[The Solid lad]

I've just started renting a CS:S server and I've ran into a problem which makes me unable to play with an uncapped framerate on my server.
If I have fps_max 0 set and connect to the server, it automatically caps my fps at 59.
I've narrowed the cause of problem down to the server.cfg file, since when I start the server without it, this problem isn't present.

Could someone please take a look at the commands in that cfg file and tell me where the problem lies?
I'd give them a big thank you. :')
Attached it below.
