Heres a small detailed information section for you.
I have updated Java to the latest, as of what is avaliable on 1/12/2018 (No change.)
I have updated my graphics drivers, to of what is avaliable on 1/12/2018. (No change.)
I have increased my RAM, in-game and on my computer. (2gb, 4gb and 6gb have all lead to the same crash.)
I have tried disabling the splash screen. (It leads to a blackscreen, but the same crash.)
I have looked at answers, forum-posts etc for the past month, tried many of their fixes to see if they would work (Even if they may not, never hurts to try.)
I have done other things, but they can't come to mind right this moment. Here is my fml-client-latest
Here is also a gyazo link to a picture of what happens to the launcher. It stops responding at this point, nothing I can do. I left it on for hours to no avail.
Also, I am aware that the picture shows 1024mb allocated. Be assured, even at 4gb, 6gb, it does the same thing.
