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

Actually Snapper for me its not, it runs alot smoother with one card and I was asking HurricaneDriver what he did to make it work.

With TrackIR COD was pretty unpleasant until I installed my second card yesterday. The whole game is so much smoother, and all I did was enable SLI in Nvidia properties. SLI must be working. ROF is also that much better (I did manually enable SLI in ROF though). Not sure - but SLI seems to be working. Sorry, don't feel like mucking around with FPS counts, but I've found if a sim runs smoothly it greatly adds to the immersion, and I pretty much have 95% of that now, whereas I had 70% before the upgrade.

HurricaneDriver if that's all you did SLI isn't working in COD, no joke. Your second card its doing nothing. Its been broken for some time and needs fixing. You can force it to work(see Snappers post) but thats the only way. Most of us find it runs smoother with one card but you can try it and see.

Yes SLI do work with ROF.

Just enable the SLI indicator in the Nvidia control panel or check your FPS.

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:

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

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.
