Bug ID: 91801 Summary: [amd][tahiti xt] severe performance loss Product: DRI Version: DRI git Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/Radeon Assignee: dri-devel@lists.freedesktop.org Reporter: sylvain.bertrand@gmail.com
With the same user space (mesa/libdrm...), I went from agd5f linux (drm-fixes-4.1 ee18e599251ed06bf0c8ade7c434a0de311342ca) to an official linux 4.2-rc8. All 3D games suffer from a severe performance loss.

--- Comment #1 from Sylvain BERTRAND sylvain.bertrand@gmail.com --- I tried with latest agd5f drm-next-4.3 (c2b6bd7e91aad8440a2f55bdbde6f5a8ae19fac5) The performance loss is the same than with the official 4.2-rc8.
