Kernel config of 3.18rc1
Since kernel Version 3.17 and greater (last tested with kernel-3.18rc1) i'm
encounter very long stutters/lags (1-2sec) when i'm gaming various games. (eg
borderlands2)
Usually i'm doing a unigine valley benchmark test after i install a new kernel
to see how much more performance i get and usually the benchmarks are very
promising. (FPS continuous rises) :)
However since kernel-3.17 i get really long stutters/lags in my tests. FPS
doesn't really go done, they rise even more (max fps), but i also always get
really serious stutters, where i have to wait about 1-2 sec until the graphic's
continue to render. This is really annoying.
Besides getting higher max fps in Unigine i also get new lowest min fps.
Below a short overview of my benchmark tests (with date):
Linux 3.16.2-gentoo x86_64 - 20140914
FPS: 17.4
Score: 727
Min FPS: 8.2
Max FPS: 28.1
Linux 3.17.0-rc6 x86_64 - 20140927
FPS: 16.2
Score: 680
Min FPS: 4.2
Max FPS: 32.1
Linux 3.18.0-rc1 x86_64 - 20141025
FPS: 15.9
Score: 666
Min FPS: 3.2
Max FPS: 34.4
Today's test (same software stack, just different kernels)
Linux 3.18.0-rc1 x86_64 Linux 3.16.3-gentoo x86_64
FPS: 15.9 18.7
Score: 666 782
Min FPS: 3.2 8.3
Max FPS: 34.4 30.5
Usually downgrading to kernel-3.16 always solves the problem for me which is
why i think the problem has todo with the kernel side of the ati driver.
I've also tried the new firmware blobs for my graphics card (TAHITI_ce.bin ->
tahiti_ce.bin, ...), they didn't make any differences.
