Looks like SH5 doesn't like my SLI setup

You can not make such a statement based on having only experienced SLI.
If you had tested a CrossFire setup, you would have discovered everything is shared...

I think it's more a matter of driver behavour than game supporting multi-GPUs or not.

Why do you think I told you about the scaling from one 5870 to two?
And why would I go TripleFire, when none of my games (SH (90%), GTR2, GTL) supports multiGPUs?

Latest MSI Afterburner version running for a while:

A perfectly shared load...

WOW JAN!!! did you have to do anything special to get the cards to work together in SH5???? Very strange that it would support Xfire and not SLI.

No. As said in post #6, enable A.I.

I suddenly remembered once reading something about renaming exe-files to trick nVidea into enabling SLI.

Did a search and there *may* be something in here for inspiration:

If you find a solution, I would very much like to hear it!

Wonder if we are the only two persons here on Subsim.com, that uses multiGPUs?

This is very interesting as I run a pair of 5570's crossfired and have been trying to get SH5 to run in crossfire with no success.

Jan what drivers are you using and what settings do you have enabled?

If I run with catalyst AI enabled I end up with the Black sreen bug outside the sub.

I went through a testing hell to find out, which driver to use...

Mainly play SH4 and had a strange issue with double-screen at hydrophone station.
After loads of tests - and a fresh Win7 install - I concluded drivers above Catalyst 10.9 caused this double-image.
To date this is still an issue, so I'm sticking with 10.9.

Tests showed, that the fastest driver is 11.4, but 10.9 is only marginally "slower".

Description of drivers woes: http://www.techpowerup.com/forums/sh....php?p=2177158

Settings in Catalyst Control Center:
AA 16x box
AF 16x
A.I. standard
MM HQ
V-sync on
AA Mode SSAA
OGL Triple buffer set

Re. the Black Screen Bug: try upping AA to full 16x (or 8x on a 5570?).

Thanks Jan seems like its working at the moment, no black bug outside the sub anymore.

I also had to roll back to the 10.9 drivers.

Edit: Well after downloading MSI afterburner and checking with it the load load is still not being shared over both cards.
