Bug ID: 101198 Summary: Major performance regression for AMD card Product: Mesa Version: git Hardware: x86-64 (AMD64) OS: All Status: NEW Severity: major Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: dark.shadow4@web.de QA Contact: dri-devel@lists.freedesktop.org
With the latest git mesa, there are major performance drops. First noticed the issue with the 32bit steam game "Move or die", but it seems to affect the whole system. It basically makes the game unplayable.
