First of all…I apologize for being a little snippy, this is SO frustrating. I appreciate all your ideas and desire to help.
So I’ve been messing around with things some more, finally gained access to the .EXE file, and under Compatibility, I checked the box to Disable Full Screen Optimizations. Fired up the sim again and there was a marked improvement. 20-30 FPS now, but still extremely stuttering compared to prior experience. But I can get off the ground and maintain a trajectory at least.
EDIT: Other games have been fine, nothing bad. Assetto Corsa is probably the only other graphics-intensive game I play, which is a far cry from FS2020, but AC gives me consistent 100+ FPS.
Here are my FS graphics settings…I will keep playing around with these but please do suggest changes. I’ll also be getting my screwdriver out to remove the 8GB RAM stick later today.
