Screen flicker prob in SLI mode - FS9 & FSX

[bbstackerf]

I have a couple of 8600 cards in my desk top - P5N-E Asus MoBo. Vista Home Pre 32-bit with an X-52 control set up and a Cyborg Keyboard, . When I run with a single card I can use all res modes in both FS9 and FSX. But as soon as I switch to SLI mode and run both cards I can't get either sim to run in anything higher than 1024x786 without have wild screen flicker continuously. Intrestingly, if I use the hat switch to look down on the a/c from a high angle the flicker stops. The minute I angle down anywhere close to being on an even view or have the view show surrounding scenery the flicker starts again. Is there a setting I'm missing here?

Neither FS9 or FSX use SLi for performance increase.. you are wasting your resources on 2 cards

The onlt benefit FS9 or FSX will have with SLi is IF the monitor resolution is higher than 2000x AND you run 16-32AA. In that case you are able to run that resolution and AA without a massive perf loss but below those resolutions and AA settings, not one frame more and SLi is actually hitting the system harder

there is absolutely not, nadda, nothing in performace gained with Sli  in MSFS

Got it. So basically I should just keep my system on single card mode. Thanx for the info I should have asked a long time ago.

Yep

single card in FSX unless you are running a massive resolution and want the high AA support

and even then, you would be hard pressed to notice the difference between 1920x1200 8xS (single card) and 25xxx 16AA Sli

But is most games that use the GPU allot, SLi can be helpful

Hmm - I get horizontal flickers too.
