Generally, the intention is for the defaults to be safest, and changing them incurs a certain risk. > * a recommendation I found somewhere (is this necessary?) > >> Option "GARTSize" "64" # default is 8 Mb The default may be too small for demanding 3D applications with the r300 Mesa driver. > * improve power consumption (I'm on a laptop, does this cause problems) It can cause problems on some hardware setups. > >> Option "DynamicClocks" "on" # default is off > >> (on=faster?) The purpose is to save power by automatically disabling the clocks of idle GPU blocks. This can't increase performance but may decrease it slightly in some situations. > * I use radeonfb and the man page says I can turn this off (problems?) > >> Option "VGAAccess" "off" # default is on (not > >> required for radeonfb) I wouldn't use this on your machine, it's mainly for powerpc machines where legacy VGA access just doesn't work. > > You should try EXA instead of XAA too (especially with Xserver 1.4). > > I've been trying this on and off, but with my compiz desktop, EXA is > terribly slow to draw the windows. As of X.org 7.3, compiz should be faster with EXA than with XAA with the r300 Mesa driver. -- Earthling Michel Dänzer | http://tungstengraphics.com Libre software enthusiast | Debian, X and DRI developer
