I have an older desktop system with an integrated AMD HD 3200 (RS780), 4 GB Ram and AMD X2 3800, HP LCD with 1600 x 1200 resolution.
I reinstalled Linux Mint and actually - finally ! - managed to install the proprietary fglrx ATI driver, if I check it, it is properly installed (fglxinfo), glxgears and the cube animation work fine and fast. So - 3D graphics, which I don't really need on Linux, seems to work. Having said that, what keeps annoying me is the 2D performance. It does not actually feel slow. For example, scrolling up and down on a page like dpreview.com is fine, if not as buttery smooth as on Windows 8 using the same system.
However, if I drag a window (medium size), especially fast, there is incredible tearing! I did enter the Catalyst Control Center via sudo amdcccle and activated the tearfree mode. Yet, it does not change anything.
Do you have any idea what the reason could be and what settings I could change? In CCC there do not seem to be any other relevant options for 2D performance. Everything seems to be OK concerning the settings.
Could this be related to the Xorg.conf? If so, what settings could I try?
I really made up my mind to use Linux Mint and not Windows 8 as my main system (word processing, Internet), but it is kind of frustrating that Windows 8, which has officially much higher hardware requirements, seems to be as fast graphics wise like Windows XP before, whereas I have never been able to match Windows 2D video performance with Linux on that system.
I simply want to have smooth, fluid 2D performance (scrolling in browser, moving windows, etc.).
Thanks in advance for any help.
