I used my old method to identify targets more correctly - by improving the Anti-Aliasing available in the game. In Wolfpack (NVIDIA) Anti-Aliasing is a little inaccurate and you can see jumping/blinking masts and incorrectly projected ships on a FullHD monitor, even at highest AA setting.
What should you do? Increase the resolution above the native resolution of your monitor. This resolution will be scaled to the native one. Here's the effect you can get with this method:
and the options of the NVIDIA control panel, where to do this (polish):
Of course when you change resolution to 4K in older hardware, you may feel a drop in performance, but in my case the resolution increase to only 2560x1600 makes it much easier to recognize targets from long distances and this change does not affect game performance.
Note: before running Wolfpack you should change the resolution (to the new one) in Windows itself, otherwise the change in Wolfpack will not result in an improvement in quality. When you add new, higher resolutions, read the messages on the screen carefully.
