Bug ID: 110211 Summary: AMDGPU Fury X Unplayable Slow Down on Dota 2 Product: Drivers Version: 2.5 Kernel Version: 4.4-rc4 Hardware: x86-64 OS: Linux Tree: Mainline Status: NEW Severity: normal Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: wittyman37@yahoo.com Regression: No
OK, so I tested the 4.4-rc4 kernel and all was well from what I could see with dmseg and steam. However, Dota 2 is REALLY slow while it worked well with the 4.3 kernel. Left 4 Dead 2 and regular usage seems fine.
I am trying to bisect now but am running into compile issues while bisecting with Arch Linux. Here is my post that forum. https://bbs.archlinux.org/viewtopic.php?id=206660
I tested rc5, rc6, and now rc7 with no improvement. The 4.3.3 kernel that was updated in Arch Linux today works well.
