Virtual Machine slow in Fullscreen mode

[indapublic]

OSX El Capitan 10.11.3 (15D21)
Parallels Version 11.1.1 (32312)
Guest: Windows 7 Professional 64-bit

Machine run fast in windowed mode but slowly in fullscreen (slow typing, slow mouse click reaction etc.)
Reinstalled Parallels Tools - no difference.
Changed video settings (memory, acceleration etc) - no difference.

I have no idea

Hi, You may go to Actions > Configure > Options > Optimization > disable Free Space: Real-time Virtual Disk Optimization.
If the "Real-time Virtual Disk Optimization" option is enabled, it may slow disk performance up to 30% (at the moment of compaction, not constantly). If the host has an SSD disk, the feature will be enabled by default for all virtual machines but will work only if it is compatible with the guest OS.

Open virtual machine configuration > switch to Options tab > Optimization tab > Set performance to Faster virtual machine; check Enable adaptive hypervisor and Tune Windows for speed. If you're not running on battery power, you can also turn on the Better performance option and check and let us know how it works.

Thanks! Trying to disable "Real-time Virtual Disk Optimization" and all works normally!
Then I enable option for test - and virtual machine works fast whatever.
Very strange. But thank you very much for your help!
