The problem with playing at 1xTC is that you tend to ignore the computer a lot, and hence can actualy miss more stuff than if you play atentively at reasonable time compressions like 128xTC. Examples of this are people going to the bathroom, going to eat, watering the garden or any other activity that might make you miss the exact moment when your sub get's bombed by a plane
Not that using time compression is... completely satisfactory... let's hope SHIV is improved in this regard
