Greetings, I recently installed a GT 620 in replacement of a GT 220 which failed after nine years. The original GT 220 was O.E.M. by HP ( HP PN: 533212-001). The 3D application was installed with the GT 220 and never used the program. No problems were ever associated with 3D that I’m aware. Can I safely disable the 3D Vision and Controller drivers in the new GT 620 graphics card I installed. I was unaware of the aspects relating to 3D, prior to installation. Secondarily, I’ve been hesitant to uninstall without knowing if the drivers are bundled within a container, adjoining the graphic drivers. Finally, the Windows Experience Index changed upon installing the GT 620. The GT 220 had a Windows Index of 5.9 O.E.M. After installing GT 620, the Windows Index dropped to 4.1. I uninstalled the GeForce Experience and re-ran the Index rating, as the score was upped to 4.8. The 3D business gaming and graphics graphics performance was originally 6.5, then dropped to 6.3 after installation of the GT 620. Desktop performance for Windows Aero was 6.5 O.E.M., then dropped to 4.1 after GT 620 installation and was upped slightly to 4.8 after removal of GeForce Experience. https://www.bleepingcomputer.com/ne...-support-for-3d-vision-in-game-ready-drivers/ I would very much appreciate all assistance relating to the aforesaid. Thank you very much.
