I have two Asus R9 280X in my computer. They are not running Crossfire. Is there any way to configure Fraps, Dxtory, OBS or any kind of capturing program to use the secondary GPU only for capturing the gameplay?

I have tried using OBS with AMD VCE but I think it uses the primary GPU for the capture and encoding, which gives me a performance loss.

No. Capture software works by copying whats in the video frame buffer so copying the buffer of car thats not running the game would get you a video of the desktop.

You can try AMD Gaming Evlolved capture software which would use the GPU's hardware video encoder to convert the files to h.264 with little impact on the cpu.

Thanks. I tried AMD Raptr with Crossfire and it's working surprisingly well. I barely get any performance loss at all when recording. Although the second GPU is under 0% load according to MSI Afterburner, but the secondary GPU has to be doing something because I get tons of more lag if I disable Crossfire.
