Why can't I turn on shadows with a brand new Nvidia GeForce GTX 550 Ti?!

The viewer probably doesn't recognize the few weeks old GTX 550 Ti. Raise the graphics to ultra first and it should let you enable shadows then.

If you have your graphics set to ultra and it still doesn't work, try to disable anti-aliasing. You might also want to try out Phoenix or Imprudence if Kirsten's doesn't start up.

Kirsten's viewer does not yet include the Nvidia 550 Ti in the gpu_table so it's not recognising the card. Unlike Second Life's official viewer, which is likely to load at low or medium settings for new cards it doesn't recognise, the installer in Kirsten's S21(6) invokes minimum hardware requirements so it is simply not allowing the application load at all.

You should still be able to use S21(5) with no problem and perhaps you can disable this hardware check in S21(6) with the viewer parameter --noprobe but I'm not sure how Kirsten implemented the hardware check.

You should have Hardware Skinning ticked for Lighting and Shadows.
