I'm aware that esync exists, what is your point?
Nothing special, i noticed that a major performance hit isn't coming from DXVK it self. It is a good idea to always test DXVK with ESYNC on Linux in order to have a real measure VS Windows. Otherwise you will end up continuously searching for optimizations to match the native performance.
I'm not sure you understand how it works. You don't have to worry about Doitsujin.
Nothing extracted yet.
Its a good idea to consider Wine esync to DXVK performance goals. Keep up the good work.
