Hi all,I'm using an ATI HD5970 card and currently on driver version 11.6.I have noticed that while running FSX, my GPU 1 almost maxes out while GPU 2 remains at zero. I've tried running other applications and both my GPUs were being utilized. So for some reason, crossfire refuses to run with FSX. I was wondering how I can fix this problem?I don't have an "enable crossfire" option on my CCC or anything of the sort. I've done a google search on this issue and came up empty. Hoping that someone here can offer advise.Thank you.

Seriously? Pray tell, what's here not hardware related?http://forum.avsim.net/topic/329986-hardware-related-threads/This is a third post I've tagged in past 1 day. Can't people read?Only doing this because it actually bothers me reading hardware related posts when I enter FSX forum wanting to read interesting topics about FSX and not about foreign hardware.I think mods should start closing posts again...

Don't think FSX supports SLI or Crossfire.

Since we both are using the same graphic card and drivers, all I did was set AA in CCC to 16x. That activated cross-fire for me.8x, 4x, and 2x doesn´t activate it.

Pointless having Crossfire with ATi cards just as it is with enabling SLi with NVidia cards as MSFS was never geared to make use of these graphic cards tweaks. May sound a bit too obvious, but I'm assuming that you do have 2 similar HD5970 GPUs?And as posted elsewhere, this should really be in the Hardware section.

Thanks for all your responses.I only have 1-HD5970. But the GPU Load #2 is always at zero.I switched my AA to 16x and GPU Load #2 is still at zero. I've just about given up on having GPU Load #2 working. When running another application, GPU Load #2 goes up to 100%.I called ATI tech support and they weren't much help.Any other ideas?Thanks,
