In the Desktop effects window, under Advanced what are you using as a Composting Type? Mine is OpenGL, QT graphics System Native, Scale Method Smooth. Use OpenGL 2 Shaders is check marked. Are you using the Nvidia driver or Nouveau Driver? I use the Nvidia driver. Mine seems to hesitate when I enable the Use Vsync.
sorry guys for late , I have a lot of work anyway, under Advanced Mine is also OpenGL, QT graphics System raster,Scale Method Smooth, OpenGL 2 Shaders + Vsync these my settings
i'm using Nvidia driver - pclinuxos does not detect my nvidia card so at live or after install it now this is what it shows in PCC - Configure Video
this is what i choose
but after restat i see this the Propriety driver for your graphic card can not be found, the system is now using the free software driver (nvidia) !!
also in PCC message beside word "MODULE"
I'm confusing now which driver is loaded and in use . I've nvidia 440 GT - 2GB DDR3 BTW is this video card good to run pclinuxos KDE
