Just installed another GTX 460 in SLI - at last I can fly properly

Please HurricaneDriver try disabling sli and post your conclusions

It's seems so that I'm running COD on one card. The largest hardware change I've made is removing my Audigy sound card to make room for the second vidcard. I'm using onboard sound now so maybe that's where I'm getting the extra system speed.....

I've disabled SLI and retested. There appears to be a slight FPS hit, but I definitely am running on one card. Whatever, COD runs much better without the Audigy software/hardware. Really looking forward to SLI being enabled by the devs - it really should improve FPS.

Ok, so please everybody here vote and comment on the "nvidia profile/sli compatibility patch request" thread:

thank you

I have 2 GTX 480s configured in SLI. I tried enabling SLI in CoD via NNVIDA Inspector and it was a mess so I'm back to running CoD in single GPU mode. Even in single GPU mode I do see some activity on the second card. It isn't much varying from 0 to about 10% +-. I have a second monitor where I can watch Precision, etc. while flying. I don't see any activity on that card when I'm not flying in CoD (or some actual SLI ready app.). In there some PhysX in this game????

I'm noticing about a 10%-15% improvement with SLI enabled, too. Having SLI at this stage just improves performance just that little bit much, so I'm leaving it on as it makes TrackIR a little smoother. Wonder when the devs will look at supporting SLI?

Done!

Even though I have SLI working with a Custom Profile (tweaking Nvidia Inspector), surely the smart guys at Nvidia working with the 1C devs will come up with an even better profile giving even better performance.

I use this free utility which tells me exactly what's going on with my two video cards:

http://www.evga.com/precision/default.asp

Before I assigned a Custom Profile to CoD one of the GTX 560 Ti cards was doing about 90% of the work (and running a high temp) and the 2nd card was loafing along at 10% and a low temp. With the Custom Profile they're now sharing the workload evenly with moderate temperature rises roughly equal (the upper card runs about 10 C warmer).

This utility also enables you to program the video card fans to automatically increase in speed (for better cooling) as the cards' workload increases.
