After too many hours spent getting this thing to work I am giving up for now till I can afford a new system.
System specs are a little dated but only have problems with Microsoft Flight Sim 2020. Running Windows Pro edition, Intel i-5 6600k running at 3.5, 16 gig DDR3 and Nvidia GTX1060 6gb.
Game starts out ok with 35 to 40fps then after a couple of minutes cycles between 2 to 30 fps making it useless to try and fly. I have set everything to low turned off airplanes , cars boats ect. done all the recommended settings to no real avail. Will be going back to X-Plane 11 which runs with no problems.
