Graphics card laziness?

In Minecraft I have normal with Shader 90-120fps, my monitor has 144hz and G-sync ensures that there are no cracks in the picture.

When I play Minecraft with a shader, I go to a map and initially have 120fps, but after about 10 minutes I only have 60fps. How can that be? My graphics card manages more than 100fps, why does it only show 60fps after a certain time?

Graphics card: GTX 1660 Super

I can hardly imagine that a 1660 can run over 100 fps. My old 1060. When starting a program or game it also has around 150 fps that then goes down. At least that's my experience.

So is that normal?

I don't know but I have the same "problem"
