To elaborate I have played with this exact modlist for 4 days (and around 20-30 hours). I did not face any CTDs, freezes, heavy stutters etc. Not even fps drops. No ini files were changed, no new mods added, _______________ Stage 1. I enter any location from the Rockwel Pursuit mod's Colorado part. The game loads this random location. I enter another random location. The game loads it. I enter another random location. The game freezes on loading or gets into an infinite load. I have to end the prosess with task manager by alt+tab and arrow keys to locate the FNV prosess on the minimized window and then terminating it. I enter the game. It gets to the NCR ranger with music and all, but never loads the main menu. OR It loads the main menu in 2 minutes (usually only have to wait 10 secs), is very slow and when I click "continue" it freezes not even letting me press "yes" _______________ Stage 2. This behaviour persists for a couple of game.exe loads(?) or some time(?) or until I reset my PC(?) All above work. After waiting/entering and exiting the game a couple times/reseting my PC the game loads. It works perfectly, loads in 10 secs, no slowdowns, no fps drops. I continue playing the mod. I get back to Stage 1. The story repeats itself. _______________ I do not need exact help or ways to fix this, it's just that in my 520 hours of playing I have not seen the game do this. What I need to know is: can a mod physically do this? What even could cause this?
