Finally made the switch yesterday.
Had a moment of panic when the Windows install that i had turned into a VM imported but wouldn't boot and no amount of mucking around would get it to work. Fortunately, I had also kept the .vdi for the drive, so moved that onto the partition, created a VM for it, and it booted first time. Phew!
Strange issue with the Realtek network card - from a cold boot its fine, after a reboot though it always reports "No cable connected" - really bizarre. No amount of resetting the interface will resolve it, only power off then back on. I'll have to investigate that at some point.
ED launched first time just using winetricks, not even proton and gave me a smooth high quality 60FPS. Quite surprised didn't need proton. However, installed proton and will test that, but game is current undergoing an update, so will have to do it later. Might also give gloriouseggroll a go at some point, although seems like its not necessary.
Issue! - Wine detects joysticks just fine, but when i launched ED, the game couldn't see. Exited, went back to Lutris, and control panel sees the joysticks, if done from Lutris control panel settings, but when i looked at the control panel from the game settings, they weren''t visible! However, just looked again, and they are visible. Now just wait for the game to come back online and will try again.
