What to do to stop falling into the hole in FiveM?

I’m starting to play FiveM now and I’m having some problems. I think it’s my graphics card or processor, I don’t know.

Sometimes when I drive very fast on a road, I end up falling into an invisible hole that people call the “limbo”.

It also happens when I’m on foot or going slowly in areas with a lot of mods, like the square, pier, etc.

I’ve tried everything. But the usage percentage of my graphics card is low compared to the CPU usage.

How do I make GTA V FiveM use more GPU than CPU?

People call this a bottleneck or something like that.
