I am so sick of Disney Support telling me to update my Grahpics drivers. I HAVE THE LATEST VERSION!!! My Vista laptop (Dual Core 1.8ghz with 3gb RAM and a dedicated 128mb GPU) runs PoTCO with next to no lag. I only notice a slowdown late in the day on a weekend.
The test server never lags, but then again I rarely see anyone else on there
Still lots of bugs, but in general I would say RAM RAM RAM, and a decent graphics card is what is required.
Disney will eventually get round to optimising the code for this Game. My other online pirate game has just had the code optimised and the game was so much better and no server upgrades required.
