Stop using Lutris and start using Bottles.

Is vulkan something supported in the game? or its something the bottles can translate?
I've been trying bottles to play some old games ~ 2000 era.
And can only use open GL as display option.
And even with gamescope I'm getting like 30-40 fps.
So am I doing something wrong? or it's limitation of the game engine?
>TL;DR
How to use vulkan with bottles?
