Have to say, there is definitely an improvement after SU5. I’ve got some CTDs after update (mainly world map and while loading), but not a single one WHILE flying in VR.
Now I also fly airliner in VR, because of the performance improvements I get a higher usable render resolution (100 now) and it’s no problem to read the instruments. Pretty nice experience now.
IMHO I think it’s just a nice “side effect” of SU5, not a specific fix for the G2 or AMD GPUs… but it seem to work.
