Well even for me it feels slo-mo, but if you unban me i can even prove that i use no hacks at all [Ill make a video of opening the game..etc and how slow it feels like]
I am not hacking, never was, never will.
Edit: My cl_showfps could be broken, since it never never ever goes over 600, that's why i said 600 but it could be alot higher, so really i have no idea what the fps is if it says constant 600.
