G'day midnightrider.....Been down the install it yourself mod path for a couple of years.
I would get nearly to the end of a mission only to start suffering random CTD's.
In my latest debacle after having half a million tons under my belt, my SH5 decided to call it a day!!
I was at the point of giving up on this game so I deleted everything, reinstalled fresh with "The Wolves of Steel" megamod to give it one last try and it's left me wondering why the hell I didn't do it sooner!!
Most of the best and latest mods are included and tweaked for stability and gameplay.
Do yourself a favour and go down this road and you'll learn how to play the game instead of learning how to continually fix it
I can't recommend it highly enough!!
Best Regards.....Kev*
