Shortly after starting the game, I've got problem with giving orders and clicking on buttons (such as production of units or using special abilities) - everything is done with lag, sometimes it's suddenly interrupted (e.g. when I'm trying to match multiple units) and I need to do it again.

I'm playing under Windows 8.1 64 bit, I've tried with using dgvoodoo, as well as with compatibility mode and launching game as admin.None of these works.

Would be extremely grateful if someone knows the solution and could share it.
