suddenly fps drop after upgrade

My fps suddenly drop after upgrade from ver 2.0 to 2.1 and Leopard 10.5.2 to 10.5.4. I try to run island demo 3d platformer in the editor and standalone build. The fps is too low about 3 fps.

Same result when display island demo from unity website. Is it the problem with my upgrade 10.5.2 to 10.5.4

Have done some testing. It’s just fine with 10.5.2 but not on 10.5.4.

If you have a reproduction case then by all means get a bug logged. Even if the repro case is one of our demos, log the bug from the machine experiencing the performance drop. I don’t know of any clear issues that would be causing this but at least with a bug being logged our dev team might be able to sort out the issue. Thanks.

Sorry, it seems my system problems. Solved it by reinstall the system.
