I have a 4K (~3800x2100) monitor and tried playing WoWS at that res and quickly gave up. I can't see the mini-map well enough or read the in game chat (often that's NOT a bad thing!!). The text is just too small, same problem with the mini-map.
There is a scalable crosshair in the mod package, an index mark will stay on the target as you zoom in and out. But that crosshair isn't as detailed as I'd like, I'm going back to "Tic-Tac" by Hootorez. If the target is at a 90 degree angle to you, and the time to target says 7 seconds, just align the 7 mark on the crosshair on the ship, adjust if the ship is particularly fast or slow, and fire. This is at max zoom, at less than max it won't work with the same number. That's why I'd love to see a combo of the scalable by W03L0BED and the Tic-Tac. Over time I've learn to adjust when the target isn't at that perfect angle.
