I'm not 100% sure so don't take my word for it

The reason for the slowness is because compositing/acceleration does not work
with xinerama

There has been a patch recently in the xserver that allows for xinerama to be
used in conjunction with compositing. Nevertheless there could be some bits in
nouveau that need updating

In either case you will not get any acceleration if the total resolution
exceeds 4096x4096
