Running Windows game on Linux using "wine" emulator.
Here's the performance numbers :
Witcher 3 on native Windows runs 40 fps at medium details and 20 fps at ultra. I don't feel any difference between 40 or 20 fps.
But, using wine on Linux that drops to 15 fps medium details, and 8 fps ultra. Gameplay is jerky even in 15 fps.
But that's for a very demanding game. Tried a second rather normal game but with good outdoor natural environment called FireWatch.
Windows native runs FireWatch at 30 to 40 fpts.
And wine on Linux provides apparently better 40 to 60 fps.
Guess need to tune the linux drivers. Need to install Vulkan drivers. Haven't installed those yet.
And then there's the question of processor heat.
Playing on Windows didn't start the fan. On Linux it start to whirl the moment I started.
I doubt it's about Nvidia. Guess processor load has something to do with it.
