Hello fellow simmers,I decided to upgrade my C2D 8500/3.8Ghz OC/8800GTX/768 in steps and the first one was buying a Corsair 128Gb SSD extreme which gave me satisfying overall results and have now FS9.1 dedicated running on the former OS drive, my old VeloRaptor 300Gb. When the prices are further dropping I want to give FS9.1 her own SSD card, what an amazing performance increase compare to the Raptor as OS drive.Because I had the feeling that the

Delete your fs9.cfg file and restart FS9. This will automatically recreate that file. You'll need to reconfigure your graphical and other program settings after that but 9 times out of 10 after a graphics card change this will resolve any issues. If it doesn't, you'll want to uninstall and reinstall the nvidia driver.

Thanks for the input, I've build up the CFG again. (I already deinstalled and installed the driver before testing) and is giving me no more FSP but it seemed to me that the flight is smoother. I have to check it again when flying online and see what is happening. (Flying online with FSINN cost me always a 10FPS) Flying off line and fps locked at 30 it looks steady now.Maybe you can answer the next question, What is the most critical part of a PC running FS9 for building up the scenery textures? What I mean is, you can always see pop up the next radius/ring within the scenery. It's became better ofcourse over the years with the modern and faster computers but still you can see it.Is there a way to solve that last little anoying thing in FS9 to make it a perfect sim?Thx...

I upgraded from the 8600 to the gtx 260. I installed the latest drivers and my performance dropped also. I went to an older driver and presto! the performance and frame rate trippled!! I read on other forum post, that the new drivers from nvidia were crap.

You can increase your processing speed and I/O throughput to achieve faster texture loading. IOW: get a faster CPU (or overclock) and/or get faster hard drive(s) and RAM.

Well I deinstalled the 195.62 WQHL drivers, used driversweep to clean up, installed the 191.07 from the Asus cd-rom but have the same result. In unlimited mode max 60 FPS with drop downs in heavy scenery to 20 FPS, I reached with the old 8800GTX the same results. The overall flight is a bit smoother but not what I expected for a card with double the specs...I optimized my 1066 DDR2 ram and OC the E8500 to 4 Ghz but only minor improvement.I think I will bring the card back to the shop and try a ATI card Thanks anyway for the tip.

Sounds more like a botched install than anything else.I

FS9 is not GPU-limited with an 8800 GTX, therefore your results are precisely as they should be. If you want better performance from a graphics card upgrade, you would already need to be running insanely high graphical settings to even remotely stress the graphics card. Example: running 2560x1600 resolution with 16x AA and every add-on known to man may just start to touch the GPU's ability. IOW: you want more performance, you need a faster CPU.

In Other Words

If you buy ATI, choose the latest and fastest. Older ones like the 4850 die when clouds come into the equation. This halfes frame rates.
