Lately I've noticed a grainy appearance to the game. It's not that big of a deal, but I'd like to know what's going on. Here's two screenshots where I've been able to notice the strange visuals. What's really bothering me is the game kept freezing up during gameplay the last few times I've played it. The maps I've used recently was WCA and Fujigoko. Some of the freeze ups were short, while others were a bit longer. The freezing is something I've never noticed in the past.
