PS5 “Power Saver” Mode Tested - Digital Foundry

Finally some extensive testing from DF. Still not sure why an end user would bother with this mode, but may shed some light on rumored Canis compatibility for PS5 titles. But given PSSR is being disabled for Days Gone on Pro, I'm not sure this has anything to do with Canis at all, which would presumably lean heavily on AI upscaling.

Instead of getting a PS5 with a newer process node, that would save power and die space, we get a gimped performance mode.

I don't think Canis/Orion can run PSSR 1.0
 
Interesting! Why is that? Does that mean backwards compatibility on Orion can't run Pro versions of the game??
The matrix cores from RDNA5 are completely different from what PS5 Pro is using. Maybe they can find a way to implement BC but I wouldn't bet on it.
K KeplerL2 What do you think Canis (which will presumably have a 1080p screen) could do regarding these games running at 1440p resolution?
Idk, does Sony have a way to change a game's internal or output resolution at a system level? I know Xbox has done that for a few games.

It doesn't, but it makes me wonder if such system level feature is possible. I guess Xbox shows that it is?

PSSR needs 300 TOPs of INT8.

Man, running base ps5 modes on PS6 would absolutely suck. It would make games like FF7 rebirth, AC shadows, GoY, KCD2 etc. a step backwards on PS6. Hope they find a work around to brute force it somehow.

If you have a 1080p screen, all 4K (and supposedly 1440p) games will work and output at 1080p (by downscaling 4k to 1080p). So yes PS5 can downscale anything at system level but not the internal resolution of the game.
 
Most likely a side device coming after PS6.

Don't see them launching a completely new portable before it, to be honest.

Unless they salvage the Portal, build upon that and make it more than a streaming device.

Either way, if you already have a PS5 an android handheld to run retro games and stream current gen ones, sounds more way tempting than a PS Portable.

It should run PSSR 2.0 / FSR4 and hopefully the games with Pro patches get a PSSR upgrade. I see it unlikely that PS6 will play games worse than on PS5 Pro (although they could try to position it in that way I think it would be more trouble than it is worth).

Last I recall PSSR is a system SDK call, not unlike how PSVR comm was implemented - ie. there's nothing saying the system must run PS5 Pro code for it. Ie. it wouldn't need 'BC' it would simply need to swap in its own upscaler - it's analogous to DLL swaps on PC.

That said - can we just stop bending over backwards trying to retrofit the ECO mode into Handheld profile where it clearly isn't it at all?
Like litreally nothing about how this has been implemented is even resembling a handheld-hw profile - from removal of upscalers to targeting 4k outputs and other things (like CPU spec that is overperformed by every handheld release in last 3 years including the Switch 2) - it makes absolutely zero sense and we still have youtubers bending themselves into a pretzel trying to insist

Even in this video DF is still like... but Maybe it's all there we're just not seeing it in plain sight... it's 'the powerbrick GPU' level of leaps at this point...

They always had that in the sense you're referring to - lots of PS4 Pro games specifically ran different depending on resolution for instance.
But neither XBox nor Playstation actually have 'system level' overrides - it's system inputs that the games decide what to do with.
Eg - 90% of PS3/360 games had a special 480p mode - for SDTV only, ie. they run better on SDTVs pretty universally (for people that complain about framerates that gen - try playing on SDTV, I mean - that's what Series S and Switch users still do in 2025 - so clearly it's 'fine').
But some games decided to downscale instead (and usually resulted in borderline unplayable results - but it was a developer choice, never system one).
 
I still don't believe that Sony would be regarded enough to waste resource on a handheld when their arch nemesis in the console space is dead and Nintendo has the handheld/hybrid market on a chokehold with a vastly superior architecture for low power devices.

That's exactly when competition would rise. When one company holds superiority without actual monopoly. It's not a new endeavor for Sony and the rising trend of portables will be something they will want a piece of, even if that doesn't mean global domination.
 
Finally some extensive testing from DF.
Yeah that wasn't extensive. Preliminary sure, but extensive? Most impactful aspect to my mind was they stated they have independently confirmed the MLiD specs in general. (1:22 in the DF OT). Always good to get independent verification.
 
If you have a 1080p screen, all 4K (and supposedly 1440p) games will work and output at 1080p (by downscaling 4k to 1080p). So yes PS5 can downscale anything at system level but not the internal resolution of the game.
Downscaling also keeps the pixel count. So a 4k image downloaded to a 1080p resolution would have 4 times as pixels of a native 1080p image, resulting in a more crisp image due to higher bitrate. But that is the same as running the game on 4k, which wouldn't be possible on the handheld to begin with, thus the need power saving mode and handheld optimized versions of games.

The Switch consoles constitute a "vastly superior architecture for low-power devices"? Are you fucking kidding me here? Sony handhelds have historically mopped the floor with Nintendo's DS and 3DS consoles.

Fucking hell, we've got Hideo Kojima himself on the record saying that the full Metal Gear Solid V was being concurrently developed for PS3, PS4 and Vita -- a console designed by Mark motherfucking Cerny -- and you're coming at me with this "Nintendo's superior" bullshit?

Jensen Huang can suck my dick after the RSX.
