Bug ID: 54693
           Summary: Freedom Planet 2 performance is atrocious with
                    near-zero hardware load

          Priority: P2
         Component: -unknown

wine64 FP2.exe log

When running Freedom Planet 2 v1.2.0 on LGA-2011/Xeon E5-2697/AMD RX580 under
rolling-release openSUSE Tumbleweed it gets atrocious ~10 fps in levels and ~45
fps in menus with ~1% GPU load, despite being simple low-res 2D game. The
executable is 32-bit d3d11 Unity-based app.

I actually use wine-staging but I can't test vanilla now to see if its
different. However, one interesting part is that enabling WINEESYNC tanks fps
more than twice of even that: <5 from 10. With WINEESYNC=0 CPU load is mostly
on single core to about 60-80% but with WINEESYNC=1 load is shared among all 24
CPU threads to be almost unnoticeable, yet performance is literal slide-show.
Tested with wine's GL rendering and dxvk with same result, wine's vulkan
renderer hangs at startup.

In comparison, Dishonored 2, pretty visually taxing game, maxed out with same
wine/dxvk settings gives buttery-smooth native 72 fps (OC 60 fps panel) with
<80% GPU load.

There is nothing obvious in what little logs it spews out and there seem to be
no audio or visual glitches. I'm quite at a loss to figure out what might be
the bottleneck.

--- Comment #1 from Predatory QQmber  ---
Demo build seems to be also affected. As such, it can be used for testing.
I doubt that it's rendering-related since even forcibly running it with CPU
rendering only barely increased CPU load while fps and look stayed the same.

For fps counting I use either
`GALLIUM_HUD_PERIOD=0.07
GALLIUM_HUD="cpu+GPU-load+gallium-thread-busy,.dfps+.dframetime,.dbuffer-wait-time;requested-VRAM+VRAM-vis-usage+mapped-VRAM+requested-GTT+GTT-usage+GFX-IB-size,GPU-shaders-busy+GPU-ta-busy+GPU-vgt-busy+GPU-sx-busy+GPU-wd-busy+GPU-sc-busy+GPU-pa-busy+GPU-db-busy+GPU-cp-busy+GPU-cb-busy;.dprimitives-generated+.dclipper-primitives-generated+.ddraw-calls,.dsamples-passed+.dps-invocations"
VK_INSTANCE_LAYERS="VK_LAYER_KHRONOS_validation,VK_LAYER_MESA_overlay"` for
Mesa or
`DXVK_HUD=devinfo,fps,frametimes,submissions,drawcalls,pipelines,memory,gpuload,api`
for dxvk.
The FP2.exe should be started with '-popupwindow' option or aspect ratio will
be screwy.
