Even if you turn off all adjustment modules you end up with poor detail and artifacts if you use DxO Optics Pro to open Sony RAW image files. As far as I can tell, it just can't deal with Sony RAW images.
My experience has been very good using DxO Optics Pro--at least versions 9, 10, and now 11, and I think I started with 8--to process Sony raw files from the A580, RX100 (original), and A7 II (plus my old Konica Minolta Maxxum 5D). I have also used Lightroom (5 and 6), Sony Image Data Converter (versions going back several years), and Capture One (8 and 9 and I think 7). In my opinion / experience, DxO Optics Pro is overall the best. For any given picture I might slightly prefer the color I can get from IDC, or the lens corrections I can get from LR, but overall DxO is my favorite.
So there appear to be three possibilities: (1) you are not actually turning off some setting that is doing something odd, (2) what you are describing as poor detail and/or artifacts is just some difference in default sharpening and/or your taste / perception, (3) you're using too much lossy compression to save the worked-over file, and/or (4) you've discovered a bug particular to your camera, lens, and/or workflow.
Why don't you post (1) a link to your raw file(s) that are causing trouble and (2) a 100% crop of a processed file that you think shows the artifacts? I, and probably some others, would be curious to see whether we find the same problem(s). Also, if you want to post a 100% crop of a file from another raw converter that you think does not show the problem, that would be very helpful.
