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

That is my next task!

Last night I successfully updated my Nvidia 280.26 driver to the beta 285.27 driver because I was seeing favourable report re SLI. I also used Rick's SLI profile suggestion he posted in another thread which appears to have slightly increased the gpu workload from 45% - 50% to now about 45% - 60/65% (higher over land, less over sea). This is still with my 1680 x 1050 Samsung monitor. (I've been using this monitor as MAIN because it's "3D-ready at 120 MHz" - but it crashes CoD unless I set it to 60 MHz. I needed Fearless Frog's help to reset the freq back to 60 in Softclub's config.ini because the stupid screen was blacked out. Also, I use this screen for video editing chores which is mainly why I've been so slow to switch over to my larger screen at present. Very soon though.)

EDIT: Just switched over to the larger monitor and increased resolution in the C0D video menu to 1920 x 1080 from the previous 1680 x 1050 of the smaller monitor. Fired up C0D and went to Free Flight over England for a quick check, with, as usual, the Precision EVGA utility runnin on the 2nd monitor to keep an eye on GPU performance. Right away I noticed an increase in GPU workload, from the previous 45% - 65% to the now 55% - 90% (depending if I was looking up at the sky (low workload) or the ground while flying at low altitude (high workload)). Fan speed (which is set automatically to increase as temperature rises) immediately kicked in higher but temps remained moderately high at 60 - 70 C (the card placed over the lower one tends to run about 10 C higher). Frame rates were actually better with the larger screen, staying closer to 60 fps with less variance downwards. Perhaps the with the cards working harder they're working more efficiently as well. There remains some slight stuttering with low level flying over landscape. I need to do more flying under various high-load conditions (lots of planes in combat, lots of clouds, lots of explosions, etc.) to really get a feel. Plus I haven't run the single card with the larger monitor, but I don't really intend to muck about any further. I'm hoping that 1C release a specific SLI profile for C0D soon -- perhaps when this beta goes to gold -- to see if greater performance can be achieved.

I do believe Hurricanedriver should try the SLI with Russ' suggested settings in Nvidia Inspector -- hate to leave him hanging from his original post.

How's that done, Snapper? Can you give us a bit of a tutorial?

Edit - Just looked at RickRuski's thread. Edited my profile! Thanks guys.

Great! Let us know how you got on. Rick has done some fantastic work here - quite painstaking to see what works and what doesn't.

When (not if) 1C comes out with a SLI profile for its eventually-optimized code it'll be interesting to see how it compares to Rick's suggestions.

With all of the settings tweaked, I can see by EVGA Precision that both cards are sharing the load. FSX is the smoothest it's ever been, and COD is looking pretty good too. Fantastic work!
