Excellent feedback, thank you very much! I have that exact Mac mini in the office so I will try and repro today. Sounds like the game is GPU bound for some reason. Any chance I could get Chrome version too? The executable shouldn’t have this issue, it’s just the WebGPU graphics api in Unity is a bit experimental still.
Totally agree with the UI as well. I was trying to go for something minimalist, but feels a bit placeholdery for sure.
