WHACKER'S PROFILE

My laptop specs

AMD Phenom II N620 Dual Core Processor 2.8GHz(x64)
GPU: ATI Mobility Radeon HD 4200 Series
Ram: 8G (with 7.74 usable)
64-Bit Windows 7 Operating System

No other programs are running while I play and everything is up to date(RTP, java, flash, visual studio, etc), yet the map is very laggy. I initially was getting a black screen and what was effectively a frozen unplayable game and the map fix you released seemed to help a small amount, but not enough. Then I started sleuthing and went into my power options and changed the system cooling policy within the processor power management section from passive to active and this made the game playable. Playable, but not ideal. The world map is still a slow, laggy affair that seems to be running at around 50% what it should be, but at least it doesn't black screen anymore. Oh and sometimes the minimap will disappear and the key item won't bring it back, so I have no world map. Hopefully some of this might help.
