Gears of War 4 will perform better on the Xbox One S than it does on the Xbox One that released in 2013.

While Microsoft was quick to tout 4K video support and upscaling for the new version of the Xbox One announced at this year's E3 and available in August, the company also announced support for high dynamic range color on the console. While that in and of itself will provide subtle visual improvements to Gears of War 4 — The Coalition studio head Rod Fergusson talks in particular about improved surface detail on things like metal and armor — it will also provide a more consistent level of technical performance as well, Fergusson told Polygon in an interview following Microsoft's press briefing today.

Gears of War 4 employs a dynamic resolution system that tweaks the game's rendering resolution in both single-player and multiplayer to maintain its target frame rate in each mode (30 frames per second and 60 fps, respectively). According to Fergusson, the Xbox One S has additional raw GPU and CPU power compared to the Xbox One, and The Coalition's engineers have been able to take advantage of that to reduce the frequency of frame rate or resolution penalties in more demanding sections of the game.

While Gears 4 will take immediate advantage of the Xbox One S, that change does not automatically ensure a native 4K version of the game is ready for the newly announced Project Scorpio, Microsoft's 6 teraflop console upgrade currently slated for release in holiday 2017.

"We have to look at what the engine can do with the power that Scorpio has," said Fergusson. "Because we're mastering at 4K, it's not about assets or art. It's about getting the milliseconds down in terms of getting the game to 4K at 60 or 30 [fps] depending on single-player or multiplayer."

The Xbox One S will debut in August.Gears of War 4 will launch with Xbox One S specific support on Oct. 11, 2016.

UPDATE:

Microsoft has confirmed the "additional processing power" in a statement to The Verge. "We have the same SOC architecture as Xbox One today," explains a Microsoft spokesperson. "For games that want to take advantage of HDR, we gave developers access to a small amount of additional processing power." The additional processing power won't be significant, and it appears it's limited to HDR titles. Microsoft isn't detailing exactly what chipsets have changed inside the new Xbox One S, but it's reasonable to assume that the Xbox One AMD APU chip has been downsized somewhat for the smaller console, which will help with processing power and thermal thresholds.

Along with the IR blaster, this might push me to get an XboneS. It would probably rid of the laggy as fuck UI, which ruins my TV watching experience.

What is so bad about a Slim version that runs games a bit better, it's not very unusual either I believe. It's something different when the graphics card is over three times as strong as rumoured for the scorpio and Neo

Has Microsoft said anything about the ram in the Xbox S? Did they upgrade it from DDR 3 with ES to better ram?
The ram setup currently used is blamed for it's less than stellar performance compared to the PS4.

How much does it cost in european currency ??
Im tempted to buy one

Will most likely buy on release date, my sister will buy my old X1 anyways :).

Switch the dollar sign to a euro one and that will probably be your price. Unless you use pounds or some other currency.

Then its 299 euros 

Great price 

the games are programmed to use that ram setup, so I don't know if/how it would work with a different setup without pretty much every game needing a patch

Does it really matter? I would think it doesn't. Maybe I'm just not familiar enough with low-level development, but I haven't run into anything that would suggest adding RAM would make things worse, as long as the specs stay the same. Anyone with deeper understanding of low-level programming willing to correct me?
