Can't activate view optimization

[Kirk]

Hi,

I can not activate in the Addon Manager "view optimization". When I set the hook and press to save the change after a reboot away. The start of FSX with administrator rights has not helped.

Any ideas?

Thank you..

That option is not saved. Is not required, it was made just as an experimental feature, but we found it's not doing much, it could help with fps on low end systems, because it turns off objects behind you, but it will increase stuttering so, we left it to be settable to do tests, but we don't keep the settings.
