@ItsJustCurtis Not trying to hijack the thread but I too will randomly have this issue still with all prerequisites installed. You mentioned that it depends on the machine you have. Well I have Ryzen 3700X, 16GB 3600Mhz RAM, and 3070 GPU. Its not the most powerful rig but it should well enough no?
At this time I have about 200 replaced cars with another 100 or so add on cars. No graphic or texture mods other than ENB. Note that all of my replaced cars are around 10MB or under in size. I usually don't have any ingame graphic loading issues either so am wonder if I just am reaching the game engine's limit?
