X.Org 7.2: ATI Open v. Closed Drivers

[Michael]

Last October we had compared the performance of the open-source R300 display driver against the closed-source fglrx driver for ATI Radeon graphics cards. In that comparison a Mobility Radeon X300 was used with X.Org 7.1, but we have decided to take another look at this driver comparison under X.Org 7.2. In this last comparison, the fglrx binary blob had greatly outperformed the open-source driver. While the fglrx driver remains faster, has the performance delta between these two drivers decreased?

well it's a bit sad, but i'm really considering staying with open drivers nevertheless.

let's wait for some nouveau vs nvidia blobs comparison :]
when nouveau gets ready, that is.

First we have to look if the fglrx drivers WORK without freezing, and then we can talk about performane

What freezing/stability problems do you have?

I thought they'd be better, but I didn't know flgrx would kick ass that much :eek:
