Low FPS in FiveM despite RTX 4070 Ti

FiveM Discussion Bug Reports

Hi everyone,

I’m having the following issue:

  • RTX 4070 Ti
  • i9-9900K
  • 32 GB RAM (4×8 GB, 3000 MHz)
  • 1440p
  • BIOS is up to date

In FiveM I only get around 40–80 FPS, while GPU usage is usually only around 25–50%. CPU usage is around 35–60% and the CPU boosts correctly to about 4.7 GHz.

Even if I lower the resolution to 1080p, the FPS and GPU usage stay almost the same.

The GPU works perfectly fine in other games and gets properly utilized, for example Battlefield 6 and Assetto Corsa EVO on three monitors with high settings. PCIe is also running correctly at x16.

What confuses me the most is that with my old GTX 1660 Ti I sometimes had around 130 FPS.

FiveM Resmon looks mostly fine, although the profiler showed some occasional script spikes of around 14.5 ms.

Does anyone have an idea whether this could be caused by FiveM/server scripts, a CPU/main-thread bottleneck, or a local FiveM/GTA setting?

GTAV and FiveM by proxy are single-thread heavy, so you’ll pretty much never see 100% CPU usage (if you did it’s a cause for concern lol). Instead of looking at the overall CPU usage percentage look per core/thread and see if they’re being maxed out

I had made sure that the CPU wasn’t getting bored
