Ah yes it is rather poorly optimized. Before it I was playing Against the Storm which doesn’t have such high requirements.
Also Mount and Blade provides some amazing single player experiences that are hard to find elsewhere. Get into a battle with hundreds of units, command a cavalry charge in first person while you personally lead a flank from the other side.
Which is actually my preference. How do you get per application keyboard settings for Linux? Seems like it’s not usually built in.
