Bug ID: 86891 Summary: AMD/ATI Tahiti XT 7970 - long lags/stutters in games Product: Drivers Version: 2.5 Kernel Version: >=3.17 until 3.18rc1 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: bu9zilla@gmail.com Regression: No
Created attachment 155001 --> https://bugzilla.kernel.org/attachment.cgi?id=155001&action=edit 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.
