Hit, save. And restart the launcher. Now your game should start in 1920*1080 every time it loads the pack you play. (I also changed it in the Minecraft.settings, file. But doing it in json file only should be enough.
If it does not, you may need in the Twitch launcher to just once, change the resolution to what you want here too. BUUUT usually above solves the issue 🙂
That means that 1 tick happens every 0.05 seconds.
Above info is used a lot when making recipes with CraftTweaker. As many machines needs to know how many ticks a machine should run for with x amount of power. Like for some GregTech machines you need to use: .duration(40) .EUt(120) Which then means that the machine will run for 40 ticks which is 2 seconds, and every tick it will use 120 EU, which is a total of 4800 EU.
