EVGA GTX260

[Ferrari308guy]

I just upgraded my system. I upgraded my motherboard to a Nvidia 780i, and I upgraded my video card from a Nvidia 8600GT to an EVGA GTX260. Once I got everything set up, I installed the drivers for both products, and started FSX. My performance is worse than before! Any suggestions? Beyond getting the most recent drivers, I'm not sure what to do. I've heard that the CPU could be holding the video card back in a sense. But I would expect that I would at least get as good performance as before. I have FSX on medium settings, and I can run the default aircraft fine...but it's the add-ons that I have issues with. my goal is to get the VC of the Level D running at around 20FPS, right now I can't get past 10. I have the normal FSX.cfg tweaks put in, and I'm still not getting good performance. Based on my specs, is this the performance I should be getting? I would think it would be higher. Would overclocking do anything? I would need some help there, as I would have no idea what I'm doing.

Specs:
EVGA GTX260
3GB RAM
Nvidia 780i Mobo
Processor 820 2.8Ghz RAM

Any suggestions?

when you upgrade motherboards you should always reinstall the OS because that itself could cause huge perf problems

Yes, I wiped my hard drive and installed a clean version of Vista.  :)

Hi,

When I upgraded to a GTX 260, I found that the latest 180 series of drivers did not get on with FSX at all.

I went back to the 177.92 drivers and all was well ! I also found that 4 GB of physical memory made FSX weep.........it was not happy...n/b I am on XP professional.

I suggest changing drivers away from 180's. For some reason the 180's with the GTX 260 and FSX were not happy on my system. No harm trying that first !

Don't forget to uninstall properly using 'Driver Cleaner Pro' (in Safe Mode AFTER uninstaling nVidia normally and rebooting) and then reinstalling DirectX 9 last of all.

Given that you're using the new Nehalem stuff...you are entering unfamiliar territory, but I'm sure Nick and his cronies will steer you in the right direction.

PS. make sure that if you use nHancer, use it properly. See all the posts on this.....unless you are happy with the default in-game settings.

I found that not having nHancer setup properly (ie. ensuring the Profile for FSX is setup and agrees exactly with the Global settings) also caused BSODS ! Never a problem with my 8800GTS but it surely was with the new 260 !
