Do you think it relates with GPU mem? My GPU is 3080Ti (12G mem), and yours' 3090(24G mem). AH64D cost GPU mem too much, it could explain why only AH64D lost FPS on my side.
OK, I removed my mods, then remove the tacview line in the Export.Lua, and run a repair(slow).
Retested it, got the Log file.
Here you are, pls check it.
Thanks

Almost same, mine is i7-12700K cpu + 3080Ti GPU. In 2D mode, it's showing GPU bound(green), in VR mode it's showing CPU bound(yellow and red). I'm comfused, I thought it should cost more GPU in VR mode, but why it's CPU bound?
