Not all the time no, only when you rush and disregard making a good port does that happen and that isn't all the time.

Hmmmm you say you dont care about metacritic but yet post on this thread on even complain about its average review score and insinuate that the score may even be rigged somehow

But you fail to notice/say that:

Quantum Break has 86 scored critic reviews and:

• 49 of those score 80 or below (57%)
• The vast majority of those reviews score 78 or below (60% of the 57%)
• The handfull of high/good reviews are too small budge the score (Only 24% of reviews)

Most are positive. You need to also realize that just because it didn't score a 90, doesn't mean its a bad game. Most games have far lower scores than they did last gen (since they were overinflated at the time). 

Probably MS intentions with UWP clashed with the differences between Windows for PC and other Windows systems, so the tools cannot do all in a quick and almost automatic way, but careful adaptation, tweaking and optimization are still needed and rushed ports will still work poorly. Maybe in the future tools will make things easier or maybe there are intrinsicly non bypassable obstacles and some manual work will always be needed to port games and other SW between different versions of Windows inside this dreamt unified world.

Tools will never be able to do all the work

On Xbox One, Quantum Break uses a clever reconstruction technique designed to free up resources while producing a relatively clean image. It works quite well. On PC, with more capable hardware, we would prefer to see an option to render at the native resolution of our display without this feature - but this is not provided. What this means for users is that '1080p' effectively produces a reconstructed 720p image rather than a native full HD output. Rainbow Six Siege offers a similar technique but on PC, it's optional. This is a technique that looks nice on a television from a normal viewing distance, but when you're pressed up against a high resolution PC monitor, the results are blurry and lacking detail.

They tried a straight port and it's a mess. The current render engine simply isn't suited for PC.

"Ugh" is all I can say.
Not a fan of Microsoft's new foray of trying to control the PC gaming ecosystem again.

That entire article painted a very ugly picture.  Seriously, if they expect to cut into the PC gaming market, they have to do better than this.  I don't want to support UWP, anyway, and they're making it easy for me.

The real kicker is that these performance problems are only exasperated by the basic limitations the UWP format still possesses, and will continue to possess until Microsoft's promised improvements come forth. When discussing the poor frame pacing and performance, I've seen mentioned a few times something along the lines of 'Well, NORMALLY you could use so-and-so outside program to fix this problem and/or improve performance... buuuut currently UWP doesn't let you do that, sooooo... bummer!'

So, basically not only is the game itself a very poor port job... but it also lacks even the inherent flexibility that would normally let the community troubleshoot and fix at least some of those issues themselves. At this point, it looks like improving the game's performance is solely going to come down to Remedy and Microsoft.

And I figure they will be working on overdrive to try and patch things... well, mostly I do. Most of me thinks that there's no way Microsoft is going to Warner Brothers this up, and leave their shoddy port ultimately unfixed so they can focus on the 'Next Big Thing,' but on the flip side... well, the flip side is I never thought they'd be foolish enough to let so poor a port out the door in the first place. -_- At least with Arkham Knight there was this underlying sense that Warner Bros just didn't feel super invested in the PC platform, as a simple game publisher. But Microsoft has EVERY REASON to care about the Quantum Break port; it was supposed to redeem the UWP platform after rumblings about the PC port for Gears of War, show that PC gaming on Microsoft's chosen storefront was indeed shiny and viable.

Whyyyyy did they screw this up?

Has there been ANY word from Microsoft or Remedy about this? I haven't seen any, yet anyway, but I may have missed it.

Definitely not a fan either, in fact it's caused me to take a step back and consider sticking with 7 until devs stop making games for the OS and then I'll be hopping onto Steam OS and possibly even 8, 10 is just an OS with a closed system that is going down a path I simply don't want to follow, I like PC gaming for being an open platform, not a closed restricted one.
