240fps

Ram:8G CPU i5-4696 GTX 960 Minecraft 240 render I will record minecraft I'd appreciate it if you could tell me which setting is right for me All the settings I've tried are very lag. :(

Hi, so I'm a Fortnite youtuber. I record in 240fos (usually) and render in 60 to give it a nice smooth effect. Everything used to be smooth and fine, but now, it's always laggy, even when I record in 30 or 60 fps. I do get 240fps in Fortnite, so I don't know the problem. I7 6700k, a GTX 1060...
