Possible related nvidia forum tread http://www.nvnews.net/vbulletin/showthread.php?t=127984 , because I guess this happens only on machines with 4GB ram or more.
Did anyone have the problem with less memory?
Yes. With mem=3g and preloader patch World of Warcraft stil crash after a while. But with it i can play much longer.
I have 6 GB ram, I experience the issue if I boot linux as is. As told above the provided patch doesn't help, and after reading it I don't see how it could solve anything, but I would be glad to have an explanation for my understanding.
Using mem=3G or mem=4G, the issue disappears completely even after 4 hours of World of Warcraft.
I have reproduced the issue with the minimal test case provided on nvnews forums (see comment #33), it looks like it is related to using a 32bits opengl program in a 64 bits OS. Even glxgears (32 bits) shows the issue. For me the issue could be related to the fact that the nvidia driver uses ram for texture above the 4G if such ram is available, leading to issues when running in a 32bits userspace. Anyway it means the 32bits implementation of opengl is faulty on 64bits hosts. Maybe its just the wrapper, maybe its the driver, but its probably not wine.
The problem also occurs with a 32 bit OS, so it's not 64bit specific.
