Disclaimer: I'm about an hour and a half into the game.
The default settings of the game make the *menus* run at an absurdly low frame rate on my mid-range PC. It's incredibly frustrating to navigate to the graphics settings to turn down the anti-aliasing. Once that one setting is turned down, the frame rate jumps back to a normal speed ON THE MAIN MENU.
I've already hit multiple places where the game's scripting is busted, and requires a restart to fix. This seems like quite a buggy release.
In addition, the camera controls were not tuned to full-sized console controllers, so the default right-stick speed is absurdly fast. Also, it doesn't seem to have any sort of acceleration, so it's somewhat hard to manage while moving.
