Sorry no idea, since usually i tend to avoid compiling wine, however it seems that tkg have done extraordinary job - 20 minutes seems like a very good result, but since it’s not officially released personally i wouldn’t bother try until it is released.
You can quick check 6.8r0 though, perhaps it works - Lutris should see it as i’ve explained above
Pretty good. Might even be better than the default, maybe even better than windows. This is just based on “I look at the fps counter and this is what I feel like”, though, I didn’t make any measurements. I did max out at 400 fps at one point and don’t remember this had ever happened before.
It seems to be far more stable, though. I played a couple of hours today without crashes. So if someone has the same problem, definitely try out TKG 6.8r0. (Before that, it crashed like every 3rd game)
Edit: No. It’s crashing all the time now.
