WTF I have the same problem now with the 60fps! Suddenly it decreased from 138 to 60 and now I cant get over 60
When I set maxSmoothblabla on false it doesnt work
Turn off the dynamic net speed connection (ingame)
Turn off the v-sync in your graphic driver's settings (i think it will be the problem!)
Search the MaxSmoothedFrameRate=62 row in the UTEngine.ini (...\My Documents\%username%\...) and set it to 150 example. Set it to "false" wont occur the result u want.
If u're making movie with FRAPS than your FPS will be equal with the number of the movie's frame rate.
Almost forget, my new vga: Sapphire 4870 1GB Toxic
Improved cooling (really quiet) and raised clocks.
