In about 50-90 % of cases when a character enters a town by joining/creating a new game or using a town portal, at the end of the loading screen, the game starts to show the mouse pointer and play sounds from the area, but then crashes immediately to the desktop.
So far, I’ve played to act3 in classic (pre-expansion) mode on bnet and the problem occurs with all three towns.
In the successful cases, where a town has been entered normally, with my video settings the game runs at (for me acceptable) 25-35 fps and from then on, I can keep playing and walk between various areas without problems. Only entering towns causes the crashes.
The problem occurs in both windowed and fullscreen mode, and with various resolutions. I have tried changing the desktop resolution and disabling scaling and running the “Scan and Repair” tool – it makes no difference. The in-game resolution scaling setting is set to 50 % and all other video settings are set as low as possible.
