As the title explains, I recently factory reset my laptop, first thing I did, install Minecraft, I made no other modifications to my system besides deleting some bloatware from my laptop, which was meaningless anyways, so, I ran Minecraft for the first time, and it was a pretty smooth experience, besides some non-affecting lag spikes, and some lag when I started up the server ( yes, i ran a server, hypixel to be exact ), but that was only for 5 seconds, and ran well, I played a game of bedwars, went off, did some things, and went back on only to realize the game was running absolutely terrible. The game had terrible lag spikes, I swear my game was running at 5 frames, it was stuttering horribly, it does this for 30 seconds up to 1 minute or longer, then gets smoother, but has lag spikes. Yes, my PC was on the plugged in for the best experience, and no other programs were running throughout both playthroughs, so I had no clue what happened.

UPDATE: deleting .minecraft fixed it, kind of, one again, the one time solution, was pretty smooth, was a bit more laggy on startup, but ran fine, a bit stuttery as well.

also, i got off, ran it again, same exact thing as my second instance, but the lag at startup, was shorter, but the stutters were the main issue.

UPDATE 2: I found a solution, I fixed JVM arguments, I'm pretty sure that's it, still stutters a bit, but not as bad, I think I got it though!
