The 64MB limitation was a long time ago. Wine has been changed to try to detect your video card and guess how much memory it has. In case it guesses wrong, here is the registry key: HKEY_CURRENT_USER -> Software -> Wine -> Direct3D -> VideoMemorySize See http://wiki.winehq.org/UsefulRegistryKeys For example: if the card is a GeForce 7600GS, those usually have 256MB and that will be wine's guess. However some have 512MB, in those cases it may be necessary to set the registry key manually.
