If u are experiencing bad FPS and lag, chances are that your video card is not quite up to snuff. I'd recommend u drop ur rate to 20000 + see how that works as it's the default of most servers.. If u don't have better than the latest + greatest SLI/Crossfire or close then you need to drop your rate to 20000 or even 15000.

Fluffy, since most of the people here decided to criticize your computer and internet connection, I'll give a run-down of everything.
First off, it's the server for choke; I know this because of everything I have set, and my computer specifications.
Rates/FPS rundown:
cl_cmdrate 100
cl_updaterate 101
rate 30000
fps_max 101.
The largest smooth-game you can really get at the moment are 20 man servers at 100 Tic-Rate that are FPS-Boosted to 2000 server side fps (which is the max server fps available). Anything higher than that just demands too much on today’s hardware/bandwidth limitations and you will get choke.
I don't know what the server may be at, but there is a lot of obligation on the server; so I really don't think it's holding up. I have everything set perfectly, FPS stays at 101, internet connection has no issues, and no contentions with how my computer is in-taking information.
Either way, if everything you have is set to what I stated above, there should be no problems; although I still have choke -- which infers that it's server side.
