Radeon GPUs with ATI driver not utilised

The first cards' vram is half-full and both the cards sit under 10% usage, I don't know if it is because of wrong hybrid configurations or maybe because of something wrong with Xorg.
When I launch games (only tried with minecraft at this point, just plain old vanilla) GPU usage does not pass 2% and CPU doesn't go lower than 95% after like 2 minutes the cpu overheats and shutsdown.
I can send any other log if needed.

What exactly are you expecting to happen/is your end goal? You can forget "direct sharing a la SLI/Crossfire, load balancing" (do you have a crossfire link cable? Again this isn't going to work anyway, but if you don't then any slight hope you might have had isn't there to begin with) pretty much outright. What you can do is offload applications to one or the other card by starting them with DRI_PRIME=1, which does have a very slight chance of helping if you are really pushing the GPU, but doing offload from a same level graphics is likely to just be slower, with no benefit. But this just reads like not a very good card to begin with so you can't and shouldn't expect any wonders.

If you want to check why minecraft crashes (which is a pretty demanding game anf might crash due to missing RAM) look at/post your journal, monitor RAM usage, and possibly run the game in a terminal to get output.

I have crossfire link cables connecting the cards together, I have 12 Gigs of ram and I don't think that's the issue, I will post the journal in a minute

There is a problem with java right now that I am too lazy to fix so I can't post a journal.

The weird thing is it doesn't use the gpu even when I take out one of them.

RV790 is pretty dated and might not meet the feature demands on virtual LEGO, resulting in sw emulation.
Or you're lacking some GL libs, "glxinfo -B; glxinfo32 -B"

I took one of the gpus out, there is just one of them running now

Inofficially (source: google; I couldn't find a reference on their ADHS webpage…) minecraft => 1.18 requires OpenGL 3.2 (that's not the core profile) and won't run on your GPU.
You'd have to check the minecraft renderer info/console output/logs to be sure, though.
