Hello, Sepht. Thank you very much for contacting the Intel Communities Team. I will be more than happy to assist you.
The VSync should be handle on the Intel® HD Graphics Control panel > 3D General Settings > Custom Settings. If this is not available on the Intel® HD Graphics settings, probably the manufacturer of your computer disabled the VSync options so they can not be modified. Please get in touch with Lenovo* Support so they can let you know if this was disabled or if there is any other way to modify that.
