World of Warcraft + eGPU = Low Performance on Linux compared to Windows
I am posting this over as well since I believe it is more of a eGPU issue than a Wine issue.
I have a Sonnet Breakaway 350W with an AMD RX 580 and a Yoga 920 with an i7-8550u. On Windows, world of warcraft easily runs with more than 100FPS on medium settings while on Linux it struggles to hit 50 with bad frame times resulting in an unplayable experience.
I have a hunch that the eGPU might not be fully utilised or that it might be somehow related to me using the internal monitor - yes, I know there is performance loss, however on Windows the performance is more than 2x better so I doubt that it is just "using the internal monitor bad".
I am attaching my Lutris logs if it would help anyone diagnose why the heck this is running so badly.
