I installed it using Lutris under Arch, no issues and looks fantastic. I haven't played much yet, created my character mostly. I had to let the shaders do their thing with initial setup, so we will see if I get any stutter in the open world.
P/S, just checked Nexus Mods and there is already 900+ mods for Oblivion Remastered? I may have to spend some time modding.
