Screensavers ...  are these a library of images or are they X or GL
dynamic computational
heavy screensavers.   Which graphics cards are installed and what
driver is active.
Is acceleration using the card enabled or is the load on your CPU.
Texture maps?

Double check driver install and setup for GFX cards.

Is OpenGL installed? Correctly?
Chrome/Chromium and FIrefox allow hardware acceleration on graphics cards.
Toggle on and off to test.
