1. I recommend utilizing action set layers. For example when I press L4 and then touch trackpad it will bring up F5/F9 radial menu that I can use to quick save or quick load.
2. Also and this is a BIG ONE. Set your right stick outer zone to 1 and bind right-click to it. That way whenever you move the right stick, the right-click is automatically pressed and you can move the camera much like in normal games. This almost completely fixed controls for me. I use right trackpad as a mouse cursor.
3. Set left stick not to WSAD but to WSQE.
4. Set d-pad to map/inventory/journal etc.

TDP to 7

Install FtG UI mod to fix the fonts.

1. download it from Nexus Mods
2. add DAUpdater.exe (found in the DAO folder) as a non-steam game.
3. set launch command of DAUpdater.exe to STEAM_COMPAT_DATA_PATH=the_compatdata_dir_for_dao%command% (change the_compatdata_dir_for_dao to compatdata folder path of DAO ultimate edition, folder should be named 47810 - but you need the full path)
4. now install FTG UI mod with the DAUpdater
5. In FTG UI folder find the .exe file that lets you configure the font sizes, add that as a non-steam game
6. repeat step 3 for the confix .exe file (same path, just copy paste the launch command)
7. Experiment with font sizes, I use something between 20 and 30.
