Ive been playing minecraft for 13 years or so [stopped counting on 13] (started playing the og versions in 2010) and lately Ive been stuck playing older version because 1.17+ lags my PC like HELL, even at 2 render distance and no smooth lighting, tho its odd that my PC can run ark with 60 FPS (OG), not to mention minecraft is in no way a taxing game on the PC…

here are my pecs (I give minecraft 10GB of ram to work with):

CPU Model: Intel® Core™ i5-6400 CPU @ 2.70GHz
CPU Info: Intel64 Family 6 Model 94 Stepping 3, GenuineIntel
GPU: NVIDIA GeForce GTX 950

any idea on what to do ? [IM NOT THAT OLD IM 18]
