Radeon Open source drivers are running just fine here in TF2... most of the steam/humble bundle games i tried are running just fine... so fine that i don't install the fglrx driver any more.
So probably the problems you are finding its just related to that APU or some setting you enable.

Since the APU IS the GPU, that is of very little comfort.
Also, the Radeon open driver is nowhere near the performance of the fglrx on a dGPU like the 7750 ( dunno about the APU, doesn't work ).
TF2 works fine with most special effects disabled, but, then again, I would have bought an Intel with HD4xxx for that.
AMD markets their APU as best value CPU+GPU, basically stomping over Intel's iGPU. This may be the reality in Windows, but in Linux, only old or simple engines, 2D titles and the like work OK-ish.
