Right, so, I got this laptop about a week ago and have been intending to use it for basic computing and some light gaming. I didn't expect incredibly much out of the card but I was surprised when the APU was outperforming the dedicated card. In Borderlands 2 I was getting ~20 fps on the APU and about 9 fps on the GPU. Using MSI Afterburner and Asus GPU Tweak I found that the dedicated card was clocking itself to about 300 or 400mhz instead of the 775 the technical specs have it rated for. (Specs found here: http://products.amd.com/en-gb/MobilityGPUDetail.aspx?id=150&f1=&f2=&f3=&f4=&f5=&f6=&f7=&f8=&f9=&f10=&f11=&f12=&f13=&f14=&f15=&f16=&f17=&f18=&f19=&
As you'd imagine this is rather frustrating.
I've updated the drivers, I've double-checked that the applications involved are set to use the "high perfroamnce graphics" as stated in Catalyst. I've disabled/enabled the dual-graphics mode in Catalyst. I've made sure the laptop's power plan is set to high performance. I'm stumped, frankly.
