I am sort of severely braindamaged, so games like this is the only ones I can play. It does, however, contain a bunch of buuuugs/features, after all these years.
That´s why it only got a 3-star.
The version 2.28 works in Intel 945 with no artifacts for me; suprise.
This may be due to previous instalation of Doom from GOG which works on OpenGL.
I continue the game to find out if it will be so nice further...
