Mark,

We are aware of performance issues on some configurations (especially with Firefox). We’ll work on these while adapting raceQs for mobile devices.

Meanwhile:

1. Make sure your video card driver is up-to-date

2. Use Chrome

3. Use minimum features:

– un-check some boats on “Fleet” tab

– select some tab other than “Setup” (which visualize more marks)

– choose shorter “Trail”

Hope this helps
