Stereoscopic Player 2.2 Beta
Stereoscopic Player 2.2 is still in BETA version but this rewrite is really good value for money as lots of features make it more efficient, more useful, and more user-friendly: SP2.2 offers support of Oculus Rift with head tracking and chromatic aberration correction, GPU acceleration for anaglyph modes, a stereoscopic cursor is available even in full screen mode.
The rendering engine has been fully rewritten from scratch and is now less resources-hungry than before. The last official stable version is still 2.1.4 but we are expecting the "official" 2.2 really soon.
Try before you buy
Stereoscopic Player is to 3D players what Microsoft is to operating systems: unavoidable! One advantage however is that the free version is working (with some limitations) so you can evaluate all options before spending €39 for a private license.
The 2.2 beta version is temporarily available on the 3dtv.at version history page.
