Hello, I want to use the WorldEd.exe from Arcanum, but it lags like hell. Especially if I zoom in or out. Sometimes, it doesn't show placed npc's until I restart the whole editor or it doesn't update the terrain map. I'm running the editor on Win7. Even in compatibility mode, no better running-behavior is achieved. To me, it looks like the editor (written in 2001) expects older cpu/graphiccard to speak to. My hardware is from around 2009, so I thought I build a computer with older hardware from around 2001, installing WinXP, hoping that I can work with the editor then. Might this work? Any other suggestions?
