In 1.12.2 there is no effect, does it mean that it is not supported in older versions?

It should work. Could you share the command you're using to launch it?

java -Xmx8G -Xms512M -Xss512K -javaagent:./ignite-launcher.jar -Dignite.paper.minecraft=1.12.2 -Dignite.paper.target=io.papermc.paperclip.Paperclip -Dignite.service=legacy_paper -jar ignite-launcher.jar ignite.paper.override=false paper.jar

The additional flags will no longer be needed in the new version of the game, other than the javaagent. Make sure to follow the new readme for Ignite 1.0.0-SNAPSHOT (you will need to build this yourself until it is released).

The latest release should help by not requiring the flags. Feel free to join the Discord for help if you're still confused.
