[SOLVED] How do I fix a FPS that is great with gentle movements, but quick ones and it drops to 18?

Hi,
A bit of a strange question, I have a PC at the moment which when playing games (most of the time Minecraft) has a pretty good FPS at around 80 to 120. This is when I move around at whatever speed, but I have to be gentle with the movements I make with my mouse, otherwise, my FPS plummets to around 10-20 at max. My PC hasn't always done this and it would be great to get some recommendations on what I could do to possibly improve this issue. As you cou8ld probably assume, this makes the game almost entirely unplayable.
Specs:
MOBO: Gigabyte B450M DS3H
CPU: Ryzen 5 3400G
Thanks for your time and I look forward to a response!

Minecraft is quite cpu and memory intensive. Still need reasonable graphics card which your igpu should do ok long as memory is fast. Memory speed of around 2933~3200 to help both cpu and gpu perform better and at least 16gb (2x 8gb) in dual channel.

If you upgrade ram make sure timings are even numbers not odd, Ryzen ram compatibility prefer even. Ie; 3200 CL 16, not 15 or 17.
