I was playing the Witcher 3 on both my 1TB OLED and LE decks while waiting for valve support to get back to me. The menus definitely show that problematic grey. The green tint and graininess was really apparent on the standard deck. On the LE the greys are very uniform and smooth. There’s some slight banding but it looks a lot better than the Samsung display.
The standard deck is being returned to valve and my LE will be getting replaced for dead pixels. Hopefully the uniformity on my replacement LE is just as good or else I’ll regret sending it in. It would be nice if ifixit offers both the Samsung and BOE panels
I had a hard time maintaining anything over 30. The game feels great at 30 in a 90hz container on the OLED though. I used xess quality for upscaling and a mix of settings to get it dialed in. There is a lot of issues with the game like falling through the map and input not working on startup but when it does work it is a ton of fun to play on the deck.
