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 found. 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 making big changed in the engine and supporting the opengl4 only for linux was a waste of time when they are also adding vulkan support (not yet enabled by default, but one can enable it changing the config file). This vulkan support is still 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 it anymore. Also, probably next version (probably around the end of year) will release the vulkan support for all OS.
