One of my machines is running on a 2011 CPU and it still run everything great unless I enable raytraced rendering which can only be used on my newest PC… But it’s not running Linux, Epic isn’t known for being a Linux supporter, Unity also took ages to make a Linux editor.
Anyway, buying a proper workstation is very cheap when compared to developing video games, using a problematic setup and blaming the software is only adding to waste of time/money/energy.
If you have money to develop a video game then you must have money to buy a non domestic computer.
