I recently updated my ACT ToolKit Help Document, with re writes and additional text. It is much easier to read and I've improved the understanding better for Windows 8.1/10 use.
After that I did some tests with it to see if performance can be increased in Windows 10 in D3D mode for EAW. (natively, straight with no wrapper program).
I have found some Fixes that work to increase speed, but just a bit. ;)
This Help Document explains the Microsoft ACT Toolkit and some usage instructions plus my on going testing results.
If you like working with the Registry or want to work with Compatibility Toolkit program by testing different settings , This doc is for you! :)
Here' s the page from my web site: https://eaw.neocities.org/windows-act-toolkit.html
It can get complicated, but if you have questions, please ask them here, and I'll try to answer them. Thanks!
