Comme= nt # 11 on bug 10197= 8 from higuita@gmx.net
As we can't control the installed game version (auto-update to=
 startup), we
can't now test the older opengl4 version anymore, where this problem was fo=
und.
Before the upgrade that removed the opengl4, i got higher fps with
power_dpm_force_performance_level setting set to high. That was with kernel
4.16 or 4.17

Warthunder dropped the opengl4 engine (only used in linux) and reverted to =
the
opengl3 (also used in MacOS) for linux. They did this because they were mak=
ing
big changed in the engine and supporting the opengl4 only for linux was a w=
aste
of time when they are also adding vulkan support (not yet enabled by defaul=
t,
but one can enable it changing the config file). This vulkan support is sti=
ll
not complete (some drivers have rendering bugs, i can see some micro-freezes
sometimes), but the future looks promising.

With opengl3 in the 4.18.9 kernel, at least for me (rx480 and latest mesa),
performance increased about 20% over opengl4 (but again, comparing different
engine versions)
With Vulkan, i get always 60fps (vsync is enabled) and the GPU is using the=
 top
sclk speed, so at least vulkan is working fine.


So i vote to close this "obsolete" or similar, as we can't test i=
t anymore.
Also, probably next version (probably around the end of year) will release =
the
vulkan support for all OS.
