AMD Linux Graphics: The Latest Open-Source RadeonSI Driver Moves On To Smacking Catalyst

[dungeon]

Did you pick up a newer .drirc when you updated mesa ?

I actually never use .drirc Whatever is in /etc/drirc per version that is installed and used.

Can you reproduce those: Radeon 20%-40% faster then Catalyst in Unigine Valley? I can't.

Thanks for the benchmarks. In situations where there are rendering differences it would add a lot to the article if you included comparison screenshots.

I still remember the times when Michael didn't miss any opportunity to point out (=bash) how horrible and useless the open-source drivers are.

They should be praised/bashed on merit. Not based on whether they are open source.

Forgot to say what i see actually, yeah only what i see that Valley is slower by 10% if i uncheck Catalyst A.I.. So yes radeonsi is faster by 5% if that is disabled, but 5% slower if that is enabled Catalyst 15.7

Nothing like 20%-40% faster is there, with all default for both radeonsi is 5% slower.

Somebody played Victor Vran on R600g ? It crashes on me on a certain boss monster, looks like a buffer overflow issue. It works on Catalyst. They do ask for GL 4.1 in the requirements for Linux, but so far all the shaders say #version 150 and I have not found any call to an extension that is higher than GL 3.2. Can somebody test on radeonsi please ? :-)

Victor Vran works on radeonsi, i played it but don't hit any crashing bugs... On which level, which boss it crashed? Trace taken with apitrace might be usefull.

Ah OK you commented there, so "The crash in Royal Gardens that is caused by Argus the Dreaded Mage boss"?

Best will be if you made trace where it crashing and open a bug.

Wow if these are legit and equal. Go all that contributed to the driver. Who knows maybe when I do my new build next year I'll be able to go AMD after all AND not have the angst of trying to decide if Catalyst or the open driver is better for most of my usage or if Catalyst has been updated lately. Hope the 290 performance keeps improving in the mean time though. Why doesn't life have more send pizza and beer buttons?

I'm very curious to see how AMD cards do not support the use of open source drivers make.

I was always convinced by the freedom driver, but this is really sweet. Again, it always makes me remember the times when I started using it; that time even the radeonHD and it was more like a VESA driver. And how it has grown. Even though I am (besides a Kabini system) mainly in r600 lands (and some older) I still appreciate this development. It's okay for me that they take care of the currently on the market cards first, esp. since you can claim more of the potential HW's capabilities here and prepare them for recent SW releases (games), but I am sure r600 and such will follow, too.

I really wonder about those rendering differences. I mean tesselation on or off is easyly visable - especially with Unigine benchmarks. Would like to see some screenshots - Unigine shows the enabled settings while benchmarking too. It could be possible that some "old" drirc setting was still in place and forced OpenGL 3 mode.

They should be praised/bashed on merit. Not based on whether they are open source.

However, being open-source by itself also represents one huge merit over closed-source. But yeah, that dimension should be considered independently from other the performance properties.
