Quantum Break PC performance thread

30fps feeling poor on PC is the norm.
The best combo is setting 30fps in RTSS and set vsync to "1/2 refresh rate" in nvidia control panel.
The game seems to suffer from poor VRAM management.
Monitoring the VRAM usage, It started at something like 3GB and the game ran smooth, even during cutscenes/scripted events and a particular intensive scene (
) . After a while, it was close to 5.5GB and stayed there (980ti), even during the Tv show, and at this level it was when stutters started to happen, dropping to 4GB after a particular hard one.
How is garbage collection for GPU code?

How is garbage collection for GPU code?
I believe that's mostly handled by drivers for DX11 and earlier games.
Does that apply to folks with G-Sync monitors too?
Oh right, that's outside the range that G-Sync operates within. At least I think so.

gsync works at all ranges. when below 30 fps it uses some type of frame duplication technique. i dont remember the details
I found that when I turned Global Illumination down I was able to run at a pretty consistent 60fps with upscaling off + everything else near max.
That setting on max is a framerate killer.
Yep, that's the ticket to getting a "smooth" 33.3ms on PC. Feels pretty good with a pad.

Here's a hilariously dumb question: I'm assuming you need to pop in the first disc to activate the Steam copy? CE came in today and I realized that I, like, don't have a disc drive plugged into my desktop anymore :lol
Edit: ...I had lifted up a couple of the discs without seeing the code printed beneath the first one. I'll see myself out.

This is not such a dumb questions - some copies of Deus Ex Mankind Divided in eastern europe actually require to have the disc in the drive in order to generate steam key - I had to use my S/O's laptop for that, as my PC does not have a DVD drive.

Hows the streaming guys and how much data does streaming each episode takes abouts?
With upscalling on, sure.
What do you mean upscaling? I mean normal like any other game
It's an option in the game that trades a bit of visual quality for a large boost in performance. Not really the same as normal upscaling, but that's what the option is called.

A different but similar method to the way a lot of PS4 Pro games will do 4K. It takes a few lower res frames and reconstructs them into one larger frame. QB's version isn't as good as what the PS4 Pro does.
Well, that is weird. Why don't they just offer normal native resolution?

Because:
And they do offer normal native resolution, it's what you get with upscaling off.
Actually, PS4Pro doesn't "take a few low res images and reconstructs them into a larger one". Checkerboard rendering is happening in the actual 4K resolution but with empty quads which are filled later during the reconstruction pass. With PS4K there's no low resolution image from which it "upscales". It's also rather unlikely that they are using MSAA for edge details. It's a totally different solution basically.

.9 is close enough to 1. 4:8 is the same ratio as 1:2.

It's a different technique to do the same thing.
"4K" frames consisting of lower resolution frames blown up by adding blank pixels around each actual pixel and then filling them in is still taking low resolution frames and reconstructing them into larger ones. It's exactly what the PS4 Pro is doing. It's just doing it in a different (apparently better) way than QB... Which is exactly what I said.
It is literally a lower resolution image being upscaled through a reconstruction process.
He's incorrect as he is claiming that the PS4 Pro isn't creating higher resolution frames from lower resolution ones.
It is. It just adds a bunch of blank pixels around each one and the fills them in to create an approximate larger frame.
It's a different technique that has the same result. Which is what I said.
Also... You have the same ratio. You start with fewer frames, but you end with the same ratio of resulting frames.
As such... Setting QB to 4K with upscaling on results in the same ratio and pixel count.
The PS4 just uses an apparently better technique. (checkerboard)

There are no "lower resolution frames", with blank quads omitted you don't have a lower resolution image, you have a pixel soup which cannot be shown as is at all. The image's resolution is still 4K even with blank quads in it. And it doesn't reconstruct into a higher resolution image, from what we know so far it just combines two images temporarily with each next image omitting different quad grid from rendering. So it's temporal "upscaling" if you like, with some motion vectors taken into play most likely.
This is completely different to what QB is doing as QB is in fact rendering in lower resolution with MSAA 4x and using that final image with additional MSAA edge color information to upscale to a higher resolution image on the final rendering stage. I'm not sure that there even is a temporal component in that upscaling process, and QB's way of handling this is considerably more performance intensive - but it's likely to produce less artifacts in camera moving sequences.
I don't know how exactly QB's upscaling works, but here's how checkerboard rendering works in general:

They do... I said it's an option.
Turn off anti-aliasing as well. If that doesn't completely do it, use some sharpening as ^ that guy said.
The game might be using some kind of wide MSAA resolve(like the order), which would have this effect.

From your source, even Eurogamer says its extrapolating a larger frame from a lower res render...
Please see above. Even Eurogamer agrees with me.
Or well, here's the part. I don't actually expect you to look at it.
You are ignoring reality. The PS4 Pro doesn't render native 4K when this technique is used any more than QB is rendering natively with upscaling on. They are both using techniques to extrapolate higher resolution images from lower resolution rendering. That's reality, I really don't know what else to say.

That EG blurb is wrong, 2x2 into 4x4 is not checkerboarding and it doesn't make any sense pixel numbers wise considering specs.
Nostremitus
Member
Please show me where I said it was the same technique.
I said it was a different technique meant to do the same thing; make larger resolution frames from lower resolution renders.
Whatever dude.
It achieves more or less the same thing but does it using a different method - so it's different.
Plane and train are meant to "do the same thing" - transport you from place to place, but they do it in a completely different way.
Nostremitus

That's what I've been saying this whole time. You just paraphrased me.
That's exactly what my original comment was about.
dr_rus

Lol. 2x2 into 4x4 is 4 into 16, a 4x times expansion, basically a 1080p into 4K, something you'd do on OG PS4 to get 4K output, with abysmal quality most likely.
Nostremitus
Member
LOL, that's not why I said that. Now you are arguing a technicality that has no bearing on anything we've been discussing. What does it matter if it's 2x2 to 4x4, or 1x2 to 2x2, or any other arbitrary numbers? That doesn't change the technique, just the sizes. It is a different topic.
The reality is that the PS4 Pro turns a lower res render into a higher resolution render. It uses a different technique than Quantum Break, but they are meant to serve the same purpose.
dr_rus
Member
I'm arguing the quote from EG as something confirming your words, not technicalities. They are wrong as what they're describing is pretty much just regular upscaling you get when outputting from say PS4 to a 4K display. This isn't what PS4Pro is doing.
Nostremitus
Member
Either your reading comprehension is horrible and you honestly believe that's what they were saying, or you're just intentionally misrepresenting what I said and what Eurogamer said just so you can still refuse to admit you're wrong. Either way, I'm finished talking with you.

Does this happen all the time or is it a bug in some section?

Okay. Just remember that PS4Pro's checkerboarding does not involve any kind of low resolution rendering or upscaling, all frames are 4K there, with missing parts (unless a game is using a different approach obviously).
Wowfunhappy

I don't understand.
If some frames are missing pixels, doesn't that mean the frame isn't 4K?
Just think of a 4k image, with a checkerboard pattern of missing pixel quads.
