also lol at most toxic guy around calling others out on this sh**
im just waiting for meganerdbomb to come along and kick things into gear.
i attached a screenshot. I did add the I fix there and still get this. I already set compatibility to windows 7 trying to see if maybe that would help the screen. that screenshot is full screen, but it does the same for windowed as well, just has a title bar. I even tried it in 640x480 windowed and it's still zoomed in like that. no idea why. i mihgt not be able to play the base game. The DSL version does work for me at least.
Maybe try downloading a fresh copy of stock from here? If all else fails you could rename your stock game's UI folder and copy over the UI folder from your DSL install. It's certainly not an issue with RA2 itself (as DSL is working) so it must be an issue with a config or UI file.
