SLI/Crossfire Support?

[Demerzel]

Is SLI/Crossfire support on the roadmap at all?  Currently I'm getting no change in performance at all with SLI on or off with two GTX 970s, which makes it hard to run in Surround mode (5760x1200) without dropping to 20-25 fps.

Oh.. poor you some of us struggle to maintain that fps in 1920x1080

That being said I probably would gain some if it used my other gtx580. So yes. SLI support would be nice

This guy got it working for another Unity game: http://www.big-robot.com/forum/showthread.php?1890-Finally-Got-SLI-Working-But-running-into-some-minor-issues-with-V-Sync-Now

i would like this also

[Pullie]

Yes please.

+1....

any news on this?

[OlavDeng2]

as far as i am aware you have to force crossfire/sli from an external program otherwise it is not possible to do crossfire/sli in unity engine games(and this is a unity engine game)

@OlavDeng2 - This is actually not true. The people who make the Unity-engine say that their software can't see one way or the other whether SLI exists and there is no obstacle for a Unity Engine game to run perfectly well with SLI. However, there are a few caveats with the 3D rendering and especially the shaders that are caused by certain types of ways of rendering the image.

If a render directly uses information of a preceding frame then there is a big chance of SLI not giving any performance increase. On the Unity forum there are multiple explanations for programmers to get around that problem and increase performance of systems running SLI.

I do, however, understand that this is part of the optimization process that needs to be done in the final stages of programming...so we will all have to wait.

Captains, at the moment we do not know yet - there are more critical things to fix firstly.
