Updated : I just downloaded cncnet client and installed it and while a lot has improved, the blur when scrolling still wouldn't go away. I've tested this in the first campaign of Yuri's Revenge. However, when I started up skirmish game of 1v1 there doesn't seem to be a problem with scrolling...this is the only problem I have with the game although I remotely remember it having the same problem of blurry image when scrolling through maps on certain pc when I played it back then...still have no idea what caused it.
