Minecraft runs with me on the max settings only with 40 fps. I dare to doubt that the performance of my PC is the reason for this. When I was playing yesterday, I had 500-600 Fps with the same settings for a reason I can't explain (that was never like that before, and did not happen again afterwards). How can I increase the Fps again without the settings down? Put?
My PC:
AMD Ryzen 5 3600 OC 4.2Ghz
Zotac GTX 1080, 1900Mhz
16Gb 3000Mhz DDr4
Take a look at the utilization of the components.
What else is going on in the background?
Cpu = 15%, Gpu = 20%
I would see that minecraft gets enough memory allocated.
That does not help: in Windows, see if the pc is set to maximum performance.
Vlt. Minecraft runs only on a core.
If everything does not help reinstall the game.
Then you know that your components are not delivering full performance.
Did you maybe activate vSync or FPS limitation?
