So I'm playing Diablo 3 and I love it by the way. However, sometimes the game goes into slowmotion mode and I have no idea why.

At first, I thought it was my computer being bad enough but it meets the rec and I sat everything down to low / off.

Still happend, checked my internet connection.. it's fine. However, high MS in D3 _only_.

So whats the problem with this "slowmotion" thing?
Intel core 2410M 2,3 GHz
Nvidia 540M
8Mbit / 2mbit internet.

Any thoughts on how to fix it?
