Is possible to disable composition for fullscreen apps ?
I testing Ubuntu 12.04 LTS updated beta version but I bothering with poor performance in 3D apps even with nvidia driver.
I check that turning Unity3D off helps, so I think main problem is composition. There is cca 30% slower performance, not even FPS but small lags. With Unity2D all is fine. With KDE and composition it is good, under Unity3D not. So maybe there is still some regression in unity 5.X or composition manager.
Is possible to turn off compositon while 3D app is running in fullscreen as with KDE's KWin ?
