My cars are disappearing/de-rendering

After reinstalling Beamng, I could notice that when I spawned more than one car, the ones that were not in focus, derendered.For example: I have a habit of creating races with the game's AI and watching the cars compete. But for some reason, when I'm watching a car, or a trio or pair, the other cars that are not in focus simply derender! I don't understand what's going on, I've done everything, I've increased the traffic limit, I've cleared the cache, I've done several things, but still the cars disappear out of nowhere. I just want to understand why this happens, it's so cool to see the cars racing and count how many seconds it takes for second place to reach first

 

Have you tried safe mode?

 

I didn't know this mode existed, how do I activate it?

 

In the launcher, click support tools. Then click: Launch (safe mode).

 

I just tested this and the cars didn't derender, I thought it was some mod and decided to go check it out, but even after deactivating all the mods in the repository, the vehicles continued to disappear

 

Even after disabling all your mods, there can still be an issue with your userfolder. Here's something you can try:
- Copy your userfolder to another location on your computer
- Delete the original userfolder that you made a copy of
- Launch the game (this will create a new userfolder)
- After closing the game, you can move back anything you want to keep from the copied userfolder (such as mods, configs, settings, etc.) to the newly generated userfolder.

Keep in mind that something you move back can cause the issue to reappear, so make sure to check after moving something.
