Yes, this is most likely not a laptop issue, especially if you say that in other, even more powerful games, you have about 100 fps. Fps drops can be due to various reasons, and the first thing I want to ask you, do you play in single player mode or on online servers? If on online servers, I recommend changing the server, since most of them are poorly optimized today. You can try minecraft prison servers. If you play only in single player mode, then the problem is most likely in Minecraft itself, the way it builds the world. If you didn’t know, minecraft procedurally generates the world, and this is very resource-intensive, and as a result, fps jumps occur.
