I don't have a program that tells me how much fps my computer can hold. Btw here's some info about my pc: 64-bit Gnome 3.26.1 Processor: Intel® Pentium(R) CPU G3250 @ 3.20GHz × 2 Graphic: Intel® Haswell Desktop 8GB
i got a program called CCSM (Compiz Configuration Settings Manager) and I turned off Vsync there, but still, i can't see a change on the fps in minecraft.
