I updated from a 2.2(?) dev build and noticed a lot of screen tearing.  I enabled vsync and noticed there wasn't any input lag (which is the reason I don't use it).  vid_fps 1 shows that I'm capped at 72 fps whether or not I have vsync on or off (which is what my monitor runs at).  I still have a 1.9 version I use for testing and on that I can easily hit 1000 fps.  This is a big deal to me, the screen tearing is terrible.
I should add that I have vid_refreshrate=72 set in the ini.  I have to do this in order to load the game without my monitor rebooting so-to-speak. 
I just tested the official versions, 2.1 and 2.2.  2.1 works fine, 2.2 has the vsync issue.
Okay, I deleted my ini file  and sorta fixed it.  Now with vsync off it's capped at 200, which I'm assuming is intentional.  I guess there was something out of date about my previous ini settings.

200 is the default value of vid_maxfps CVAR. Set it to zero to disable the limit.
