First: Thanks for your latest update, cars now look like cars again and don't just appear as bricks. Thumbs up!
Although, the battery consumption during race is enormous now. On my MacBook I lost almost 40% of battery. Another player in my league reports the same for his iPad. It seems to work on mobile though.
I'm running the latest version of Chrome on a MacBook Pro.
Further investigation in this bug is highly appreciated :-)
