You need to (i) read the Catalyst Mobility webpages on the AMD website and (ii) read the Catalyst Mobility driver release notes .. and (iii) talk to ACER about any driver issues, it's their machine, they support it, not AMD !
The latest BIOS version for the GPU is whatever ACER have installed, again, you'd need to talk to them about things like that.
