Minecraft lies extremely without Vsync?

I only have a 60Hz monitor, which is why I usually play with Vsync, otherwise I get extreme screen tearing. However, I can't play Minecraft with Vsync, otherwise I have a strong input lag. Without Vsync I get 800 FPS every now and then it drops down to 200 FPS. This leads to strong lags because the FPS go up and down all the time.

Hardware:

Processor (CPU): AMD Ryzen 5 1600 6x 3.20GHz So.AM4 BOX
RAM: 8GB (2x 4096MB) Crucial Ballistix Sport LT gray DDR4-2400 DIMM CL16-16-16 Dual Kit
Mainboard: MSI X370 GAMING PRO CARBON AMD X370 So.AM4 Dual Channel DDR4 ATX Retail
Power supply: 500 watts be quiet! Pure Power 10 CM Modular 80+ Silver
Housing: be quiet! Silent Base 600
Graphics card: VGA 8GB Asus GeForce GTX 1070 Ti ROG Strix Advanced
HDD / SSD: 250GB Samsung 860 Evo 2.5 SSD, 1000GB WD Blue WD10EZEX HDD.

You can limit ingame in the settings to 60 fps then they don't always go up and down or stop at 100 as you want

Download the "Rivatuner statistics server", you can then cap your frames and you shouldn't have any more lags!

I think it's time for a new monitor

But then the lags have nothing to do with the monitor, do they? Screentearing in any case, yes.
