Bug ID: 86413 Summary: Euro Truck Simulator 2: Severe stuttering with Kernel >=3.17 Product: Mesa Version: 10.3 Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: dragon.arises@gmail.com
Created attachment 109641 --> https://bugs.freedesktop.org/attachment.cgi?id=109641&action=edit Screenshot of HUD on a bad configuration
When running Euro Truck Simulator 2 with the combination of Mesa 10.3 and Linux 3.17 or newer, the game shows severe stuttering whenever a new object enters the field of view (gets loaded to GPU RAM?) or the camera is rotated. The game stops for a short period of time, up to several seconds, just to return to a normal framerate afterwards. This stuttering is not present when combining either Mesa 10.2 with Linux 3.17, or Mesa 10.3 with Linux 3.16. With Mesa 10.4 from git the stuttering is present on recent Linux versions, but much less severe than with Mesa 10.3.

Not that I think that this contains something useful, but attached is the journalctl output that was recorded while the game was running on a bad configuration.

--- Comment #4 from Andreas Grois dragon.arises@gmail.com --- Created attachment 109645 --> https://bugs.freedesktop.org/attachment.cgi?id=109645&action=edit dmesg of the bad configuration
Again, probably not very helpful, but here's the dmesg output of a bad configuration.

--- Comment #5 from Michel Dänzer michel@daenzer.net --- Is it still bad with a kernel from Alex Deucher's drm-next-3.19 tree and Mesa Git master? If so, can you attach a HUD screenshot corresponding to that?

I've tested the latest git version of mesa combined with a drm-next-3.19 kernel, and indeed the issue seems to be fixed with this combination. There are some very minor stutters still, but those are hardly noticable and I'm not certain if they are related to the bug, or caused by something else (disk activity,...).
