Hi,
Few weeks ago i bought a new PC : I5 3570K, gtx 660, 128go ssd, 1600 mhz ram (2x4 go) ...
So i took my time to configure FSX, i made so many tests with fsx cfg and nvidia inspector, and finally chosen my preferred settings.
Briefly: poolsize=0, 8xs antialias and 2x transparency supersampling, adaptativ vsync + 1/2 refresh rate. FPS limited to 30 with nvidia and unlimited IG.
and some other tweaks of Word Not Allowed's guide and nvidia inspector on pmdg forum.
So everything is ok i have constant 30 FPS and very very few stuttering/micro freeze, but in aerosoft paris CDG i drop to 10-12 FPS in the ngx cockpit and 15 to 25 outside. I have 100% traffic with My Traffic X but this addon has very simple traffic and doesn't affect my FPS ( i've tested)
Then i overlocked to 4,4 ghz (+30%), i hoped to go up to 15 FPS in cockpit but nothing changed... Am i Gpu limited or i didn't OC well ?
(sorry for my english!)
