Well, this is weird.
As stated in my posts up above, I have tried as mega mods both The Wolves of Steel (TWOS) and Wolves of the Deep.
I have two laptops that both run Windows 10 and have both been recently reformated, i.e a fresh Windows 10 install.
Laptop A runs an Intel Core i5 with a Geforce GTX 560M graphics card.
Laptop B runs an Intel Core I7 with a Geforce GTX 860M graphics card.
I downloaded SH5 from Gamersgate on both computers, updated them to version 1.2 then followed the instructions left by the mega mods authors.
SH5 with either mega mod starts on both computers without a problem, I can even start a patrol, usually Danzig Bay.
This is where it get's tricky.
On the older laptop, with the Geforce GTX 560M graphics card, SH5 runs perfectly.
On the newer laptop, with a more powerful Geforce GTX 860M card, everytime I open the navigation map, either on patrol or in the commander's briefing in port, I get a sound semi-freeze, and a complete crash, not a CTD, I literally have to manually restart the computer.
As per Vdr1981's original post up above, "CTD scenario 5", I have disabled Render Patches in the TDW Generic Patcher. Sadly, nothin' doing.
Must be some incompatibility somewhere. Any ideas anyone?
