I found troop control was greatly improved with a computer upgrade.
The minimum requirements are not correct. The recommended requirements ARE the minimum requirements. I'm not sure how the game even runs on the recommended requirements. But troop controls works well on a new i7 3770 The game still bugs out and crashes a lot....but troop control is greatly improved.
The game is not even remotely playable at the minimum requirements of a core 2 duo at 2.4. I had a core 2 duo overclocked a bit running at 3.7ghz and it was not playable.
Also on the graphics side, they made their own graphics engine, it is very inefficient. So it takes a lot more power than you might think. They have been working on bugs not optimization. Hopefully optimization is coming.
