ATI Open vs. Closed AIGLX Performance

[Michael]

what does 2d xf86-video-ati driver have to do with that? basically nothing.

various mesa branches and versions should have been tested instead.

Oops, yeah, didn't mean to have that in there. Was multi-tasking too much yesterday

Phoronix: ATI Open vs. Closed AIGLX Performance

For those that may have missed it, the ATI/AMD fglrx 8.42 display driver that was released last month had introduced AIGLX support. The open-source "Radeon" driver for ATI graphics cards going up to the R400 generation has supported AIGLX for quite some time, but the ATI binary display driver hadn't until last month. However, one of the complaints about the fglrx implementation of AIGLX is that in the 8.42.3 driver, some are encountering slow performance in Compiz / Compiz Fusion. We have taken an ATI Radeon X800XL 256MB PCI-E graphics card, which is supported by both the Radeon and fglrx drivers, and have compared their Compiz performance in a few different scenarios.
