Looks like mine won't arrive till next Monday or Tuesday. Shipped from Ontario CA. Wonder how quickly it would have arrived if I had used my Los Angeles address?
You should be good to play any of those. Last year in Oct/Nov I spent a lot of time playing with my niece/newphew's Decks. Doom Eternal was one of the games I spent a couple hours playing. I had previously played Doom (2016) on my desktop PC and was very familiar with how it felt in action on higher difficulties. By comparison, the Deck ran flawlessly (and if memory serves, I was playing at a stable 60 fps or close). Personally, there are some games I'd just rather play on my big screen to soak in all the glorious visuals, but it was still quite impressive.
More surprising was when my nephew used his Deck to boot up the Wii U version of Zelda BotW. I don't recall if it was 60 fps, but I was able to play it at a mostly stable frame rate far exceeding the Switch. They have 5 Nintedo Switch consoles in their house, yet the best Zelda experience is on a Deck lol. Nintendo's Switch 2 can't arrive soon enough; BotW is almost 7 years old..
Something else of note, the kids have a 512GB and 256 version. This was great because I could test out the same games to compare the etched glass screen. Both screens were perfectly acceptable, but if I was in a brightly lit room, of course I'd prefer the etched screen. Otherwise, I think I'd rather have the standard glass. It looked more crisp with better pop to the colors, but downside was the sharper image made pixels and jagged edges more discernible. The etched glass muted the color saturation, but it also acted like a form of built-in anti-aliasing and smoothed out the jagged edges. Next time I get a chance, it'll be fun to compare my Switch and Deck OLEDs versus the LCD variants of both.
