Planeshift uses a 3d graphics library called Crystal Space, and we work very closely with that group to make sure the features we need are in the engine. The library is under development, so sometimes it is unstable. Unfortunately, there was a bug introduced in CS which was only present for 2 days, but during those 2 days is when we issued the .004 release of Planeshift. This is most likely what is causing the problem with certain video drivers. You will probably just have to wait for the next release, which should be in the next couple months.
Sorry about this, but there isn\'t much we can do about it until Molecular Blue is ready. When it happens, we should be able to avoid this because I am sure we will do several patch releases of MB after we release it. Also, there is an auto-updater already completed which will be part of MB.
