I tried converting to a mutable pattern, see notes #153 and even changing the renderer from Path(circle) to Circle() and it still was <15fps on iPad3.  This is all with the laser off and will need to be much faster."},"comment":{"url":"https://api.github.com/repos/phetsims/bending-light/issues/comments/131212651","html_url":"https://github.com/phetsims/bending-light/issues/167#issuecomment-131212651","issue_url":"https://api.github.com/repos/phetsims/bending-light/issues/167","id":131212651,"user":{"login":"samreid","id":679486,"avatar_url":"https://avatars.githubusercontent.com/u/679486?v=3","gravatar_id":"","url":"https://api.github.com/users/samreid","html_url":"https://github.com/samreid","followers_url":"https://api.github.com/users/samreid/followers","following_url":"https://api.github.com/users/samreid/following{/other_user}","gists_url":"https://api.github.com/users/samreid/gists{/gist_id}","starred_url":"https://api.github.com/users/samreid/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/samreid/subscriptions","organizations_url":"https://api.github.com/users/samreid/orgs","repos_url":"https://api.github.com/users/samreid/repos","events_url":"https://api.github.com/users/samreid/events{/privacy}","received_events_url":"https://api.github.com/users/samreid/received_events","type":"User","site_admin":false},"created_at":"2015-08-14T19:15:14Z","updated_at":"2015-08-14T19:15:14Z","body":"Performance still great (for iPad3) with opacity:0.5"}}
