[Solution] CrossFire: how to make it work for FSO OpenGL on Windows
I have Win7 64-bit and 2 ATI HD 4670 and only 1 monitor attached to 1 of them: In C:\Windows\atiogl.xml add this:
Code: [Select]
<!-- FreeSpace 2 Open OGL -->
<profile exename="fs2_open_3_8_0_x64_SSE2.exe">
<CrossFireCaps>0x00000001</CrossFireCaps>
</profile>

I added it a little below
Code: [Select]
<!-- =========================== -->
<!-- Consumer Applications       -->
<!-- =========================== -->

for order reason, but I suppose you can add it anywhere.


Make sure fs2_open_3_8_0_x64_SSE2.exe and your fav. Launcher are set to run as admin. Probably this will work with the debug version and maybe with the FREDs.
Code: [Select]
<!-- FreeSpace 2 Open FASTDBG OGL -->
<profile exename="fs2_open_3_8_0_x64_SSE2.exe">
<CrossFireCaps>0x00000001</CrossFireCaps>
</profile>

Code: [Select]
<!-- FreeSpace Editor 2 Open OGL -->
<profile exename="fred2_open_3_8_0_x64_SSE2.exe">
<CrossFireCaps>0x00000001</CrossFireCaps>
</profile>

Code: [Select]
<!-- FreeSpace Editor 2 Open FASTDBG OGL -->
<profile exename="fs2_open_3_8_0_x64_SSE2.exe">
<CrossFireCaps>0x00000001</CrossFireCaps>
</profile>


I made sure the usage of both VCs wasn't Anti-Aliasing 16X, only possible with 2 VCs in CrossFire. I used GPUShark for usage % and SpeedFan for temp charting and both GPUs are in  use.

 :v:




PS: I'm glad I can give back a little to so much I have enjoyed downloading from HLP. I wrote that it could take years, but I was determined to surprise with my contribution, well is not a big one, but I think it'll save coders to have to do it and help players use their pair of VCs. I hope this is my first one of many, over many enjoyable years :)
