Ok, sorry for the delay, back to business. I took screenshot with Prt Scr, but it copies all black, and the screenshot's resolution is 800x600, which is weird, also i took screenshot from the game with the game hotkey, which again, the resolution is 800x600 and i can see the screenshot. But.. the game still looks in the middle, like a 800x600 square, with black in both sides, it doesn't fill the screen. I'm gonna get my camera and take a pic of the screen since i can't do it with a screenshot.
Second, yes I downloaded official drivers from the nVidia website.
About that profile to switch to 800x600, is what i'm doing atm, but, the screen should change it's resolution in an automatic way, because if i have to change resolution everytime i want to play, it's annoying, even more when i have to minimize to do something else.
And i searched in the forum before creating this thread, but i searched as "resolution problem", i'm gonna use the search tool again but this time with counter-strike.
If you need anything else, feel free to ask me, i'm more than happy to answer your question in order to get this problem fixed ^^
And again, thanks for your time.
PS: I also tried to change the monitor ratio from it's config buttons, but it didn't help.
PS 2: Some phrases might not have sense, because english is not my native language, I apologize.
