Yeah, I'm deleting my comment. I just read someone say the achievement disable thing is ♥♥♥♥♥♥♥♥. Can't confirm it right now, so I'm going to err on the side of yes, it is bs and achievements work fine.

brw, achievements are gay

i have heard conflicting reports about FOV hax and achievments. some people say it's not true, achievments are normal with FOV change. i ddint get a chance to play much tonight but ill try more tomorrow

CHANGING FOV
First you'll need to enable the console by adding +set com_allowconsole 1 to your launch options
Then, inside the game, bring down the console, and use the cvaradd command to modify the g_fov variable.
Example: (g_fov defaults to 80, we are going to modify this)
cvaradd g_fov 15 (this results in 80 + 15 = g_fov 95)
example 2:
cvaradd g_fov -15 (this results in 80 - 15 = g_fov 65)

i find 'cvaradd g_fov' 20 to give ♥♥♥♥♥♥♥♥ results. :D
