--- Comment #4 from nob.dir.info@gmail.com 2013-06-30 06:52:07 CDT --- New hint: Using wine in "real" 64-bit(I mean with wine built with --enable-win64), I managed to use ~750 Mo VRAM with Guild Wars 2 in 64-bit mode (desktop using ~100 Mo), and there was no crash. StarCraft II with this version of wine also stopped crashing after one or two games/missions.
However, Skyrim still crashes, even with 64-bit wine, so the bug seems to be really weird.
