Could you try to turn off all working in the background elements: browser, scanner, printer etc. It is possible that game might be laggy if there is too many items working in the background.

Eador is very touchy when it comes to stuff running in the background. A browser with flash running, or with a big amount of tabs, a virus scanner, third party programs...

No matter how fast your machine is, if you have too much junk in your memory (too many processess), then it will slow down.

We encountered this in our tests. Each time, cleaning up the memory (closing all the unneeded things) made it work alright. Even as fast CPU's as i5 2500's had this issue.

If you close everything and still have problems, contact our support guys along with a dxdiag. It will inevitably land on my desk then, but with some much needed detailed info about your computer ;)

And before you ask - yes, graphically, it is a very simple game and it shouldn't do that. On the other hand, the amount of content inside is just mindboggling.
