Thanks for the quick reply Ralf
The fps was taken with generic vr headset (desktop mode) and with a riva tuner.
This was for test purposes.
What I noticed was there is a tremendous difference in framerate between Z3D and G3D.
Z3D seems to be closer to the performance of the desktop but G3D is literally performing 6 times worse. I know G3D renders double the geometry but almost 300 fps (Z3D) vs 40-45 fps (G3D) seems a little too extreme.
Other games I’ve tested were with non-official profiles but I’ll try testing more with official games and see what I get.
Thanks
