ATI Radeon HD 3650 AGP - low core clocks?

[Skolo]

Hi. I think I have problem with my graphic adapter and fglrx (11.8). Rendering, scrolling,... etc. in some application are very slow. I`m not sure is this culprit but I found that gpu clocks are generally too low.

-idle or 2D
$ aticonfig --odgc

Default Adapter - ATI Radeon HD 3650 AGP
Core (MHz) Memory (MHz)
Current Clocks : 110 500
Current Peak : 750 600
Configurable Peak Range : [300-950] [500-650]
GPU load : 0%

-3D - (I`ve been running four instances of fgl_glxgears at once - is that relevant?)
Default Adapter - ATI Radeon HD 3650 AGP
Core (MHz) Memory (MHz)
Current Clocks : 300 500
Current Peak : 750 600
Configurable Peak Range : [300-950] [500-650]
GPU load : 49%

I`m using PCLOS 2011 KDE.

Thanks in advance!
