I've been facing this problem after updating to 1.62. You see, whenever I go into new scenes, and if the loading page is taking longer than usual, I can be pretty sure that the next area I'm on won't be loaded completely. By this, I mean that certain areas like parts of a corridor, insides of a small room, or areas near any doors.
Weird things I encounter are unloaded areas are like black patches, running longer than usual to get through black patches, floating doors/NPCs/loots, fighting in darkness... I can see things like doors/loots/NPCs when I 'tab' the keyboard.
It's still frustrating to me when I play SP in the campaigns, but it really gets me when it took forever to load the next scene when I play MP in a PW till I gave up and rebooted my comp. (Hope my party members are not mad at me for disappearing!)
I now have all 3 expansions now. My comp specs as follows:
Operating System: Windows XP
Processor: Pentium 4 1.9 GHz
Memory: 512MB RAM
Hard Disk Space: 25.9 GB free
CD-ROM Drive: SONY CD-ROM CDU5221
Driver Version: 5.1.2535.0
Video: NVIDIA GeForce4 MX 440 with AGP8X
Driver Version: 5.6.7.2
Sound: AVANCE AC97 Audio
Driver Version: 5.10.0.3840
My graphics card is already updated from NVIDIA'a site, but the problem persists. Now I'm at my wit's end. Please shoot advise from all directions.
Thank you for reading!
