I have an AMD Rysen 5 3600x and an Rx 5700 XT plus 16gb ddr4 RAM.
In minecraft 1.16.1 I have "only" 100fps also medium settings and without shader or optifine. It should actually be 200fps and relatively high settings. I know that because I have a friend with the same pc.
I do not know what is the reason, can someone help me?
It doesn't matter but can be. That you have a lot of garbage in the background or that needs 1.16 more power
