I have a new graphics card GeForce GTX 760 which can handle all games at ultra settings. While logging into SL viewer (3.6.4) I get the message "your system contains a graphics card that SL does not recognize. This is iften the case with new hardware that hasn't been tested yet with SL:" I can't enable advanced lighting on the graphics tab, neither depth of field and ambient occlusion. My system can handle it very well, I treid it with a third party viewer. So do I have to wait until SL tests this graphics card or is there a work-around so I can enable advanced settings in SL viewer? Edit: Thank you for your reply valerie. I have updated my drivers immediately after setting up the PC and card, so all drivers are up to date, that is not the problem :(
