Tried renaming megashaders and fxo individually. Got the compiler error on megashaders so then I tried fxo rename and game would freeze at splash screen. This is either launching from Steam or from my desktop shortcut with only Steam runtime in the background.. No go. I'm done. I can live with what I have now and this is taking to much time from having fun :-).
And truth be told, this is almost like I am trying to pad my post count here anyway !
