When my minecraft has TPS of 20, but low fps, what does that mean?

I am trying to profile my minecraft, since I only have around 10-15 FPS, despite, IMHO, having a fast enough computer. Using TickProfiler, I can see that I get 20 TPS. I assume this means Entity ticks aren't slowing me down. Is that right? Does that mean my low fps is rendering related?

In a completely empty world, I get 60-80 FPS.

Solution 1:

TPS and FPS is not related. If you're getting a low FPS, but max TPS, it might be because you need a better graphics card.

TPS is how many times certain things in the game updates. By default, Minecraft updates 20 times per second. Each update is called a tick. "Ticks Per Second"

You can have more TPS than FPS, but the game will still be updating 20 times a second. Or, you can have more FPS than TPS, your screen will just show an image of the game that isn't updated from the last image (frame). Not everything in the game follows the TPS, that's why you don't get capped at 20 FPS.
