And i also find having the scenery draw distance set too high in P3d is a performance killer and have mine set too normal.Makes my sim and frames rate playable like the fellas said in the above posts fine tune your system too suit your specs.Even with my specs AMD 7950 3D cpu at 5.7 gig ,GPU 4080 and 32 gigs of ram can be put too its knees if settings are too high just saying.
