Valheim on Proton works better with OpenGL (34-50fps) than Proton with Vaheim’s Vulkan (15-20fps) mode. Native Linux builds are only getting 15-20fps. It’s kind of weird considering the lead developer does his work on Linux. I know the game has yet to be optimized, but I fear that Unity is just going to suck on Linux. My specs: Xubuntu 20.04, i5-9600K, 16gb RAM, rx580 8gb, radv and Mesa from oibaf ppa. Anyone experiencing similar performance in this game?
