Upgrading to gig internet breaks series x and s network performance

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.

I wouldn't consider anything that does not offer 4k @ 60fps (Or 4k ((Upscaled) @ 120fps) to even be next/current-gen. We've been living in a 30fps world for far too long. Upgrades we're promised and while many games aren't optimized perfectly (and, lets be honest "Series X/S Optimized" really just means "we upgraded it for the Series X capabilities and just assumed it would be fine on the Series S") better performance should be expected.

To be clear, did you buy a One S or a Series S? Does it have a disc drive?

You shouldn’t get any upgrade prompts on a One S, X/S games will not run on a One S, if you upgraded the game to the X/S version, so if you have One S, you should decline upgrades

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.

Kyle you did send to me the information on the info about Series S and Series X but you did not provide to me the clear answer what are better between Series S and Series X on the performance and gaming?
