11 Gb VRAM insufficient for 5+ characters for Iray Rendering???

Well iray can do a good job if you give it enought time to get a good convergence. But this can take a lot depending on the scene and your card power. So using a denoiser is a simple way for faster renderings. Personally I'm a rush guy so I guess a denoiser is the only way to go for my temper LOL

EDIT p.s. actually I'm exploring real-time PBR with Blender that will come out in the next release (actually a beta branch) and it sounds quite interesting for fast animations
