Capture one V4 problems

[woof75]

I find Capture one 4 to be quite slow, the conversions are fast enough but when I alter tone or colour there's a slight, maybe 2 seconds, delay while it renders it, it makes it really difficult to work if you can't see what your changes are doing in real time. Also I'm sure when I open an image in PS after conversion there's a miss match in colour. I really like the quality of conversion which is really incredible but I'm not sure this software is going to be usable for me.
