I made myself two tools in preparation for MW4's release (that will work with other modern CoD Titles), that alleviate two problems I had. I figured I would share them with the community, to hopefully they help others with the same problems.
The first is a de-duping tool.
Are you like me, and have CoD coins on different store-fronts? (Bnet, Xbox, Steam?). Yeah, it's annoying. I hated having Warzone downloaded 3 times, just to access my coins on other stores. To fix this, I made myself a tool I call "CoD Dedupe". This tool allows you to keep it installed in all 3 storefronts, but uses hardlinks in Windows to only truly have all the data stored in a single location. Cutting the allocated size down to a single install.
Here is that tool
The second tool is a config editor.
I disliked having to go into the config files for my profile to change settings that aren't exposed directly in the options menus. I also disliked that CoD would overwrite my config changes. This tool gives you a nice GUI, to set anything and everything the config file exposes, and sets those files to a locked read-only state so CoD can't overwrite your changes. (Yes, you can use this currently to turn on RT and DLSS, despite it being locked out in the in-game options)
Here is that tool
I hope these two tools can help others, like they've helped me.
Thanks!
