Minecraft so little FPS with rtx2080ti and ryzen 7 3800x?

Hi

Hello I have been playing Minecraft for a couple of years and I also record with my PC. Up until now, I've always done this from my laptop and then finally bought a PC. When I tried it I noticed that I only have 30 fps on a maximum of 32 chunks with the same settings on my laptop, I have 60 FPS.

My PC has an AMD ryzen 7 3800x and an rtx 2080ti

And my laptop has an i7-9750H and a gtx1660ti

The drivers are all current and the temperature is okay with GPU 52 degrees and CPU 60 degrees. The utilization is also not fully utilized with a maximum of 30%.

I can no longer explain it to myself and hope that I can get help here.

Raise RAM

Thanks for the quick answer to my question. I increased the ram to 8gb but didn't bring anything and no change to 16gb and 32gb either

Increase ram speed (mhz)
