@SomeonePLaysMC Good suggestion, but new worlds created on 1.17 are running buttery smooth, as is the existing world on 1.16.5. I am only facing this issue when upgrading existing 1.16.5 worlds to 1.17.
@SomeonePLaysMC Ok, so I did what you said. I upgraded my 1.16.5 world to snapshot 21w20a(because loading of old worlds was disabled in 21w14a). And, my game was running perfectly in 21w20a! However, when I further upgraded it from 21w20a to release 1.17, the game was stuttering, but this time it was running a little bit better than last time when I directly upgraded my world from 1.16.5 to 1.17. However, the lag is still unbearable in release 1.17, albeit a little bit less.
@SomeonePLaysMC Ok, so I did exactly what you said. My world was running smoothly till Pre-Release 2. After that, it gets interesting. I will break it down version by version after Pre Release 2:-
Pre-Release 3: Little laggy, not as bad as 1.17 but still a bit unplayable.
Pre-Release 4: Still laggy, but less lag than Pre Release 3, fairly playable.
Pre-Release 5: Unbearable lag, just like 1.17.
Release Candidate 1: Unbearable lag, just like 1.17.
Release Candidate 2: This one performed a little bit better.
So, someone made a comment asking me if MC-219639 relates to my issue, and then promptly deleted their comment. It seems like yes, it does relate to my issue. Here's the link to MC-219639:-
MC-219639 Performance loss after using OpenGL 3.2 core profile - Jira (mojang.com)
Edit: It looks like MC-219639 might not relate to my issue, as per ampolive.
MC-228302 doesn't seem to directly describe my issue, because I didn't break any shut trapdoors, that might result in lag(if I understand this correctly). Anyways, here's the original zip file of my 1.16.5 world(before it was upgraded to 1.17):-
[^NetherLand.zip]
Edit: It doesn't let me upload my world, because the maximum size limit is 10 mb.
@violine1101 The minimum requirements for Minecraft stated in the website is Intel core i3 3210 @ 3.2 GHz, 4 GB RAM and Intel HD 4000 graphics. My PC does meet the minimum requirements!
Ok, thank you so much for investing your time in this to help me out. I am also considering using Sodium, Phosphor and Lithium mods when they are released to get even better performance.

I deleted all the datapacks from my world's datapacks folder and opened the world in 1.17. Still lagging like before.

Ok, here you go(this was the original world last saved in 1.16.5, before upgrading to 1.17):-
