Hm, grabbed this game from the sale, and so far have had no luck getting it to run correctly. Here are my issues:
The main issue is the mouse lag. Sometimes the mouse will move exactly the distance it should, but most of the time it barely moves, and jumps around. The problem starts after loading a game, but then persists into the game menus after loading. Changing the resolution fixes the issue in the menus, but then the problem re-appears as soon as I get back in game

Problem number two is graphics flicker. If I stand still, it's fine, but as soon as I start moving ingame, all of the set pieces (trees, the palisades at the beginning of the game) have a noticeable flicker that gives me a headache.

Together these issues are making the game unplayable, and this game really looks interesting. Any help? I've found nothing searching through the forum so far.

I'm having mouse lag problems as well. Not in the menus, only while I'm playing in high density areas.

This game seems like it was made for me so any help would be greatly appreciated.

I noticed using a new mouse fixed my issues. Not sure how to make my old mouse work though. This is the only game my mouse wont work with.
