Here you go… Some of this may well have been over the top, but almost none of it is really that difficult to do, and if its the difference between getting the sim running or not, it is probably worth doing the extra steps.
I will also add that the sim has been pretty stable for me since doing this, with very few problems - think I have experienced a couple of PC crashes, but I suspect this maybe due to CPU/GPU temps. I tend to whack up fans speeds when I use the sim now.
Anyway I hope this helps…
