It's doubtful that the mod will do anything for you. You can, if you want to, download the mod from the mod thread and extract it to the game folder. All you need to do afterwards is to launch the game, wait for the main menu to finish loading, then hit Ctrl+Shift+Backspace to open the control panel of Special K and click the "Logical cores" option listed in the Monster Hunter World section, if it isn't selected already. Then just restart the game.

If you notice any improvement, then that's great! If you don't, then that's basically expected.

Your computer, sadly, in general is quite a bit too underpowered to run Monster Hunter World properly, so the best bet for improving performance that you have is decreasing the graphical settings of the game and resolution through the in-game settings.

When I re-opened MHW. The game I wouldn't start. All I get is a black screen.

Probably third-party conflict of some kind. Remove the mod by deleting the dxgi.dll file from the game folder again.

Should I re-paste the dxgi.dll file again. Can I use the Special K without the dll?

I honestly don’t think it will do much for you, but if you want to, please uploads the logs from the logs subfolder to pastebin.com and link them here, so I can take a look at them.

If you use Nvdia Shadow Play, the game won't start while you have Special K
