            Bug ID: 110760
           Summary: Low FPS in Quake Champions with Vega20
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: network723@rkmail.ru
        QA Contact: dri-devel@lists.freedesktop.org

I'm not sure if I should report it here or against DXVK. I've just installed
Radeon VII card on my Ryzen 7 1700 system, and FPS in Quake Champions
(Steam/Proton) is twice as lower as it was with RX480.
I've tried other applications like Unigine Superposition, Rise of Tomb Raider,
and Witcher 3 (proton), and they seem to perform as expected (much faster than
with RX480)
I've tried purging DXVK and Mesa caches, this does not seem to help. Also,
tried different DXVK versions.

HW spec:
Ryzen 1700
ASUS Prime X370 Pro
32 GiB ram
Sapphire Radeon VII

SW spec:
openSUSE 15.1
linux kernel 5.1.4
Mesa git 9fe1a925e2a4093cd88152a52ad48677d02f6ba5
llvm 9 rev 361414

--- Comment #1 from Timothy Arceri <t_arceri@yahoo.com.au> ---
Thanks for the report. Just something to note, in future you should report
issues you suspect are related to DXVK and the driver to RADV rather than
radeonsi. DXVK runs on the RADV Vulkan driver not the radeonsi OpenGL driver.

I just tried to run this on my Vega 64 with Mesa master and hit:

../src/amd/vulkan/radv_cmd_buffer.c:4839: write_event: Assertion
`cmd_buffer->cs->cdw <= cdw_max' failed.
