Hi green_abobo
Sounds like you are missing some game mods that you would help you.
Sounds like you playing the Stock game?
If you are new to SH5 look > > HERE << STEAM is not compatible with the essential application TDW’s Generic File Patcher
Steam Conversion Installation Instructions for SH5 Updated Version
Highly Recommended SH5 > The Wolves Of Steel Mega Mod > Includes KSDCommander And Working Enigma M4 Machine

I play custom difficulty, 88% realism. everything ticked except map contacts. gotta have some sort of point of reference, the best thing about it is using it to plot a contact's course, for the purpose of intercept.

You need at the very least TDW's NewUI mod in the Stock game.
This will give you access to his Options File Editor Viewer where you can customize your game to what you want to see in your game play.

currently on patrol, have to sink 100k with a whopping 11 fish.

Not strictly true as you have a time span on each mission and campaign which will allow you to return to base and re-arm.

This is no longer relevant when using one of the mega mods as the broken tonnage bar and campaign icons have been removed from the game.
The game works similarly to SH3 and SH4 with these removed.

Check out my SH5 Tutorilal thread in my signature as there is so much in there which help you to start enjoying your game.
There is no reason why you cannot enjoy SH5 as I and others players do.
