The oldest computer that I have tried running this engine is a HP laptop from 2008, running a 32-bit version of Windows XP.
It seemed to work fine, but I did have some issues with the Direct3D 9 renderer. The renderer works fine on other computers, so I have no idea if it's a driver bug (Intel tends to have buggy drivers) or if it's a bug on my part.
The biggest problem with using old hardware is drivers. Older drivers will only work on older operating systems and it's difficult to find C++20 compilers that will work on them.
