I'm using the Asrock Extreme4 mobo, and the gtx 670. I also have HD 4000 graphics b/c of the 3570k CPU. I just installed Arkham City, and I'm getting a score of 20 (fps I assume) on the benchmarks tests in game. I've concluded I'm mistakenly using the onboard graphics instead of the 670. Does anyone know how to disable the HD 4000 in this specific bios, on this mobo?
in the bios there be a setting to change the first video device. by default it the intel ipeg. change it to pci. in that same menu under it will be a setting to turn off the intel gpu. by default is set to auto.
