HI, im just getting back into fs9 after buying a new system which is as follows...intel core2duo E6600 1066fsb 4mb 2g ddrati x1600senow the sim runs really well on the whole and with all sliders maxed, 1440x900 resolution, 4x AA and AF, active sky 6, ground environment pro, ultimate terrain, ultimate traffic and the levelD767, im getting a good consistent 25+fps. the only problem is that when there are any clouds present the framerates drop to the mid teens. this happens whether ive got 2 clouds in the sky or full overcast conditions. lowering the amount of cloud coverage has no impact nor does using active sky to reduce the cloud size to even 64x64 and dxt3 format.the only reason for this i can think of is some sort of confliction with my particular gpu, which i know isnt the best out there, but then i never had this problem with my old fx5600. hmmmany ideas or suggestions would be much appreciated.

Dear Triple-Retard; This is the second post I've seen today from an ex-nVidia user seeing a perf problem after moving to a mid-range ATI card. Check your fs9.cfg to make sure there isn't still a DISPLAY.device line for the nVidia card. You can also try reducing the number of layers in ActiveSky, and reducing the cloud draw distance in FS. And remember...ATI is the devil... :-wink2CheersBob ScottATP IMEL Gulfstream II-III-IV-VSantiago de Chile
