That's definitely frustrating, Rolling back drivers is definitely one of the most prescribed fixes for DirectX issues, and since you already did that, it's promising that it's probably a software related issues and not a physical hardware issue (especially if there aren't any graphical artifacts). A couple of things you could try.
- I always like to toggle windows game mode off and see if helps
- I think you mentioned updates, but sometimes you can try going into windows store and looking at downloads and updates, there can be random extension helpers and such that might need updating
- just double check Armoury crate is all updated.
- Do you use HW monitor at all, if so how are temps, you can always look at AC, but HWmonitor is a little more indepth, and it also shows you PCI errors in the GPU section. (though fair warning windows and most hardware have some errors, so it's most likely you see atleast some errors in HW) If you see a huge amount of errors for ever type and their rapidly climbing, perhaps some of the next mentioned steps could be helpful.
- If you've heard of DDU at all, you could always try to a full uninstall and reinstall, although it can be a little finnicky and bit of process (there a many web based and you tube tutorials on it though..) If you rollback are you using NVidia's clean install as well>
- Finally you could just do another install of windows, it kinds of side steps doing anything else, also as a note when you're going through drives for reinstall I typically just delete everything ( except of course the USB drive where to reinstall is). Avoid installing any GPU drivers first, get windows updates all done, you can do chipset, bluetooth, i/o, etc. just wait to do gpu until windows ahs finished administering updates. After you all fresh and ready to go, just go grab NVidias drive from their website and do a nice fresh clean installation under custom install. This option is the most nuclear, but it usually solves my issues if I think it's a software problem I just can't get to behave.
Best of luck, hopefully you don't have to go all the way in deleting, but if so, it is usually pretty helpful. Let me know how it goes and good luck,
