So today i was messing around with game resolutions and discovered that the images start looking really wierd when the game isnt in 800x600. I also decided to go and check out if the game suported images of different resolutions, it doesnt. So my suggestion is that the game would do something like detect the image resolution and strech it out to equal the game resolution accordingly instead of adjusting it as if it was an 800x600 image anyway (causes for the scope to be in the wrong area and look just as pixelated).
Nothing we would die without in the game, it would just add a better use to the resolution option in the config, and make modding a bit more fun for some of us.
