when i upload the toribash screen all the letters and numbers looks like this
"JJJJJJJJJ"
"1111111"
"QQQQQQ"
"AAAAAAA"

and so on, so when i'm playing toribash, idk what people are saying and i can't read their names.

Hi,

To fix the issue, update your graphics card drivers.

Read here on how to do so.

Hi 'im just wondering... doesn't that cost?

No, updating drivers are free, and can be done through device manager, or your manufacturer's website.
