I don't lag :)

Can you try again, but with MC version, BlockShot version, maybe an idea of what mods you have, how much memory you're actually using from f3, as it'll need a bunch of space ram.

This basically works by turning your frame buffer into a byte array, then sending it off into another thread, there is very little optimisations left to do...

Been able to find a more memory efficient way to encode the gifs, seems the library I used originally was not cleaning up after it's self so was eating huge amounts of memory.

Try version 1.2.5
