@Dungeony-Splatty Any mods from NRaas are fine, but please remove other mods and any custom content you use.
If that doesn't help, did you make any other changes, for example adding the Smooth Patch or editing the .sgr files or installing ReShade? If so, please remove the added files and repair the game, then test again. It doesn't matter if your graphics card is unrecognized, although if you want to fix that (again, or for the first time), I can help with the process.
Now that I write that, I have seen one or two players say that getting their GPU recognized fixed some performance issues. That shouldn't be the case, but still, if you'd like to try and want my help, let me know. If you want to try and don't need my help, please don't make any other changes, to the .sgr files or in general, after repairing.
