|Hi again :)|
Ok third time (after THIS and THIS), now I have gathered a lot of info and found all the symptoms.
My laptop, HP Pavilion G6-2355SO, is sporting AMDs Dual Graphics.
With Dual Graphics the APU and the GPU works together to maximize performance. This works in theory, but not so much in reality. Disabling the Dual Graphics leaves me with the APU, and it does a good job, but I think I could get more out of my PC if I got to work with the GPU alone.
Having Dual Graphics on causes microstuttering, even though FPS counters show "high" FPS it feels like its much, much lower.
If I open CCC and click on "Switchable Graphics Settings", I can choose what graphics processor to use. "Power Saving" option uses the APU and "High Performance" uses APU+GPU, which causes massiv microstuttering. If I enable VSYNC it helps with the microstuttering only a little bit, but not enough. And using the "Power Saving" option leaves me with lag.
There is no option in the BIOS to disable or switch the main graphics processor.
I'm currently using Catalyst Driver 13.3 beta and have updated the BIOS.
CCC shows the APU as primary adapter, and the GPU as "linked adapter".
The APU, 7640g, has 512mb available ram, from which it shares from the same pool as my CPU. I have 6gb of DDR3 ram, 1600mhz.
The GPU, 7670m, has 1024mb of dedicated ram, DDR3 1800mhz.
My AMD 4 cored CPU runs at 1,9ghz with a boost up to 2,8ghz if needed.
I need a way to use the GPU. The GPU should work fine on its own, so I'd like to utilize it.
Thanks in advance.
