I have an ATI Radeon 6850 and have a problem with my aspect ratio. I was tweaking arma 2 to try and squeze a few more fps when I changed the resolution down, this changed the aspect ratio and this change seems to be permanent, even when I change the resolution back to 1080p. Any ideas on how to change my aspect ratio back to 16:9?
Did you tweak the .ini file? If so you have to go to steam properties>local content> verify integrity of cache to get it back to normal. If you mean in game settings some games have an option to change the aspect ratio. Did you change that?
