Digital Foundry: Final Fantasy 15: PS4 Pro Gameplay - First Look/Tech Analysis

Can anyone explain in detail what frame pacing issues are? I'd like to know more for what I'm looking for.

Stuttering due to the frames not being put out in the right sequence.

Feels similar to when the framerate is actually dropping.
Although in this case it isn't

Its putting out a constant 30 frames... in the wrong order.

OK, think about it like this...

On a 60hz display, each frame will appear on screen for 33ms, right?

When 30fps is displayed properly, each frame will appear for exactly the same length of time as the previous and next frames. With bad frame pacing, you wind up with situations where two frames in a row will only appear on screen for 16.7ms while the frames following it will appear for 50ms. This variation in persistence gives the impression that the frame-rate is unstable and juddery.

It's all about the length of time each frame appears on screen.

Hey hey

In theory, at a higher framerate, frame pacing issues become less and less noticeable right? What would the cut-off point be?

It's basically a lower quality mode (same as stock PS4) and, in this case, it looks smoother in motion due to fewer frame pacing issues.

Thanks for this!

I can't wait for 4k HDR OLED screens to hit proper mass market prices. Once I can buy one for £500 then I'll bite. Until then I'm happy with 1080p and super sampling.

Or, in this case, 1080p 60??? *crosses fingers*

It's possible that they simply aren't engaging with the community? Between forums, Twitter, and the various people doing tech analysis stuff, Western devs will often read about these problems and investigate.

I know for certain that, in a couple of cases, we contributed to getting it fixed.

I could see some of these companies being fairly closed off from the community (including the Japanese community) so perhaps they just aren't listening? I wish I knew.

You would think that even if they aren't paying attention to the English community, the wouldn't ignore the Japanese one, surely?

Does anyone know if From Software ever even acknowledged the issue in BB or DS3?

See two guys : A and B. Both are walking 60 meters in 60 seconds.
A walks one meter in one second. His movement is smooth, no problem here.
But B walks one meter in one second, then one meter in 0.5 seconds, then another mether in 1.5 seconds etc.

In the end, both achieved the same distance in the same time (that's why both FFXV versions are 30fps) but while A moved in a smooth way, the B movement was jaggy, irregular, and overall absolutely not smooth at all.

B is suffering from frame pacing issues. Frames aren't timed correctly, causing the same feeling as when framerate drops but it actually doesn't.

Thanks for the explanation. :D
 
Thanks for this. This video really highlights some of the differences between HQ and LQ settings (well aside from frame pacing). Differences in shadow quality seem pretty evident as well as IQ.

I am so glad I decided to support these guys on Patreon. The uncompressed footage is absolutely amazing. I use a 55 inch KS8000 as my monitor, and this game looks so close to 4K native, it's incredible.

I got a question, pretty please.

When I am playing with rivatuner, sometimes I see games that keep 60 fps, and the frametime is almost 16.6 ms, but there is some variation on a small range on arround that number, only decimals usually.

I don't see anything wrong while playing. Is that normal? Is it imperceptible? Is rivatuner not perfect?

Apart from a few scenes here and there (while driving the LOD is clearly better in the HQ mode) I thought the Light Mode looked better o_O
 
Hopefully it gets fixed but Bloodborne and the Souls games didn't become unplayable because of a bit of judder, so I'm not really worried about it.

That frame pacing is absolutely awful.

I keep hearing about this, and how it was a problem in Bloodborne and Dark Souls 3 and stuff, but I have literally never noticed it. I get what it is, and I've grown more susceptible to frame dips and stuff as I've gotten older, but I've never once noticed frame-pacing being jerky or anything like that.

Yeah, they seriously need to fix the frame pacing. It absolutely drives me insane.

If they could address it, the high-res mode would fantastic. It looks quite good indeed.

The stuttering is so severe.

The game looks so good when you stand still,then you start moving and the stuttering is maddening xO

Like a lot of technical issues, some people just don't notice it at all, and some others are annoyed by it the second it comes.

I have a friend who simply can't see when there's tearing in a game, even huge and obvious ones like in a lot of PS3 games.

If you never noticed stutter in Bloodborne, your eyes are broken.

Here's what I want to know:

If Square-Enix fixes frame pacing, miraculously, even though it seems to be an ever-present issue on PS4... what is the purpose of low-quality mode???

I presume the low quality mode is intended to be 1080p/60fps in the final game.
With the high quality mode faux 4K/ 30fps.

Although I would call any mode with 60fps high quality myself.
 
Frame pacing issues are worse than frame drops for me. If there are some drops here and there, I could live with that, but incorrect frame pacing is hard to deal with. Bloodborne was some tour de force for me, literally. But the game was so amazing I kept playing. Was worth the hassle.
 
I kinda don't want to play this until I get a PS4 Pro, and a 4K TV with HDR.

I have been waiting 10 years for this and I want to experience it in the best possible way, but I don't think I can wait any longer. :/

I've definitely noticed the game lag when there's a bunch of shit going on at once, like when Vicar Amelia sets on fire, but I've never noticed it judder.

Also, I think they're going for 60FPS for the lightweight mode, 30FPS on the HQ mode.

Considering the only company making OLED screens are LG, you may be waiting a while.

Just tried the demo on my new Pro and honestly, even if it's not as bad as say BB and DS3, the framepacing in the HQ mode is pretty noticeable.

Yesterday I played it on OG PS4 and I don't think OG players they miss much without the Pro version. Game is extremely polished on OG.

Now we have to see what they can do to improve the Pro patches.


They're missing a ton of AF and vastly better AA, I say they're missing quite a bit. One of the biggest problems this has on OG ps4 is image quality issues and the pro takes care of that.

I still don't know what I'm supposed to be seeing when people say frame pacing issues. Maybe if I saw it side by side with the XB1 version I would notice?
 
Shadows looked noticeably better in the Light mode or am I crazy?

I think you are seeing the opposite, shadows look noticibly more detailed on HQ settings. I mean it could be slight differences in ToD, but it looks like shadows at a distance have more nuance on HQ/more basic on LQ.

Still stuttering, like it doesn't run with stable 30fps, even if it does.
That's how you could imagine and see it

I can agree with the AF (same as LOD), but the game looks pretty crisp on OG, the IQ is fairly good IMO.

Doesn't help that the AA solution on the HQ mode is pretty bad, but that can be patched I guess.

Haha, just forget it. Bloodborne has the same problem and we always have the same "oh my God, the framepacing is fucking garbage, unplayable, etc" and they all end up playing and enjoying the freaking game.

Don't try to look for it. Some people just enjoy pixel counting and pointing at stupid things than rather play the damn games. Just enjoy it without worrying about anything else besides having fun.

For my tastes, I settled on lightweight mode. While the improved IQ is awesome, the frame pacing is just too severe and hurts the experience.

BD2 takes in a bunch of feedback on social media and their forums. I tweeted your frame-pacing analysis to their twitter accounts.

Nice way to try to dodge the obvious problems a game has.
 
If the framepacing is "as bad" as Bloodborne's, then I'm perfectly fine with it. I didn't even notice it in the game, heck I hardly know what it is. Ignorance is bliss I suppose.

They promissed that Fast mode will have higher framerate, which means we are guaranteed to get at least one performance patch for the game.

Yeah, I only really noticed bad performance in BB when the game started completely stalling [with screeching audio] in short bursts in some areas of the game.
