The game does not recognize my graphics card.

Causticsims​  The unrecognized graphics card has nothing to do with whether your custom content works.  And you should only see the unrecognized GPU error one time, or once again if you delete the Optinos.ini file, which stores the flag that you've seen the error already.

I'll move you to the Mods forum for further help.

Causticsims​ It's no CC at all? Or your whole folder? Please start by trying this:

1. Drag your whole Sims 4 folder from Document > Electronic Arts to your desktop and rename it.
2. Run a Game Repair in the EA App. (If you use Steam, the equivalent is Verify Integrity.)
3. Launch Sims 4. You should get no list of mods on launch, and you should have no option to load a previous save. Reset your Options.
4. Exit and download a new piece of CC to test with. I usually use a recent peacemaker furniture item, as there are definitely no issues with them.
5. Install it in the newly created Mods folder, which will have only Resource.cfg in it.
6. Now try launching a new save.

It's no cc AT ALL. I've cleared the cache, I've repaired the game, I've uninstalled and reinstalled the game, I've reinstalled the ea app. I've 50/50 my cc and nothing's working, and the weird part is it's ANY cc. It will run UI Cheats and MCCC just fine, but any piece of cc and I get the error "something has gone wrong on our end please wait,"

I'm a veteran player, and I've never encountered something like this before. 

(Also thanks for being a hero on update days!)

Thanks, it's appreciated!

And to confirm, you did the exact steps I noted there? Please also make sure your antivirus and firewall are exempting the Sims 4 folder (see https://answers.ea.com/t5/Technical-Issues-PC/CURRENT-ISSUE-Anti-Virus-blocking-User-Folder-Screenshots/td-p/9572695 )

Yup, I did everything above. Just tried the firewall fix and it didn't make a difference.
