Got sli to work!

[timmy762]

there is hope until nvidia adds an sli profile for clod.
Have tried since release to get sli working to no avail. just tried after last patch using nvidia inspector and added launcher.exe to the profile for Battlefield bad company 2 and wala! getting some great results with pseudo mode 1920x1200 on my gtx260 sli core 2 quad q9550 rig. no activity on second card in full screen mode though, but we have to start somewhere right

Could you measure a performance increase with some track like the black death?

[timmy762]

ok did some fraps testing with the black death track settings attached:
sli disabled
Frames, Time (ms), Min, Max, Avg
6036, 222192, 7, 79, 27.166

sli enabled
Frames, Time (ms), Min, Max, Avg
8383, 222130, 10, 89, 37.739

worked for me but too much water texture corruption to use
black death increased from 35 av to 57 av @1920 x 1080 @ 120Mhz
promising indeed
thanks for info timmy

edit : proper full screen
edit 2 : interesting, changed to pseudo-full screen and got same fps with cured water problem. Nice.

[timmy762]

i found the same corruption with full mode got smoother results with pseudo. i know we have to wait for a proper sli profile but seems something still isnt right with full screen as luthier keeps saying

Working SLI-Bits to edit with nvidia inspector.

Create custom profile and add launcher.exe.

edit:
SLI compatibility bits (DX10): 0x000000F5
&
NVIDIA predefined SLI mode on DirectX 10: SLI_PREREFINED_MODE_DX10_FORCE_AFR

I get 99% usage on both GPUs in most of the scenes, cockpit view however seems broken and I get about 1/4FPS of external view and some flickering.

Driver used: 275.27 Beta / Win7 64

Sys used:
Intel Core i7 930 @ 4.2Ghz
Asus Rampage III Extreme
12GB Corsair Dominator GT 1600Mhz
2x Geforce GTX580 SLI @ 850Mhz
Creative X-Fi Titanium HD
Dell U2711 2560x1440


and it worked perfectly :)

But I see my GPUs seriously overheating.... 88°C :angry2:

Great news!

But what on earth is a "wala"? It almost sounds like you're trying to say the French word "voila". ;)

[timmy762]

yes "voila" i was in a rush... however good to see people having a play. although the sli bits forced to afr seems more logical i found afr3 smoother. cant wait for another driver release and an official profile.
