Trying out Kirsten’s S19 viewer for Second life and it is more stable and have a better frame rate than viewer 2.0. Both on my Nvidia and ATI cards.
Viewer 2.0 are more or less useless on many of the machines and have generally a very bad frame rate. So i am happy there are alternatives like Kirsten’s. I also use Snowglobe, Hippo, Emerald and Imprudence to find the best one to use. When you are in world for many hours bad frame rate and crashes are really not acceptable.
So lets hope Linden Lab makes it possible to use other initiatives even in the future.
