Possibly way to significantly decrease UI crashes and RAM usage: 2.6GB -> 1GB

So I find out how to reproduce it on Windows and posted a bit more user friendly how-to there:
https://forums.uberent.com/threads/how-to-decreasing-ui-memory-usage-on-windows-linux.63043/

Also I find out that Windows version of Coherent don't have "--single-process" working, but renderers limit is still there.

Using –single-process causes nothing to work for me, coherent crashes immediately when starting a game or galactic war. How do I use the patches that were posted? I’m an arch user and PA is still unplayable for me.

Will do so later, just played with an older build I still had on my PC which didn't run into this bug as often.

Edit: Didn't help
Is it still possible to download build 69721?
