, rolled to the parking position and ... crash! Very frustrating.
Attached you can find the dcs.log and the dxdiag.txt (the .trk file is to large for upload).
Best regards,
René dcs.20201031-100926.log dxdiag.txt
