I'm using a Toshiba Satellite T135D with GPU Radeon Mobility HD 3200
I've installed latest driver catalyst from AMD and why the graphics performance of my laptop become slower than previous? My step
Download and install the driver
sudo aticonfig --inital -f
Turn off Vscync and change the refresh rate in CCSM, but the performance still laggy T_T
With your GPU, best would be to switch to Unity 2d.
