Why zero everything The goal in this step is system. They make it very slow to open and complicated to use. Images processed full-size at 300 ppi for printing, 16-bit, in the Adobe RGB color space. The PPI value does not change any physical property of the image, it only sets metadata which describes the intended print size of the current crop (or the whole photo if there is no crop). The latter is great but has the problem of offering far too many facilities you will never ever use. By default, as of version 4.2.214, RawTherapee automatically detects and uses the same crop orientation as the orientation of your image - the 'As Image' option. Another freeby that works well (and quickly) is UfRaw which you can use independently of its parent GIMP. It does handle RAW files quite well with some limitations (mainly teh way it handles changes to White Balance), but its main attribute is that it opens almost instantly, and opens a selected file very quickly too and uses a lot less of your computer resources. The raw loading engine of RawTherapee is based on dcraw (RawTherapee 2.4.1 uses DCRaw 8.97). Different to other RAW converters it can use EAHD as demosaicing algorithm. All image processing is done in 16 bit/channel mode.

However, as a free alternative, Fast Stone Image Viewer is worth a look. RawTherapee supports JPG (8 bit), PNG (8 or 16 bit) and TIFF (8 or 16 bit). It has the problem that it doesn't recognise any RAW format more recent than about 5 years ago and I have to convert my A700 files to DNG (or TIFF or PNG) before I can use it. In fact I have an earlier PS CS2 which is far more comprehensive that PSE but which is much faster.

From that PoV I find RawTherapee is better than Photoshop Elements 10 which I do use. If RawTherapee is crashing, lack of RAM may be the problem. I don't have DxO but I suspect that like most of the more comprehensive programs it will be memory hungry and hence slow unless you have at least 4Gb of RAM. As you already have DxO you might as well stick with it.
