Alright I just did a flight and the frames were where i would expect, EXCEPT when the mouse pointer was in the fs screen. I tested this over and over again. As soon as the mouse moves in the fs gameplay screen the frames drop alot they were in the 30-45 range sometimes in the 50's on the ground without the mouse in view, put the mouse in view the fps would drop to about 21-28, put the mouse away and boom instant fps boost into the 40's area. Cruising the same thing, mouse pointer in view fps drop. Without the mouse my average fps was 42-56 but they would move into the 60s as well. Sounds like a driver thing?

Btw i am also getting a tearing as if the frames were above my monitors refresh rate, the refresh rate is 75, even if i lock the frames at 65 it still happens. And yes vsync is enabled.

Hello again, just got trackir4, now the fps are low again 20's and 30's dipping in the teens when fs neeeds to load a texture or something. This si really becoming fustrating ive worked so hard on this pc to get high fps and i hear of people with similar specs rejoicing about frames in the 50's and 60's continuously and here i am in the 20's. could it be the terrain mesh, I mean im really running out of ideas now!

Mike; Do you have threaded optimization turned on in your video driver 3D settings?RegardsBob ScottATP IMEL Gulfstream II-III-IV-VSantiago de Chile

nope

OK...try turning it on and see if that helps.CheersBob ScottATP IMEL Gulfstream II-III-IV-VSantiago de Chile

Alright, One other thing I have done some research and have noticed that when im cruising the frames are between 40-60 but they drop to the 40's lower to the ground, and when a texture is being loaded from low res to high, and elevation detail changes to a more detailed one the fps drop to about 18 and lower, but then return to the 30's and maybe 40. Is this normal yet?
