No, it does *not* run at 60hz. There's a VERY noticable difference 
between the two. Easy way to check:
60hz (DVI) gives me tearing when running the game at maxfps 60 (because 
fps rate similar to refresh rate tends to give tearing). I only need to 
adjust it a few hz from 60 and it is smooth.
75hz (VGA only atm :(() looks good at maxfps 77, which is the only fps 
rate i can use to maintain the physics of the game (yeah, i know it's 
stupid). Plus: the On Screen Display menu of the monitor tells me what 
the refresh rate is, as I earlier posted: http://whyz.mine.nu/imgp6252.jpg

Anyway, this is not the question whether it's sufficient for me or not, 
it's a serious BUG imo. The monitor handles 75hz (According to specs, 
which also has been successfully used in Windows via DVI and in Linux 
only via VGA), but Xorg refuses to deliver 75hz via DVI!
With no changes whatsoever to xorg.conf, just switching from DVI 
output&input to VGA output&input, I get 75Hz.

So, is there ANYONE that has successfully used more than 60hz via DVI 
using xorg in this list? Am i the only one that thinks it's weird?

Kind regards,
