Radeon GPU does not work - some games are slow

Symptoms: mame [arcade emulator] & fceu [nes emulator] are too slow to be used. surprisingly zsnes [snes emulator] & videos on the internet work finely.

I doubt the problem is related to severe looking complaints on dmesg about the integrated Radeon GPU

Here's the dmesg output about GPU & Radeon:

I think everything worked with the previous version of Debian, but in the current version this has been the problem. I wonder if some driver has changed in the update.

Try this first:

Install driconf package and see if you can tune your video card driver options.

If problems still persist try rebuilding MesaLib to use the Gallium API and any other optional features if packages allow.

Have you installed firmware-linux package?
It shows you're missing something
[ 6.322777] platform radeon_cp.0: firmware: agent aborted loading radeon/R300_cp.bin (not found?)
