Both the 460's temps increased, showing they were both working. For some reason the Crysis Benchmark tool isn't working, so I can't do that.
Whoa ... yeah. You've got a problem. That's in 'Performance' mode? 3503 is barely what a single 460 should get in Perf mode
You should activate the onscreen display in Afterburner, have it show all your stats while running tests/gaming, etc.
Make sure not only are temps going up on both, but clocks are properly kicking up to full 3d clocks when gaming (675 core iirc on a 460), and that your gpu usage is up around 90% plus (esp. when running benchies).
Also make sure v-sync isn't capping you at 60fps when you're doing testing (personally I always use it to game, but it can severely hobble you on benchmarks). In fact, make sure everything in NVCP is restored to default values.
Try/check all those things, and do another run on 3dMark11. Something is amiss somewhere, and there's a good chance that somewhere in the AB graphs you're going to find the answer. Before you do the run, detach the graphs window from the AB app, and stretch it to full height of the screen, and make sure EVERYTHING is 'enabled' ... so you can 'see' ALL the stats being generated. Then take a screenie with the graphs right after running 3dMark11 and post it.
We want to see core clocks, gpu usage, and temps (all these on both cards) in particular.
Or, if you're running Extreme mode ... then that score might be perfectly alright ... dunno cause I don't have full version
I could see having an issue w/running Metro maxed out at 1920x1200, at least w/lag in certain parts of the game. At 1920x1200 maxed out Metro will eat up upwards of 1GB of vram very easily. I used to have 5850's in Crossfire (very comparable to 460's) and I ended up having to play Metro on High w/no AA if I didn't want to ever have any noticeable lag (i.e. never dropping below about 50fps).
One thing you should DEFINITELY turn off in Metro is ADoF. It's a HUGE frame killer, and doesn't even look that cool. You could likely get away w/Very High as long as you turn off ADoF (and advanced physX off might be needed as well ... and forget 4xMSAA cause that uses mad vram).
EDIT: In general you'll want to keep an eye on vram usage with those cards. 1920x1200 is a lot of pixels to push with only 1GB capacity.Edited by brettjv - 8/8/11 at 9:17am
