Fix to improve physics jitter, specially on monitors where refresh rate is different than the physics FPS.
[b]Note:[/b] This property is only read when the project starts. To change the physics FPS at runtime, set [member Engine.physics_jitter_fix] instead.

[b]Experimental[/b] If set to on, this applies buffer orphaning - [code]glBufferData[/code] is called with NULL data and the full buffer size prior to uploading new data. This can be important to avoid stalling on some hardware.
