There probably would be some exceptions in games with high draw call counts, which might benefit more performance wise. Alternate eye rendering has more or less the same framerate per eye as single frame stereo, just with added glitches due to both eyes not being rendered at the same time, which can be fairly brutal if either you or stuff in the game moves fast.įor a developer it’s way easier to implement, but from a user’s perspective there isn’t really any advantage over proper single frame stereo except for a minor FPS boost since it has a little less overhead. Since each eye only gets updated every other frame the actual framerate per eye is half of what the FPS counter shows. The most important point here is that you don’t get twice the framerate with alternate eye rendering in the first place.Ī game’s FPS counter will show twice the framerate, but that’s highly misleading. Might come at some point as an option, but weighing the potential 10% effective performance gain against the inherent issues doesn’t really make it a priority. The actual performance gain after factoring out the misleading doubled framerate you see with an FPS counter would be about 10% in most cases since the method has slightly less overhead. In other words: performance wise proper single frame stereo at 45fps is the same as alternate eye stereo at 90fps. 90fps shown by an FPS counter with alternate eye stereo means 45fps per eye. The effective stereo framerate is just half of that since each eye only gets updated every other frame. The only real “advantage” is that it’s way easier to implement than proper single frame stereo.ĭon’t get fooled by the framerate a game’s FPS counter might display.

I got an android app called iDisplay which basically turns my tablet into a second PC monitor, I looked into the rendering software people are using to play games in side-by-side stereoscope only to see two programs mentioned, TriDef and VorpX, but they are both paid software, so I was hoping for any kind of free or open-source alternative I could work with.Considering the inherent glitches due to both eyes being rendered at a different time, the fact that it falls apart completely with any framerate below the headset refresh rate and the incompatibility with some headsets don’t make the approach look overly intriguing to me TBH.

I've wanted a good, cheap 3D gaming method for a while, and though I'd love to get an Oculus Rift once the consumer model is out, I unfortunately, despite my best efforts, am unemployed, leaving me with no income and very little cash to spare. I started looking into the possibility of doing a little project turning my 8' android tablet into a 3D monitor so I could then build a custom 3D headset around it for my PC games. Free TriDef/VorpX Alternative (Stereo 3D)?
