So recently I've been having a problem on some maps from time to time throughout the day where for a second or two on certain portions of maps it will feel like my sensitivity will shoot up, either that or my frames skip or something but it certainly doesn't feel natural and usually I can not surf through those parts. I don't have a very good cpu but I get about 200-300 fps ingame most of the time. I close fraps and chrome and everything else in the background besides css and steam, this seems to help but still doesn't fix the problem. It has been very annoying lately and I'm not sure what I should do :( If anyone else is having this problem I would also like to know that I'm not the only one!
