Torpedo settings...Real life?

Well, a quick google search turns up this;

http://www.fleetsubmarine.com/tdc.html

Relevant part is "In addition to the standard angle solver" - the function of calculating the lead angle was such a basic part of the system it was only mentioned in passing. If it wasn't programmed to calculate the lead angle it wouldn't have been very useful, unless the ordinance that you're shooting has a velocity of 186,000 miles per second it's rather pointless to shoot at a moving target where it is now rather than where it will be.

Fire control computer on a modern tank is a good example - there's a wind speed and direction system on the turret, if the gunsight automatically compensates for crosswinds why would you need a readout to tell you what the crosswind factor is? My thinking is if the German TVR had a separate readout for lead angle more power to them, if the TDC didn't have a dial for that it was probably because it would have been redundant.

I've used both systems, I currently have a German ATO career and a US Pacific career active in SH4, and even though I don't use the PK much I still find the TDC easier to use simply because the "own ship" and "target" dials one above the other makes it easier to visualize the situational awareness "picture" for the approach. I have used the "angle off" method where you estimate the intercept angle, set the fish for a zero gyro angle, then offset the scope 10 to 15 degrees and fire when the target hits the crosshairs, but that's usually reserved for the S-class which wasn't supposed to have a TDC in real life.
