AutoDesk Showcase rendering

I must have  tried at least a dozen "real-time" render programs by now but forgot to actually look and see if Autodesk had one of there own,I stumbled over Showcase while looking at game engines and another rendering program called Marmoset on You Tube.Showcase is a hard program to judge,it has tons of features and presets,its got hdri lighting and a library of materials to play with but compared to some of the other software I tried it isn't particularly fun to use.It might be strange to describe it as not being fun but I think the best programs encourage you to play around,in the case of realtime renderers slapping textures onto objects they clearly don't belong to and looking at the results.Compared to Lumion the renders do come out more realistic and with a less like a game engine.The program is good though,there is huge amount of options and you can create turnarounds and movie's and even add animation but what stops me going back to it is that performance wise its below some of the other software I tried.On my laptop it ran very slow when I tried upping the details,if you have a good computer give it a go for sure but there's quicker realtime software.

I imported my train model and was pretty happy with realtime results
but beyond this level of detail my PC came to a standstill.

Rotating camera on this scene it looked fair,one thing I did notice is
that Showcase doesn't support .obj importing
