Hello
I've got a intel440bx with a Radeon7500 rv200 chip , running x4.3, on kernel 2.6. System is built from source entirely.
One strange thing I noticed is that when I run glxgears in a small window say 2x2 inch, cpu utilization jumps above 70%.
But when I maximise the window, cpu utilization drops to 1-2%. I can see this clearly in gkrellm.
I thought it should be the reverse.
what gives??
When the card has to draw less pixels, a larger percentage of the time is spent sending commands from the CPU to the card. When the window is tiny, the card is drawing fewer pixels, but the CPU has to send the same number of commands per frame.
