Hi guys, I bought my tablet purely to draw on Clip Studio Paint and stream the process; it did this beautifully under Win8.0, but ever since the Win8.1 update, the processor and/or RAM usage between Clip Studio Paint and Google Hangouts/XStream has shot up so much that everything screws up: my tablet driver stops reading pressure properly; my undo combines the last two seconds of actions into one (rather than being per-stroke); I keep getting erroneous palm input; the Samsung Touch Helper ceases to work entirely; and I honestly don't gain anything except for a slightly better on-screen keyboard. I run all the latest Samsung, Microsoft, Wacom, and Clip Studio Paint updates. I've had enough: if the issue hasn't been resolved in over two years of patches, it will never be resolved. I want to return to Win8.0. However, my tablet (model is in my signature) came from the factory with Win8.0 (quite possibly a Samsungised version of Win8.0). No disc involved, and the software key is unknown to me as it was all pre-setup. Is there any safe way I can downgrade to Win8.0? I talked to a Samsung service rep in England who said that if I reset Windows, the system would return to being a fresh copy of Win8.1, and that Samsung don't keep obsolete versions of the tablet system to reflash specifically to Win8.0. Any knowledge on this? Was he right?
