I am getting a black screen with Geometry 3D in some titles. Changing to Z3D fixes it. With one title, by changing the resolution to 4K (native desktop resolution), Geometry then worked (i.e. no more black screen), and then I was able to change it back to the preferred resolution. My question is there some rhyme or reason to this as to what is causing this? I am experiencing the same thing with another title, and this time changing to my desktop resolution (4K) did not fix it. All of these titles are supposed to have working G3D.
