Lumen RT - Stereo not working properly

Ive tried using this option (stereo output) on multiple installations on different PC's but the stereo output seems a little bit broken. Basically adjusting the convergence has zero effect which means that the scene is constantly "focused" on a position which is about 5 metres in front of me. It does what I adjust the convergence to it has no effect on anything at all! -Anyone else had this problem?
