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
