graphics card hits 100% usage in games and the PC freezes

Hey,

I just started playing GTA RP, the famous FiveM. I put that little bar up top because I like to see the stats: FPS, GPU usage, CPU, temperature… so far so good. I can join servers and play normally for 20–30 minutes. 80 FPS, GPU at 45%, and I don’t remember the CPU usage now, but out of nowhere the GPU usage jumps to 100%, my character starts moving in slow motion, the PC freezes. I can only get out of the freeze with Ctrl + Alt + Del.

I searched on the official FiveM forum and people there say it’s because the servers I play on have a lot of mods, and that my card, which is a 1050, might not be able to load everything fast enough.

What I find funny is that my PC runs GTA V at over 70 FPS without any stuttering or anything. Why does this happen on FiveM?
