The game is pretty demanding, I was playing on "High" and was getting ~30 FPS. The mouse support for the game isn't so great, but then again as previously stated I was getting 30 FPS, that might be the problem there? Maybe if I tone the graphics down I'll get higher FPS and my mouse won't seem so jerky, turning my DPI up helped a bit, but then I just spin around too quickly.
I've only done the first mission thus far, but it's a pretty nice looking game, I like how most of the cursing they say in Cantonese, I found that pretty humorous. Not sure it that's possible to change, I did see something about Cantonese in the settings, but I couldn't figure out how to change it, maybe it's stuck there for the demo?
I do have a question about it though, is there a way I can stop it from disabling my second monitor? I use it for monitoring my system (temps, usages etc) and a couple other programs (TeamSpeak / Mumble etc). I did "Alt + Tab", then go back into the game a couple times, but this is a bit of an annoying 'work around', wondering if anyone else is having this issue?
