I have the EVGA 8800GT 512 and I was getting better perf and IQ with my 7900KO.It seems this new card does not keep up with the scenery as fast....If I am in spot view the texture looks blurry until it renders but my old card seems to always have the rendered scenery instantly without any lag this includesd AI sitting at a gate and looking from my 2d cockpit left or right and the AI will need to fill in as well and after some time it needs to do it again so the GPU memory is not being utilized correctly within the SIM.I have tried the following drivers 169.21,169.02,169.09 and so far have stuck with the 169.04.Tried with and w/o NHANCERAF=16AA=8XQ with supersampling tried multi and none as wellAa mode=Override any application settigVSync=offneg LOD bias=clampTexture quality=High

That's dissapointing.....I'm in line to upgrade from my 6800XT 256mbTheres gotta be a driver conflict, did you uninstall the old drivers before installing the new card+drivers?

As Ryan mentions, this smells much more like drivers or some other fouled item, rather than the card and its performance.I too updated from a 7900 to a 8800 GT, but my experience has been anything BUT negative. Getting all around better performance in FSX, as well as many of the other games I play.When you were swapping drivers, did you do a full wipe of the drivers on your system? If not, give it a shot - maybe even pick up a driver cleaner utility to purge it all - then reload the latest ones. You may also wish to backup then delete your fsx.cfg file to let it be rebuilt. The config file often sets up some values based on the card installed, and maybe it's causing a hitch as well. Hopefully you can get it working - and Ryan, do note that there are many more success stories than failures with the card. It's a pretty safe bet. :)Good luck!-Greg

There is no way you should have a performance decrease going from 7900 series card to 8800 series card. As stated above you have issues elsewhere. More than likely I would suspect an Nvidia driver conflict (remnants left over from a previously installed driver). Go to your control panel and remove your Nvidia display drivers, reboot into safe mode and use a driver cleaning utiltiy to completely remove all Nvidia display driver registry entries and remaining files, boot back into your OS and install the latest drivers.I happen to use Driver Cleaner.net which is a modest $10. There are also freeware solutions available.

Not to be too modest but I have installed and removed about 1000 ATI and NVIDIA drivers in my day and I usually remove using CP and reboot into safe mode then I use driver cleaner3 and driver sweeper and on top of that a full reg mechanic cleanup.I reboot again in XP and install new driver .....BTW I am running FS9 SP1 and yes I agree performance is great but the rendering time or the GPU RAM is not being utilized correctly.What drivers are u guys using BTW and all systems are different so what one might find great another could be sub par.I use ASV with unlimited levels of clouds and it looks great.Fly say at FL250 using PMDG and go into spot view and look down at the ground or slightly in the distance and tell me if your card is rendering the scenery instantly or is it playing catch up.ThanksAndy

Well I did some more research outside AVSIM and I ran RivaTuner and lowered my GPU Memory Clock to ~875 from 950 and I increased the GPU fan ~ 60% and whola all issues related to rendering are gone.Just did a quickie from KSEA-KPDX using the F1 ATR and the scenery at FL120 was spectacular and there was no rendering at all what I saw was already loaded by the time I switched views.I have read there are some faulty GPU RAM out there and I might be one of the unfortunate ones but by lowering the RAM clock cycle it helped a world of difference.Andy

There ya' go!I'm sure we all weren't looking down on you for the driver uninstall thing... it's just the most likely scenario that wasn't explicitly mentioned in your original post, thats all. Glad to see you're back on track. -Greg

have you read this: http://forums.avsim.net/dcboard.php?az=sho...id=430970&page=It made all the difference in the world for me. Good luck.

Good to know, I'm getting an 8800 GT, and I've uninstalled all of my old nVidia drivers from my old GeForce4 MX 440, I hope it will work out well.

OK well after reading the Guru thread, I don't think this is my issue. My card is working fine.I have made the changes using Nhancer and yes it has helped a lot but still not perfect. I might try Clamp setting of -1 and see if that gets rid of the last bit of shimmers.Mark.
