I have a pc with a gtx 760 and i have only 60 fps in minecraft although according to the internet i would have about 300
What do you have for other components in the PC? (Eg graphics card RAM, etc.)
Press ESC and go into the options and there in the video settings. It could be that there the FPS are limited to 60.
A gtx 760 with gigabyte 2gb a ryzen 3 2200g 16 gb ddr4 2400 and an intenso ssd
PS of the pc has finished only one hour ago
And what should you bring 300 FPS in contrast to 60FPS? If you have no 144Hz monitor or 240Hz then bring you synonymous 300 FPS nothing. I assume that you have a 60Hz monitor if you already have such an old graphics card. And 60Hz monitors can't represent more than about 60 FPS anyway.
Because of shaders
Have nen 144hz monitor from asus
