No, it's not the recomended, but I simply can't imagine SL without sun/moon & projector shadows, that's insane. It also doesn't enable Ambient occlusion, which, by the way, if ANYONE is having a simillar 'issue' as I am then
◙Dissabling Ambient Occlusion gives a 10-20 FPS boost, while hardly impacting the visual aspect of the game.
