Hi, counter strike player here.
Why we have such a prehistoric way to make custom resolution ? And its not even working ? Wouldn't be more user friendly to have it like your competitor ? Just set X, Y and Hz and boom done. Been using 3rd party software to make custom resolution for example 1280x960 for almost 10 years now.
