SLI Flickering..nothing working?

[SLI Flickering..nothing working?]

i HAD the same, i was experimenting with my mobo´s integrated GPU, to dedicate it to physX, and i remember that i put physx and sli markers visible from nvidia CP, to see if it works, and when i first launched the game it started. I then rebooted and i think the reboot fixed it.

Goddamn i cant remember well what configuration i had in bios and nvidia CP.

Though i got it to work with integrated + 2x9600GT in sli.

I think it might be driver issue. Clean all tracks of your drivers, uninstall them properly, clear all GPU´s from your device manager, and install them again. It might work. Check your sli-marker status from nvidia CP and so on.

[ArmaHolic ArmA 2 Optimization]

Arma2 settings:

1680x1050 with:

visibility: 2061

texture detail: high

video mem: high (tried it with default with no noticeable change)

anisotropic: normal

Antialiasing: low

terrain: normal

objects: normal

shadows: very high

postprocess: disabled

I have windows 7 with

9600GT SLI

4gb of 1024MHz ddr2 (ganged)

250 gb hdd with 32mb cache

AMD Phenom2 x2 550 BE

ASUS m3n-ht deluxe mobo

cpu slightly Oc´d (200-->203 or smthng), temperatures doesnt go above 55-65 celsius.

(at the moment i use for phys-x my mobo´s integrated nvidia 8400 something (or was it 8200) GPU)

I´m getting mostly 20-25 fps, 1.05 patch make it somewhat better, but still not satisfactory.

I´m not sure are these settings supposed to give my system this FPS, i have tried to tweak it, change settings etc..

Is there something wrong? Should i get more FPS? If so, any semi-pro or pro guess of "youshouldofhave-FPS" are welcome.

noobie-thanks for all interested answering :)
