9800GX2 Woes

[Thunderbolt56]

There's a thread in the "community help" section over at UBI titled "Nvidia frustrations" that should have some possible solutions to get you to a point where you can get some terrific performance from your GPU. I had a 7950GX2 for awhile (right after they came out) and had very similar issues. Page 20-22 IIRC, of that thread discusses most of the things I did to get mine setup properly and was the result of a post by a member named Daimonsyrius.

In a nutshell, there are settings in the NV control panel as well as some line values in your IL2 conf.ini folder that should get you all set.

Sorry, I can't link that forum from work or I'd point you to the exact spot.

a couple things I know for sure:

1. Force SFR (split frame rendering) (NV control panel)
2. Set "videosetupID=x" to a value of 17.

I have a 7950 GX2.. and I have issues as well.. I have to launch the sim , get it stable, then go IP to IP in order to fly online. Otherwise it is a crap shoot as to whether or not it will lock up on me after it laods up and displays the main screen. Nothing I have figured out so far has fixed this. When I go to a single GPU it loads up.. but I loose @ 40 FPS.... I may get 65 with 2 GPUs and 25 with one... so I just suck it up and go IP to IP.. but it is a drag... and if I dont exit the mission as soon as the host ends it and shuts down.. it will lock up... None of this was happening when I had my X850.

maybe ??????

Make sure in your forgotten battles profile in the nvidia control panel you have extension limit set to off, this can prevent perfect for some reason. Also set multi-threaded optimization to off, setting to on or auto will cut frames real bad for some reason.

I have your answer! I had a heck of a time getting rid of this pulsing heartbeat studder for the longest time and I couldn't figure it out. It's not driver related its the SLI mode you're in.

I switched from the more modern Alternate Frame Rendering to the older Split Frame Rendering using nHancer and bingo it went away.

I'm using some slightly older beta drivers as well. 177.66 and I've only had a few hitches with the drivers in COD4 and sometimes playing windows media player but other than that I get the best performance in IL2 so far.
