Thanks Aktungbby and Katze, Yes I had enabled the generic patcher and didn't realise there was a newer version of TDW FX update, I will try that out
Also noticed my graphics (while crisp) are looking quite cartooney, night seems to glow completely and there is a high saturation of colour on everything, the flags look radioactive ha ha.
Will try getting TDW's FX update and see if that fixes the circling torps. Or I will just remove the torp patch from generic patcher!
