Why is the engine frame-rate limited?

[Spiegelman]

Speaking of v-sync, I don't think vsync works at all in this game.

Turned it on, tearing in the sewers all over the place.
Tried forcing vsync and triple buffering via d3doverrider, still tearing.

Am I doing something wrong?

I had tearing before I turned it on, but haven't experienced since then (in the Prison now). Maybe try changing your monitor refresh rate to 60 if it isn't already? Or maybe Eigen will come back and can help.

My refresh rate of my monitor is 60 though...

I'm not sure then... If I experience the same problem in the sewers with v-sync enabled I'll post in here or my compiled bugs list.
