NOTE: In the first launch it works good, but once I close it and open it again then it freezes. It is a configuration problem I think (tried to reinstall and same problem).
I tried with "cl_auth_enable 0" and "r_ext_gamma_control 0". It didn't solved my problem.
I'm using Windows 7 SP1 x86 32 bits and the latest version of UrT (just ran the updater yesterday).
P.S.: Sorry about my bad english xD.
---PROBLEM SOLVED---
Solution 1: In video settings, don't touch the refreshrate option (don't set it even on 60Hz, just let it on default). It solved the problem for me.
Solution 2: Set "r_ext_gamma_control 0"
