I am using Ubuntu 12.04(32-bit) and I installed the AMD Radeon drivers from the Ubuntu repos using Additional Drivers. After installing the proprietary driver I experienced a lot of screen tearing. So I enabled tear Free Desktop to reduce tearing. It has reduced the screen tearing a bit but it is still pretty bad. This does not happen with the open source drivers but the open drivers are not as fast as the proprietary ones.

The graphics card I have is Radeon HD 6410d and I have an APU, the AMD A4-3400 APU. i have also tried the newer version 12.8 of the driver. But it does not make a difference.

Thank you for any help that you can offer.
