Will there be a X box Series X Pro with upgraded Hardware and performance?

it was made clear in 2020 that they were launching the generation refresh with the Xbox series X

While there may be hardware revisions coming around, it would likely not entail additional computing power

Not really...

Xbox Series X games / upgrades / updates has to be installed onto the Series X internal or expansion card SSD,

You can have Xbox One games on your external hard drive that will get an Series X upgrade but the games will need to be transferred to the Series X and then the Series X upgrade will need to be downloaded onto the Series X SSD,

As an example...

I have Marvel Avengers on my external hard drive that will get the Series X upgrade and I will transfer the game over to the Series X SSD ready to download and update the game to the Series X version when available.

Pretty sure they're not using Vulkan on Xbox.

How they run depends on what console you're using. On Series X they're excellent, and Doom Eternal even has raytraced reflections on the Series X hardware. The RT can drop the FPS to just below 60 occasionally, but it's largely flawless.

On the now older Xbox One S their resolution is limited to around 900P, but they run much smoother and in higher res on the One X and Series X.

If you've got a Series X, Doom 2016, Doom Eternal, Wolfenstein II The New Colossus and Wolfenstein Youngblood play really well. No major performance issues. Digital Foundry on YouTube have conducted extensive tests on these games. I would check them out.

Doom Eternal Next-Gen Upgrade: PS5 vs Xbox Series X/ Series S - All Modes Tested

Dying Light 2 is a big game and highly anticipated. Series S owners are paying a next-gen price for the game and will wonder why they're only getting a last gen 30 fps performance.

Remember, you're not stuck with the Series S version. When availability gets better you can always exchange your S for an X. When you upgrade, you'll get access to all the Series X features for this and other games.

I upgraded my Series S for an X.

My issue is the same. My additional input: I just bought the X-Box Series X 2 weeks ago. I transferred all my games over. At first, every game I tried worked fine. Then the system suddenly decided yesterday to upgrade the newer games to the Series X versions of the games. Every game that is older and doesn't have a Series X upgrade works perfectly. It's only the games that have upgraded to Series X versions of the games that have "no audio" issues.

For reference, I do have a Samsung smart TV as well, a I've been reading other with this issue may also have. I have audio on the dashboard.

Hoping for a fix soon. Thanks.
