SR1.1 installed smoothly and so far so good - haven't noticed any problems yet. 

But then I don't seem to have anywhere NEAR the problems other people have reported with P7...from initial install to SR1.1.

i7 6800 (6 core/12 thread), 24 GB RAM, 1 gtx 1080 ti (8GB Vram) + 1 Titan X (12GB Vram), PP11, Octane/Poser plugin, and a partridge in a pear tree.

Oh, and a wiener dog!
