Poor Minecraft Performance on AMD 6900XT

[Zurnar]

I recently got a new gaming setup, and I was disappointed in Minecraft's performance. As is, I am 'only' getting 170 fps when looking straight forward at 16 chunk render distance. By itself, 170 fps is not unplayable, but I just upgraded from a system with a 1070 in it and now have far worse Minecraft performance compared to that system. To be clear, this system is capable of running Warzone at more than 200 fps at max settings (no ray tracing), so there isn't anything shotty with the system itself, but particularly with Minecraft. I am curious if there are any great solutions to make Minecraft's performance much better. 

 

Here are the specs of my system to help troubleshoot the issue:

GPU - RX 6900 XT

CPU - Ryzen 9 5900X

RAM - 32gb 3200mhz 

SSD - 2tb M.2

PSU - 850 watts

Monitor - Acer Predator x34 (3440x1440)

Optifine installed? (if not do so)

Minecraft is known to be single core intensive and very inefficient, it’s probably a single core bottleneck and optfifine is probably the fix

Are you sure everything is up-to-date?

Driver, windows, etc?

Probably because AMD's OpenGL isn't great. If you just play Minecraft even a RX580 would perform simular. You can install Phosphor, Lithium and Sodium mods, these have helped me too (~100-200 fps > 300-800fps). You can also try Linux to see if this is the issue, since the MESA driver has better OpenGL support.

Ive never given Optifine a try for some reason, and I now get over 400 fps. Quite frankly I just like when things are OEM, but I can't argue with this much of a performance increase.

You should also enable everything in performance settings
