Couldn't find a topic with a similar question (if it exists, please provide a link). I installed Heroes 5 on a HP Pavilion dv5-1179er laptop (CPU: Core 2 Duo P8600, 2.4 GHz, graphics card: NVIDIA GeForce 9600M GT, RAM: 3072 MB, video memory: 512 MB) with Vista and DirectX 9.0c installed from the game disc. The game lags terribly and freezes on the map, making it unplayable. However, this doesn't happen in towns. And there are no such issues in the menu or videos, of course. What should I do? All previous Heroes games ran perfectly. As does this one, but only on a desktop computer.
