I run windows XP home 32 bit using Nvidia GeForce GTX 260 896 MB graphic card,with new drivers 296.10, 3 1/4 GB memory ( max mem for XP 32 bit.
I did run a AMD Phenom 9500 X4 processor 2.2GHz.at 4.0 MB Cache, I could get 50, sometimes 70 FPS in the sky with some clouds at maybe 20,000 ft with sliders almost all maxed except for Airliners and GA's and some of the terrain sliders were only about 70/80%. I did have problems in very large airports with down to maybe 12/20 fps. Well Airports like KJFK I'd just weep and get out of there. LOL
Well I got greedy and installed the biggest Quad ( Knowing FSX hates Quads ) processor I could find that would fit my motherboard. It's an AMD Phenom II Black Edition X4 965 at 3.4GHz for each core with 8.0 MB total Cache where the other one was just 2.2GHz at 4.0 MB total Cache.
GROAN I now can only get maybe 15 FPS max and that's on the ground in a blurred field with no obstacles near ( like trees or bldgs.
I don't dare go to just a small airport with planes or no planes and the FPS are 5 maybe 8 FPS.
The default in settings are mostly all 0% for the sliders, only a couple sliders with 25 maybe 30%. I can get 25/30 FPS using default but the scenery is so blurred ( so is aircraft ) that it makes me sick ( no joke ).
The processor checks out to be good and a couple games I have ( different publishers than MS ) have VERY high graphics and this processor will beat the fool out of the game compared to the older 2.2GHz processor. No its not that the processor is bad I'm pretty sure for if it was I'd think the other games would be affected also.
I tried "search" but could not find what I think is some D/L that tweeks FSX Simulation. Can anyone point me to this fix?
