All settings are lowest, I play with normal unit scale. The performance is not great, field battles run mostly ok. In siege battles the game lags frequently.

Any tips on increasing the performance (other than upgrading the hardware) are highly appreciated
Well Haudegen it is well below even minimum specs. Make sure all the AA etc is off as well as everything at the lowest. I'm not sure but if you can lower the resolution you shuold try.
