Bad 2D-acceleration for proprietary ATI-driver?

matrem · 12-29-2003, 04:18 AM

I have finally succeeded in getting my ATI 9500 card working with the proprietary fglrx driver they provide. This gives me 3D acceleration. But now whenever I move or resize windows, or switch desktops, this takes a lot of CPU, as can be checked with top. This is very noticeable and so annoying, that I set DRI off again with Option "no_dri" "yes" in my XF86Config-4. This solves the 2D-issue, but now I have no 3D-accelaration again!! Does anyone else have this problem?

I don't have this problem with my Radeon 9000 Pro and their fglrx drivers.
I get rather good performance, both 2d and 3d.

When you say a lot of cpu, how much do you mean?

Well, it is up to 70% for my XFree86, just dragging windows around. Of course, I have to shake them like mad to reach that, for normal use it is simply noticeable, like 20%.

it's probably because you have an old cpu

I have an Athlon 2500+. The problem is gone if I turn DRI off.
