We will appreciate if you can also mention the model number of that.
It's in the DV6 range going by the
manual - can't work out which one exactly.
I've tried updating drivers. my computer came with catalyst control center, I tried updating that. the drivers say they are updated, but CCC says it is not compatible with my graphics adapter or something?
That "may" be due to the installer not noticing the 6770M, but rather seeing the Intel iGPU instead.
Where did you download the CCC drivers - HP's site or from AMD directly?
As Archer mentioned, it's up to HP to edit their drivers for your device.
The lag/freeze could indeed be a failure of switching from the iGPU to the discrete 6770M
when this first began I thought it was having overheating issues so I installed a higher quality thermal paste, which keeps the temps lower, but didn't make the freezing stop.
The behavior isn't indicative of heat, so you are fine there.
To determine which card is actually being used (intel or the 6770M), download
GPU-Z
Run two instances of it, one for each detected card (intel HD 3000) and (6770M). The one showing all the "load", "usage" etc is obviously the one in use.
That will help determine if the switching is working as it should.
Does the lag/freeze only occur with Chrome or all applications? AutoCAD, Games etc
