If you’re using Nvidia then try getting the latest driver, i.e. 396.54.02 (Vulkan beta driver). It solved the last graphical glitches for me.
The launcher crashes most likely because DXVK will produce a lot of log messages and this messes up the launcher somehow. You need to set the environment variable DXVK_LOG_LEVEL=none
and this should stop it. I’m using the standard Windows launcher and it may be different for the Linux launcher.
Anti-aliasing is off by default and will always be off on start, unlike Windows. I’m guessing this was done intentionally by CCP. I don’t know why it would do this otherwise as it’s working just fine with AA.
The low CPU usage is indeed the best part of it all. I can leave my clients running all day and only minimize them. They barely use any CPU unless I bring their windows up. It’s like always having something to play with while sitting at the computer, only it’s not Windows + Solitaire, but Linux + EVE.
