Framedrops since Update 1.16.200

Hello,

since the update 1.16.200 (Render Dragon), minecraft is not using my gpu correctly. I play on windows 10 without any ressrouce packs (vanilla). Before the update, ive got about 144 fps in every situation (48 chunks loaded). After the update, in some areas with many buildings, the fps drops at 40 and lower. And yes, i mean without raytracing!

The best thing is: If i enable raytracing, my frames are higher and stable at the same place. About 60-80 fps and no stuttering...
But i don't want to use raytracing! 

My wifes Laptop and all of my friends don't have this problem.

My PC:

• i7 4790K (iGPU deactivated)

• RTX 2080

• 16 GB Ram

• SSD

• Windows 10 x64

All drivers are up to date and windows 10 is also up to date.

So this pc should run minecraft very well and if i enable raytracing, it does. But not without it. My settings are currently at the lowest render distance for my pc (8) and it stuttering like .... . The CPU and GPU usage is realy low, there is no bottleneck. 

It is stuttering, textures loading slow, and so on...
Please fix this bug!
