Sometimes (frequently enough) the game starts to work extremely slowly. These periods of low performance usually begin when I'm going to a new location, but it can also begin after pause menu, viewing inventory or some other actions. Usually, these periods of low performance end itself after some time, but in other cases it lasts very long time. I've tried to enable/disable single threaded mode and steamworks setting, but it doesn't help.\r\n\r\nv1.11 doesn't have such problem on my machine.\r\n\r\nI've recorded demo videos using my smartphone, so the performance isn't affected by recording software and you can easily see the difference between different versions.\r\nv1.12: https://youtu.be/ugWmL_LzGMM?t=43s\r\nv1.11: https://youtu.be/IlHDXjgUrSs?t=2m2s\r\n\r\nMy hardware:\r\n— Intel Core i5 4460\r\n— Intel HD Graphics 4600 (driver v10.18.14.4414, 2016-03-23)\r\n— 16GB RAM\r\n— SSD Crucial MX100 512GB\r\n— Windows 7 x64"},"comment":{"url":"https://api.github.com/repos/renaudbedard/fez-1.12-issues/issues/comments/234007316","html_url":"https://github.com/renaudbedard/fez-1.12-issues/issues/113#issuecomment-234007316","issue_url":"https://api.github.com/repos/renaudbedard/fez-1.12-issues/issues/113","id":234007316,"user":{"login":"vrubleg","id":2157439,"avatar_url":"https://avatars.githubusercontent.com/u/2157439?v=3","gravatar_id":"","url":"https://api.github.com/users/vrubleg","html_url":"https://github.com/vrubleg","followers_url":"https://api.github.com/users/vrubleg/followers","following_url":"https://api.github.com/users/vrubleg/following{/other_user}","gists_url":"https://api.github.com/users/vrubleg/gists{/gist_id}","starred_url":"https://api.github.com/users/vrubleg/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/vrubleg/subscriptions","organizations_url":"https://api.github.com/users/vrubleg/orgs","repos_url":"https://api.github.com/users/vrubleg/repos","events_url":"https://api.github.com/users/vrubleg/events{/privacy}","received_events_url":"https://api.github.com/users/vrubleg/received_events","type":"User","site_admin":false},"created_at":"2016-07-20T16:41:59Z","updated_at":"2016-07-20T16:41:59Z","body":"OMG.\r\n\r\nI've installed driver v10.18.10.3907 (2014-08-05).
