Although it is unofficial it is considered safe. It contains bugfixes and
improvements including an improved OpenGL subsystem.
As for why previous versions' OpenGL renderer don't work on Nvidia: it could be
either a bug in Wine or the OpenGL renderer shipped with the original version
is simply broken on Nvidia hardware. Btw. I get the same crash with
nouveau/mesa when starting Unreal Gold (v226).
