Thanks for the feedback. Shame to hear you are having trouble on macOS, performance optimisation is definately something I will need to look into. I will see what I can do about the freezing when leaving a race. The good news is in the next v0.4 update, I am implementing an options screen where you can adjust the quality settings, which will hopefully help.
That sound great! One more thing, I don't know if you have thought about this already, but having there be some way to standardise car models in a tournament would be great. Having them all be different models can break the fun and there are some models that i just don't wanna race with that much. I know it can be changed in the custom tourney, but having that in the future tournament mode is a must for me.
