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

Well that's not too hard is it? Someone just needs to run it through apitrace on fglrx, and it should reveal exactly what the game is doing.

There is no difference, beside that usual midshader dissalowed.

Better if someone can made video with render comparision with fglrx and radeon, and why not even nvidia... because if this is true that R9 290 with opensource driver matches GTX 980 with nvidia driver, this should be news which does not happen every day - maybe that will be first time we smashed that green blob

But yeah it is very hard to believe without further approval

whitecat: I'm sure Valley doesn't use tessellation, but I don't know if it uses a compute shader. The log only tells us what the engine "can" use, not what the engine is using.

If that work and performance keep improving I think my idea of ditching AMD will go away. A 4 GB R9 290 may look as a nice upgrade over my 2GB 7870

Or maybe this is all about that some things behave weird on Skylake?

Yeah, I wonder what's up with that. There has to be some explanation that makes sense. Some cause that can be described. It doesn't seem like Skylake or Broadwell are stable.

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.

Maybe that motivated opensource driver developers to improve them....

I guess next time will be that there was rendering regression in mesa article

Those R9 290 results in Valley looks like in line with GTX 980... Can you Michael write article how opensource radeon driver smashed nvidia driver

Originally I was going to use the latest Catalyst 15.7 driver release, but its kernel module was running into issues on this Intel Skylake-based system used for testing on Ubuntu 15.04. Thus I resorted to using the packaged fglrx 15.20.2 / OpenGL 4.4.13374 OpenGL driver as packaged in Ubuntu Vivid that would play fine with the Skylake system running Ubuntu with the Xfce desktop.

I never enabled any drirc config when running Unigine benchmarks. Should I ? I mean, is that mandatory in order to expect having a "normal" behavior with these benchmarks ?

The benchmarks just don't work without drirc.

[gens]

so that's decided
my next card will be a radeon

IIRC the catalyst driver had some kind of limit in some cases (see catalyst vs nVidia comparisons). maybe RadeonSI will now remove it.
on another note: there will come the benefits from kernel scheduler and graphics scheduler on top??? that would be incredibly neat!
