For some reason it doesn't seem to be using SLI. My GPU 1 is running at the normal higher game temps (70c) and GPU 2 is not doing anything over normal (40c). Is there a way to enable in-game that I am missing?

i had that issue too, i searched google for a crysis 2 sli enhancement from nvidia i believe....

it enable sli but it isnt an official sli profile

and just be forewarned you will see some weird flickering with it, but it will allow sli in crysis 2

The thing you are talking about is the EVGA SLI enhancement

The game just came out today. You have to wait a few days usually for SLI patch. The patch mentioned above is for the demo only. Thats the thing with SLI, without proper coding its useless. Luckily I have 2 570gtxs, so 1 is plenty enough for 70fps on extreme

I also have 2 GTX570's and m getting roughly 90-150 fps in the custom maps. God forbid we actually get to **** rank up... This is what I get for pre-ordering.... Its like pre-ejaculating, no fun!

The patch mentioned above is for the demo only.
It works on both... im running 480 SLI fine

me too all good on 480 sli..though I do notice some slight flickering but not always
