Necro campaign is growing! I began playing it and while I find it pretty intense, it's fun :)

I strongly recommend turning off dynamic lights on average PC as enormous amount of explosions and projectiles with produce insane amount of dynamic lights and that will bog performance down (I couldn't play it on my PC). Users with higher end GPUs can turn on deferred rendering and enjoy new campaign in all its beauty by bringing down in-game console ( Shift + Esc ) and entering cvar:

r_shadow_deferred 1

It worked wonders with my GF 670 GTX and from now on I can enjoy playing SS:BR with dynamic lights at no performance cost! :)
