Fallout 4 CTD on startup

Hi,

I've been trying to add ENB + ReShade to Fallout 4, but the game black screens and crashes to desktop on launch. I've tried different ways and versions having looked at a bunch of different posts about the same problem - most say a common problem is an overlay or background app but I don't believe I have any of these, and ending pretty much every background process in task manager didn't work.

I've tried the latest installer version and a manual install of framework 1.1.0f1 (including renaming ReShade64.dll to dxgi.dll), both on a fresh install.

Please let me know if you can help or if you need me to post logs etc! Thanks!

It appears this only started since the most recent patch.

Renaming it to d3d11.dll works.

Unfortunately there is a very useful load accelerator mod which uses a custom d3d11 as well. It will crash as dxgi.dll with or without it.

Used to work fine.

Wait, it's just because of 'optimus' mode.
