App Plugins Folder

Questions maybe only the Developers could answer..

Does app scan the system and adds only what is needed?
I've noticed the folder is missing dll's that some other games use.

Are we allowed to add our own dll's to the plugins folder?
I would like try running the game on an old machine. An example of dll's I would add to the folder to try on an old system:

d3dscache.dll - Microsoft (R) D3D Shader Caching Library
qd3d.dll - QuickDraw 3D
dsound3d.dll - DirectSound3D LUT
d3dim.dll - Microsoft Direct3D
d3d11on12.dll - Direct3D 11On12 Runtime
d3drm.dll - Direct3D Retained Mode DLL

Hi there,

Not all games use the same DLL's and the ones you listed usually come along in windows distros nowadays.

Not sure if adding these DLL's would even make a difference either as they are not referenced by the code as far as I know unless  it looks for them in the windows folder which it might.

The minimum requirements are as follows:-
Operating system
Windows 7 SP1+
macOS 10.12+

CPU
SSE2 instruction set support.

GPU
Graphics card with DX10 (shader model 4.0) capabilities.

32-Bit or 64-Bit only?

The normal game before 3D was added worked no problem on 32-Bit system with only 3GB RAM

Well that answers that question 64-Bit only So I will copy the files onto USB and change a few things to 32-Bit and pray it doesn't crash on start up. I maybe some time. Need to look at all files to see what ones are 64-bits even ones you think people can't open hehe

I tried and I failed 
Rebuilt the app in unity as 32-bit
It looks the the part
It feels the part
It just doesn't do the part.
