Hi, I start RT in a command shell as you suggested. It takes 3 min to get a white window and an additional minute to have the picture icons displayed.
There is no message whatsoever from RT in the command shell.
Within RT it takes an additional 48 s. to get the options window on the screen.
I also looked at indexing. I disabled the indexing service and started RT and the start time remains the same at around 4 min. I reactivated indexing, rebuilt the index, and the starting time is still at 4 min.
People might think that I have huge problems with that PC, but it works fine (4 cores, 2.5 GHz, 8 GBytes RAM, SSD). Before RT, I needed to use SilkyPix on Windows to process my raw files. SilkyPix starts in 10 s.
So I will try again in a few months. That's not a big deal for me since I use RT in Linux anyways and I am so lucky to have RT on Linux in the first place.
