Lack of improvement in sli? - Page 2

post #11 of 20
Console ports do not work with SLI (forthemostpart). I'd expect worse performance with SLI.

So, when you're actually running the game and monitoring clocks, the 2nd card stays at 51MHz (normal desktop/2d clocks)? If you go to NVCP and look at the list of *all* the game profiles (uncheck the box for 'only games on this pc') that the driver has, do you see Dead Island? If it's not there, that's a pretty certain sign that the drivers you're running lack an SLI profile for this particular game. I would try the latest beta drivers available and/or the latest SLI enhancement pack (if there is one newer than the latest drivers).

If the profile is still not there, you either have to wait for nV to add it, or try one of the 'tricks' for achieving SLI support w/o a proper profile.

Sorry, but this is utter poppycock

This issue has to do w/how new the game is, and nothing to do w/it being a console port. I've played many dozens of different console ports where SLI works perfectly.

If what you say were true, nobody would run SLI ... seeing as how like 80% of all PC games nowadays are console ports

Well, there it is then.

SLI enhancement packs exist to add SLI support for new games, in between formal driver releases.

OP, you should grab this from evga (it'll work w/any brand of cards) and install it ... then you should find that both cards crank up to full 3d clocks, and your perf should be enhanced significantly

I also think I found my Maine problem. I have been gaming on this pretty old 19" LCD monitor and whenever I put it on my hd tv it is tons smoother. I think I should probably invest in a hd 19"-23" monitor. Do you think that's a big problem?

I don't think so. I always thought that lower resolutions ends in really high performance.

There are games that are badly optimized for SLI, or that add support later. Just make sure that you got the latest drivers (266.58 have never given me any issues on SLI tho they're not the latest ones) and if you play games with SLI issues, try the EVGA SLI Enhancement Packs. They worked with my MSI cards.

I'd also try and reinstall the drivers, making sure to perform a clean install, then re-enabling SLI on the Nvidia Control Panel.

Your i5 is enough to rock most games, and 450 SLI are no slouches. Hell, we practically got the same rigs and i can play SC2, BF2, BF3 (beta) and other games.
