Why does my colleague have more fps?

It is true that my colleague and I have the same pc

mainboard b450 pro

Ryzen 52600 processor

ran 16 gb

except graka

i have an rx570 with 8gb

and my colleague a gtx770 ka how much gb

and he has 300-500 fps on the same settings in minecraft and I 100-300 which I don't understand because my graphics card is actually better or Fortnite he has more on the same settings

Maybe you have more applications running in the background.

The programs installed on the computer also play a role, the connected monitor, possibly viruses, dust can also impair performance

Graphics card driver current? What is the rhythm of the two of you? What are the temperatures and loads of your components? All of this has to be checked to find an answer.

With such high refresh rates (beyond 200 FPS), you can often no longer understand what leads to the differences. This can be the driver, it may be that your card design has a shader pipe less than that of your buddy, which doesn't matter otherwise, it can be anything. In the end it doesn't really matter.

Does your friend use another client or a mod for more FPS?

No

Can be but where I had reinstalled the graphics card when I bought it. In December the game ran at 400 fps
