GPU not at 100% use?

Minecraft is a CPU bottleneck of a game, you wont see your GPU at 100% used almost never in Minecraft. 

Recommended Posts

Hi, recently finished my first PC build

 

Ryzen 5 3600

GTX 1660 Super

16 GB 3200Mhz RAM

 

I'm running Minecraft with VSync Off and no FPS cap, and am running between 300-400 FPS, but my GPU is not at 100% utilisation. I have checked using MSI Afterburner and Task Manager.

 

Can anyone help as to why this isn't running at 100%, as it shouldn't be a CPU bottleneck?

Because it's Minecraft.

Assuming you're running dual-channel memory, your 3600 should handle the 1660 Super very well.

CPU is at 10%, is this because the load is only on one core?

correct. If you look at task manger with Logical cores so you can see all 6 cores 12 threads, you likely will see 1 more maxed out. This is the cause.

Great, thanks. Had a look with HWMonitor, 1 thread is maxed out rather than 1 core. Is it normal for this thread to change though?

As you can see the max load has been on 4 of the threads and keeps switching.
