ReSharper C++ is joke or real?

Hi

We bought the Resharper C++ Plugin for VS2015 ... but i don't know this is a bad joke or real??

When i open the solution (~300 files, ~20.000 lines) the resharper start to updating files ... always, and it's very slow .. (it wroted in awk?) ...

Ok, started the usage ... i press the Navigate to ... Resharper thinking ... ? :) really? ... why? (i press F12 in Studio and it switch immediatelly ...) ..

And now .. i change the !!comment!! in the file, resharper can't colorize the file .. code completion not working ... 

I think i need back my money and start to use VAssist again ... this is just a joke
