Enable SLI for Batman Arkham City?

[imaheadcase]

I'm new to the SLI game, but i can't seem to find any way to enable SLI for this game. The only profile i see is for Asylum, but that does not work. For 2xgtx580.

How do i get it to work with the game? My google search turned up empty Its prob something simple since no one else is having issues..lol

Your SLI settings are set in your nVidia control panel, not in games. (AFAIK)

Yah i know, its not detected, or can't make it work from it from custom profile.

no your lost in how sli works....

If your Nvidia control panel says Maximize 3D Performance (SLI Enabled)... all 3D applications u run though it will be in SLI.

For you to run the game off SLI, it would need to say Disable SLI.

You see how in my control pannel is says SLI.. it means ANY game i run regardless of what it is will run in SLI...

For me to run the game off SLI, i need to disable SLI though the control panel.

if your asking where that option is..

Left mouse click on desktop -> Nvidia control panel -> Configure SLI , PhysX, Surround in the 3D settings tab.

That is the exact opposite of how i got sli to work with bf3. My only option is Enable SLI, in control panel for bf3.

Why would you disable sli to run sli..?:/ So disable it makes batman run..i'll try that.

SLI is a global setting, in nVidia control panel... not sure what you're saying here.

SLI is global... there shouldnt be an option INSIDE A GAME to enable or disable SLI.
Are you talking about the multi core option? That relates to the CPU processor, not the video cards.

its in the control panel, so yes were really lost in what your trying to say.

If you disable SLI in global... then SLI is turned off for everything.
If you enable SLI, then its on for everything that has a 3d application.
Even in windowed mode.. if its a 3d application with sli on, your SLI will work.

Your drivers handle the scaling of the game... not the game itself.

I know all that. I'm just saying it does not work in the game. Its not hard to understand.

How do you know it's not working in game?

I found the answer, apparently you have to alt-tab it and restore it for it to start working with game, known bug. Looks good to me

I can confirm that bug does exist. Hitting ALT+ENTER twice during the start up screen does increase performance substantially on SLi rigs.
