I noticed this to, but im using it on my macbook so its also not optimal for me.
For those who want macOS support you'll need Crossover to run the exe. It runs perfectly fine and hasn o lag what so ever.
Sadly they probably wont update it for cross platform. But on the bright side I've gotten it to work perfectly on Crossover. So if you want to use it that way it works perfectly fine and runs great.
