Why doesn't Minecraft use all the graphics power?

As already described in the title, Minecraft does not use my whole graphics card.

You can tell from my FPS. The card is only 30% full although I would like to use the graphics card 100% that I have the most FPS. Why is that?

Because a horse only jumps as high as it has to.

Where can you change the "must"?

This is because a computer is only as fast as the weakest link.
The graphics performance is all well and good. But your CPU is probably whistling from the last hole or the ram is full.

The ram is 50% busy and the CPU only 60%

Minecraft is less GPU-heavy, the CPU uses it much more. If you want more FPS, you can increase the processor priority for Minecraft. Instructions are available on the Internet and are very simple.

You can also assign more RAM to Minecraft in the launcher under installations. You should reserve half of the RAM you have for Minecraft. This is also very easy and can be found on the Internet.

And how much FPS do you have?

Minecraft requires very little graphics power (except for shaders). Pay attention to the CPU usage. It is usually very high.

55 xD

If the CPU cores for the 1-2 main threads of this game are already 100% full and therefore limit, then even the fastest graphics card is of no use. The CPU brakes and the GPU starves to death on the long arm due to insufficient feeding with render data.

Since you named a combination of Radeon R5 Series + Radeon 330m in your other question, an old and weak AMD A-Series "APU" will probably be installed in your notebook, which will reward Minecraft with correspondingly low performance.

Enough.
I mean this is Minecraft and not an FPS…
Are you wearing VSync?

No

Then see if you can do anything with Meatgrinder's answer.

Can you send me a link
