In firefox everything goes smooth - in your demo on http://trackingjs.com/examples/face_camera.html it gives me around 30 FPS while in chrome performance drops to 11 FPS. I got pretty strong setup of hardware so that should not be the problem. CPU load is similar in firefox and chrome (around 20%). I also tried it on weaker machines and the performance drop was much stronger.\r\nMy Hardware:\r\ni7-4710HQ 2.50GHz\r\n8GB RAM"},"comment":{"url":"https://api.github.com/repos/eduardolundgren/tracking.js/issues/comments/162720456","html_url":"https://github.com/eduardolundgren/tracking.js/issues/118#issuecomment-162720456","issue_url":"https://api.github.com/repos/eduardolundgren/tracking.js/issues/118","id":162720456,"user":{"login":"jhn","id":678798,"avatar_url":"https://avatars.githubusercontent.com/u/678798?v=3","gravatar_id":"","url":"https://api.github.com/users/jhn","html_url":"https://github.com/jhn","followers_url":"https://api.github.com/users/jhn/followers","following_url":"https://api.github.com/users/jhn/following{/other_user}","gists_url":"https://api.github.com/users/jhn/gists{/gist_id}","starred_url":"https://api.github.com/users/jhn/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/jhn/subscriptions","organizations_url":"https://api.github.com/users/jhn/orgs","repos_url":"https://api.github.com/users/jhn/repos","events_url":"https://api.github.com/users/jhn/events{/privacy}","received_events_url":"https://api.github.com/users/jhn/received_events","type":"User","site_admin":false},"created_at":"2015-12-08T01:03:53Z","updated_at":"2015-12-08T01:03:53Z","body":"Same here.
