Xorg.log
I just installed ubuntu 15.10 (with oibaf and commendsarnex ppa to see how good
is my radeon hd4770 (rv740) works with fresh graphics stack).
Unigine Valley-1.0 (native) and MafiaII Game (wine with Gallium Nine) was used
to see video performance differences against windows7.
Linux Unigine Valley Benchmark 1.0:
FPS: 8.5
Score: 356
Min FPS:4.2
Max FPS:13.8
Windows7 Unigine Valley Benchmark 1.0 (dx11 render, as opengl wasn`t able to
run):
FPS: 15.9
Score: 666
Min FPS:9.2
Max FPS:29.5
Linux Mafia2 Game (internal benchmark) under wine with Gallium Nine, dri3):
22.2fps
Windows7 Mafia2 Game(internal benchmark) under wine with Gallium Nine, dri3):
42.4fps
It works (without visible artifacts) and it is great!, but it is almost twice
as slow against windows. There are some benchmarks on phoronix
(http://www.phoronix.com/scan.php?page=article&item=radeon_1404_win81&num=3)
for more recent and powerfull r600g hw, and there was no such big differences
there.
So is it r700 classs hw works slow with gallium in general, or it something
wrong with just rv740 support? (or something else ...?)
