been thinking about what little project i'm going to do to get to grips with the new sdk for a while now, and thanks to you Suicide42, it will be a third person pink bunny masacre and you will carry a giant crowbar :)
I'd personally add the command in input.cpp on the client rather than clientcommand. feel free to post your problems with the python, sure we could help :)
oh, apologies, i just read the title :D
i'm sure you can, hunt for cvars in the console. probably a cl_, mp_ or r_
failing that, i hope you know c++ :P
i'd upgrade your cpu (and motherboard, if necessary. get a asus a7v8x-x for like £40) and graphics card. Go for a 9800 pro if you can afford it, 9600 if you can't, x800 if your loaded :)
You'll get away with 512mb ram, but you'll notice the difference with 1024.
