Following the Nintendo Direct, Sq. Enix launched a free demo for Kingdom Hearts III + Re Thoughts DLC on Nintendo Swap 2. As somebody who has performed Kingdom Hearts III over time throughout principally each platform, I used to be curious to see how this new native launch would look and run. That is the primary present platform launch of Kingdom Hearts III and there may be potential to scale nicely above the unique PS4 and Xbox One ports given the Swap 2’s {hardware} capabilities. Having now tried the demo, I’m upset with the efficiency within the demo, however there are some points that impressed me. Since this can be a demo, there’s an opportunity the complete recreation sees efficiency enhancements like with Closing Fantasy VII Rebirth, however that continues to be to be seen right here.

Since I can be doing a full comparability nearer to the brand new console launch for the Kingdom Hearts collection on PS5, PS5 Professional, Xbox Sequence X, and Swap 2, I made a decision to deal with the newest variations of Kingdom Hearts III I performed when trying on the Swap 2 demo. I replayed the opening hours throughout the PS4 (on PS5) model, PC model on Steam Deck, and the Swap 2 demo each docked and handheld. I will cowl visible variations between the Swap 2 and PS4 variations, Swap 2 handheld expertise in comparison with Steam Deck, and what I hope to see Sq. Enix deal with past simply optimization.
Kingdom Hearts III Swap 2 vs PS4 and state of the console variations
Kingdom Hearts III is getting a local PS5 and Xbox Sequence X launch when it arrives on Swap 2 in October, however the demo is just on Swap 2 in relation to present platforms. Again when Kingdom Hearts III launched, I ended up enjoying it on Xbox One X as a substitute of PS4 Professional due to the VRR assist. The PS4 Professional model felt unhealthy to play except you compelled the console to 1080p. The PS4 base launch felt too unstable for my liking. When the PS4 and Xbox One variations are performed on PS5 and Xbox Sequence X respectively, they ship locked 60fps experiences utilizing PS4 Professional and Xbox One X visuals. Because of this till now, the easiest way to play Kingdom Hearts III on console is the Xbox One model on an Xbox Sequence X. You get crisper visuals than the PS4 on PS5 launch and a locked 60fps.
Observe: For the docked and PS4 on PS5 comparisons, I used my 4K seize card to get PS4 on PS5 and Swap 2 docked gameplay captured. I cropped the pictures to point out how each platforms are.
The PS4 Professional model was softer than Xbox One X delivering a sub 1440p expertise. Within the few areas I measured when enjoying it on PS5 through backward compatibility, I received a 1296p studying which is smart given it was the higher restrict again at launch on PS4 Professional as examined by Digital Foundry.
Preserving all that in thoughts, I hoped the Swap 2 launch would match or exceed the Xbox One X model given the {hardware}, however what we’ve got is a port that goes above PS4 Professional in some points, and beneath in others. Relating to picture high quality, Kingdom Hearts III has a dynamic decision primarily based on the opening hours on Swap 2 docked. Within the 4 places I examined, I used to be getting outcomes between 1080p and 1296p, however I might not use these as laborious numbers as I didn’t take a look at each single location and this isn’t the ultimate construct. This traces up with the PS4 Professional model somewhat than the Xbox One X model.

Relating to efficiency, Kingdom Hearts III on Swap 2 sadly simply runs uncapped between 30 and 60fps. It could possibly hit 60fps in much less demanding areas and should you take a look at a wall and transfer the digital camera, however it is vitally a lot an uncapped expertise throughout precise gameplay. Even some places later that run at the next common body fee by no means hit a locked 60fps. Relying in your tolerance for this, you could possibly play it with out points, however I might have favored an elective 30 or 40fps cap right here along with higher optimization. We have seen many older video games run so much higher than the PS4 and Xbox One variations when performed docked on Swap 2. Hopefully that is simply an early construct, however proper now I am glad with how Kingdom Hearts III seems to be and masses on Swap 2, however the efficiency leaves so much to be desired. The realm it does excel above PS4 Professional, is in load instances which I’ll cowl beneath.
Kingdom Hearts III Swap 2 vs Steam Deck handheld
I assumed Kingdom Hearts III could be higher handheld with the VRR show, however it sadly is simply too unstable for my liking proper now in relation to efficiency. Visually, Kingdom Hearts III has a dynamic decision handheld and it may drop to 720p in my testing with different outcomes round 900p. Once more, I need to stress that I solely pixel counted a number of places and can save extra checks for once I get the ultimate recreation. I simply wished a tough thought to see the place the present construct ended up on the spectrum. Even with that dynamic decision vary (and a local 1080p UI), Kingdom Hearts III seems to be good on the gadget itself.
For some background, Kingdom Hearts III on Steam Deck can not ship a locked 60fps expertise at a full 720p output even on the low preset. Once I replayed Kingdom Hearts III on Steam Deck for the collection’ Steam debut, I ended up choosing a 40fps on Steam Deck LCD and 45fps on Steam Deck OLED cap with tweaked settings. Having a secure body fee, even at 40fps, is so much higher than an uncapped and variable 30s to 50s common vary you get right here.

Observe: For the comparability above, I used the Steam screenshot performance on Steam Deck and the Swap 2’s system seize performance. I then cropped the pictures to point out the identical location on each platforms. I additionally examined the Steam Deck on the excessive preset at 720p which resulted in a 50-55fps expertise right here.
Kingdom Hearts III’s demo has some places that run nearer to 60fps, however it stays the exception proper now. Since Kingdom Hearts III is a final technology recreation, I anticipated higher for the port given the Swap 2 {hardware}. Once more, a 40fps handheld expertise ought to be a given for final technology video games like this, however the port’s efficiency leaves so much to be desired.
Proper now, Kingdom Hearts III handheld delivers a greater trying expertise on Swap 2, however a extra secure expertise on Steam Deck. I even downloaded Kingdom Hearts III on my different Steam Deck to make certain of the efficiency as a result of I used to be linked to some video the place the low preset was barely holding 30fps on Steam Deck. I can verify that I used to be simply in a position to get a 45fps at 90hz expertise utilizing the medium preset. The excessive preset was nearly an ideal 40fps expertise as nicely. Within the 4 areas I examined throughout the sport, I used to be even in a position to get a 30fps lock at max settings, although I’ll save definitive Steam Deck suggestions for once I do my full comparability nearer to the Swap 2 native launch. Proper now, I would stick with medium for 45fps on Steam Deck OLED.

Kingdom Hearts III load instances in contrast on Swap 2, Steam Deck, and the PS4 model examined on PS5
To check load instances, I put in Kingdom Hearts III on the PS4 Professional laborious drive, the PS4 model on PS5 exterior laborious drive, the PS4 model on PS5 inside storage, the PS4 model on PS5 Professional inside storage, the PC model on Steam Deck inside storage, and the Swap 2 model on the Swap 2 inside storage. Kingdom Hearts III has quite a lot of compelled splash screens to start with inflating the load instances. Along with the dashboard to title display, I examined the time taken to load an early save file on all platforms. The outcomes beneath are in seconds.
| Platform | Dashboard to title | Loading save |
| Swap 2 Demo | 32 | 23 |
| PS4 Professional | 45 | 38 |
| PS4 on PS5 HDD | 34 | 32 |
| PS4 on PS5 SSD | 31-34 | 24-26 |
| PS4 on PS5 Professional SSD | 32 | 25-26 |
| Steam Deck | 40 | 26 |
As you’ll be able to see, the native Swap 2 demo construct masses the save quicker than the PS4 model on any console and the PC model on Steam Deck. It additionally masses the title display as quick because the PS4 model working off an SSD. The Swap 2 demo construct is a giant enchancment over the PS4 model performed on PS4 or PS4 Professional consoles and it additionally masses quicker than the Steam Deck. It stays to be seen how the PS5 and Xbox Sequence variations load given they are going to be native builds for SSD-only platforms. Both manner, this can be a good outcome for Swap 2.

What Sq. Enix wants to repair in Kingdom Hearts III on Swap 2 for launch
If Sq. Enix needs to ship a PS4 Professional tier visible expertise on Swap 2, it must do higher in efficiency. I wish to see a 1440p 30fps mode and a dynamic decision 60fps mode docked a minimum of. Sq. Enix also needs to look into doing a secure 40fps at 120hz handheld mode on Swap 2. Proper now, I am advantageous with the visuals being just like PS4 Professional, however efficiency leaves so much to be desired. Hopefully we see enhancements within the closing construct and a patch for the demo nearer to launch.
Kingdom Hearts III is now out there on PS4, Xbox One, and PC (Steam). It launches on October 8 for PS5, Xbox Sequence, and Swap 2.
