HoMM3 HD is a mod (add-on) for the game Heroes of Might and Magic 3.

Hello, everyone. As far as I remember, the HD mod included a patch to reduce CPU load. Currently, it consistently uses 25-30% of my i5, sometimes up to 60%, and the cursor occasionally starts to lag, which leads to misclicks. Is this due to my computer or the mod? It seems a bit suspicious...
