para los que tienen problemas con el metro 2033 pego la solución de la wiki, que al final no es en 2 sitios sino en tres xDDDD
1.- Go to Metro 2033's AppData folder at C:\Users\YOUR USER NAME\AppData\Local\4A Games\Metro 2033\user.cfg or somewhere similar.
2.- Open user.cfg and look for sick_fov and change it to a desired number with the decimal at the end, the default is 40. Note that this is not horizontal FOV like many games but instead uses vertical FOV as seen in Battlefield: Bad Company 2 and other similar titles.
3.- Save and close the file.
4.- Right-click on the file and go to Properties.
5.- Check the Read-Only box and save those settings.
6.- Repeat the process for user.cfg files found in C:\Program Files\Steam\userdata\RANDOM NUMBERS\43110\remote\user.cfg and C:\Program Files\Steam\steamapps\common\metro 2033\user.cfg
NOTE: For 64-bit installation of Windows, Metro 2033 may be installed under Program Files (x86).
P.D: yo tengo puesto 70 y de lujo!!
espero que os sirva como ami ^^
