Sets the Havok engine to expect around 90fps. Use this if your system can reliably maintain ~70 - 90 fps.

In case you can't make do with a pathetic 90 fps, but 120 seems like overkill.

Use this version if you can reliably maintain ~100 - 120fps

Use this if you just can't make do with a measly 120 fps (make sure that you can consistently maintain above 120 fps)

I really don't know why you'd want this, but here you go anyway.

In case your monitor is locked at 75 fps
