Hey everyone! Just picked up the game and am having abit of an issue, sad to say.
I'm on World 2, and am on C.H.A.D., but am experiencing quite abit of lag, to the point where I clip through walls and the jump button doesn't register.

So, after looking around abit, I discovered the ultralow setting (note I'm already running on low). But when I apply it to my steam launch options, there is no change from low settings. (Supposed to remove animals and particles, right?)

Am I doing something wrong? I am typing -ultralowdetail into the options.

And if it is any help, I'm running on an Acer Aspire One Netbook:
1.66Ghz Intel Atom
1gb Ram
Intel® GMA 3150 Graphics Chip
OS: Windows 7 Starter

Thanks!
