Hi fellas, I'm curious why is my GunZ is consistently locked at 46 fps.

Yes, I tried uncapping the in-game FPS.
Yes, my current GPU driver is up-to-date.
Yes, I have restarted my desktop (as a matter of fact, I've did that three times already.)
Yes, I have unabled Multi-sampling and another similar function which I can't remember.
Yes, I have reinstalled GunZ like twice. No changes.

This shit is weird af.
