What to do when there's no SLI support?

[Dirk Diggler]

I've not had to deal with this for ages as most games have supported SLI really well. However, a couple are providing little or no support and I suspect might even be causing judder/stutter. If support isn't there, should I:

• Disable on an individual basis via NCP
• Disable via Nvidia Inspector
• Disable SLI and remove the bridge
• Leave it as is

I notice if I force single card via NCP then the second card can still show 20% albeit usually at a lower clock. Will this cause issues?

I would just disable in NCP and leave the bridge on. The other card is still a valid display adapter, and unless you physically remove it or disable it in device manager, I would expect it to be active in a low power mode waiting for you to plug a monitor in.

So best to disable globally rather than per game?

I would personally, it only takes 20 secs to re-enable if you want to play a game that works with SLI.

Think I am getting rid of 1 of my cards, I'm sick of the crappy SLI support!

roll on 1080Ti

I would disable per game using NCP.

Re-enabling it can be pain for me when it demands certain apps be closed first or messes up the SLI focus window

I'd say disable Sli per game and don't do a clean install on new drivers so you don't have to set it up again as I'd usually forget that mgpu was disabled needing a game restart.

Best suggestion would be junk mgpu altogether like loads of us have due to crap scaling support.

Yea, I intend to get a 1080ti but if the price is over £800 then I'd rather just work with what I have as I'm sick of the stupid pricing strategy right now.

EDIT: I've disabled SLI altogether globally as it guarantees the 2nd card is at 0% at therefore not interfering. I think there'll be another 980ti in the MM soon as I think I'll have to admit my SLI stop-gap isn't really cutting it.
