You can configure the game to your taste, if you start the Option File Editor Viewer, for example you can chose the SH3 UI and dials. Be sure to start the game in Admin mode by setting it in the game shortcut.


To correct possible grafic glitches, set your Nvidia Control Panel (or equivalent AMD) > Scaling Options > Fullscreen. If still it doesn't help, then set the scaling options to GPU instead of Display, that should help.


Be sure to read the TWOS notes & tips in the documentation, TWOS is set to realistic play without Real Navigation by default, but you don't have to play it at high realism, again you can set this in the OFEV mentioned above. For example, you can play with Auto-TDC which is much easier. For that, disable Manual TDC in the in-game options, open the OFEV (read the doc about how to use the OFEV), go in the XO TDC tab and disable the last option (disable manual TDC).


In the sticky posts here, THEBERBSTER has some very useful in-depth guides that you want to check, e.g. how to fire your torpedos, how to navigate and find targets with instruments etc., plus there are useful tutorial videos about TWOS.


Third-Party mods: NOT advisable to use with TWOS because most of them are not compatible with it. And then: what do you want to change, you don't even know TWOS yet? You can do most changes in the OFEV or in the in-game options. Besides, TWOS comes already with optional mods that you can load via JSGME.
Exceptions: German language patch or those mods which EXPRESSLY mention that they are compatible with TWOS.
