Packet loss, entity desync and major FPS drops when near many players

What is the issue you’re having?

Hello, I’m having a serious synchronization/packet loss issue in FiveM, and I’m hoping you can help me identify whether this is a FiveM/OneSync issue.

What happens:

My packet loss starts around 7% when I join and can increase to around 18–25% in crowded areas.
My FPS can drop from around 100–120 FPS to 30–40 FPS at the same time.
Players and vehicles start disappearing and then reappearing.
Sometimes leaving/entering an interior temporarily fixes the issue.
My GPU usage can drop to around 20% while this is happening.
The problem becomes much worse when there are many players nearby.
I don’t experience the same issue in the same way on other FiveM servers.

I have already tried changing graphics settings, network/adapter settings, DNS, IPv6, clearing FiveM cache, and other common troubleshooting steps, but the problem still happens.

Could this be related to OneSync/entity streaming/network synchronization rather than my PC hardware?

I would really appreciate it if someone could help me

Additional comments

My packet loss is usually around 7% when I first join, but it can increase to around 18–25% in crowded areas. At the same time, my FPS can drop from around 100–120 FPS to 30–40 FPS.

Players and vehicles start disappearing and reappearing, and sometimes entering or leaving an interior temporarily fixes the issue. My GPU usage also drops to around 20% while this is happening.

I have already tried changing graphics settings, DNS, IPv6, network adapter settings, clearing FiveM cache, and other common troubleshooting steps, but the issue remains.

The problem seems to be related to crowded areas/high player counts. I would like to know if this could be related to OneSync, entity streaming, or network synchronization.
