Yeah it runs l4d2 at around 40-80 fps depending (far cry from the 300 catalyst spits out but smoother non the less, no stuttering more responsive ) at max settings full HD. It just handles DOTA2 like crap for some reason.

By the way is HyperZ disabled in mesa 10.1 for radeonSI or just r600?

BTW 10.1 is out http://lists.freedesktop.org/archive...ch/000077.html

This testing does continue show for those who have long told companies "just release docs or code to the community!" and then believe a driver will magically happen that's made by the open-source community and on-par with the binary blobs, it's not that easy, even for a six year old graphics processor.
FGLRX:
200% Speed
0% Freedom
80-90% Stability
Radeon:
100% Speed
100% Freedom
99.99 Stability
- Wayland can be used
I think Radeon is not on-par but on-top of the Blob.
And another thing, its not that AMD released on Day X the complete Docs for the gpus, I am not even shure if everything that docs exist on is released. Or what people need. Especialy on the newer cards.
When I think on the vdpau stuff, that could have been done much faster if the docs needed for it would be released several years earlier.

Originally posted by Vulkan View PostI was hoping SteamOS would prompt AMD into releasing the 13.9 legacy driver for Linux.
Nice to see how much the open source drivers have progressed however.
I've installed a LXDE based Fedora 18 for gaming, with Catalyst legacy 13.1 (downgraded xorg, to 1.12). I'd really like to re-build it but... I just don't feel like it anymore. Downgrading xorg is a PITA for a noob. I'll just restore the backup image and let the grub and os-prober bring it to life for me.
Anyway, on HD3650 Catalyst legacy 13.1 eats OSS Radeon for breakfast. Only thanks to Catalyst I was able to enjoy >smooth< gameplay of Portal, Amnesia TDD and TF2. With OSS it would all be an ordeal. So to summarize the article: Newsflash. Elvis is still dead.

Given that the drivers were left running with default settings and no alterations, I'm left with a few questions, but mostly: at this point, is there a timeframe for enabling geometry shaders and HyperZ for R600/R700 hardware by default? I expect the lack of HyperZ is holding things back by 20-30% on average. Figuring out how to work around whatever glitches or quirks are present in the hardware so that can be enabled would close a LOT of the speed gap between the fglrx and Gallium drivers by itself.
