Question FPS goes from 200 to 30 after 10 minutes

Hey, since yesterday I've had some struggles while playing Valorant.


My game runs really well for about 10 minutes around 160-200 fps and then it suddenly drops down to about 20-50 fps and the sound is also really laggy. When shooting it drops down to about 10-20 or when i try to turn fast, it's not really playable. It doesn't really go up once it dropped down. Sometimes it goes back to 120fps for a solid 20 seconds and then it drops back down. When I first started playing Valorant like 2 months ago I had around 120 fps all the time and it never dropped down to less than 80. I thought it was my GPU overheating at first but it was at 57°C when my frames dropped. I use performance mode on my Laptop as well. The game never really uses more than 10% of my GPU or CPU but it usually uses about 2000MB of RAM (This is when I have good FPS but also when I have bad FPS).

My laptop specs:
CPU: Intel Core i5-10210U
Memory: 16GB RAM (Usually uses around 5GB of RAM when I'm not gaming)
GPU: NVIDIA GeForce MX330
(I have a Lenovo Thinkpad T15 so you can google any other specs if you need them)

If you have more questions feel free to ask them, any help is appreciated.
