Arm's Accuracy Super Resolution (ASR) Upscaler Lands in Fortnite

[AleksandarK]

Delivering a good visual experience on mobile devices remains a significant engineering challenge: limited GPU power, stricter memory bandwidth, and tighter thermal constraints all threaten to undermine the game's signature smooth frame rates and high-fidelity visuals. To combat these challenges, Epic Games is partnering with Arm to integrate Arm's Accuracy Super Resolution (ASR) upscaling technology into Fortnite Mobile, also being the first ASR-enhanced title. Rather than overhauling Fortnite's existing rendering pipeline, Epic is embedding ASR through a dedicated Unreal Engine 5 plug-in, which will be compatible with both Android and iOS devices. By leveraging a temporal upscaling approach, which is rooted in AMD's FidelityFX Super Resolution 2 framework, ASR analyzes multiple frames to reconstruct a higher-quality image.

Early demonstrations at GDC 2025 showed that devices using Arm's Immortalis-G720 GPU can achieve up to a 53% increase in frame rates while reducing power consumption by approximately 20%. Consequently, gamers can look forward to longer play sessions without worrying about overheating or excessive battery drain. For Fortnite players, ASR's integration translates into noticeably sharper textures in fast-paced encounters, crisper detail when surveying distant environments, and fewer visible artifacts overall. Importantly, these improvements are achieved without sacrificing artistic intent: Epic's artists and engineers retain full control over color accuracy and visual effects, even as the game renders at a lower internal resolution. Tests in collaboration with MediaTek further confirmed similar power savings on Dimensity 9300 chipsets, addressing one of the most pressing mobile concerns: battery life.

So turning down the resolution scaling is now called upscaling? Interesting

Fortnite isnt the best game to showcase upscaling but i assume they wanted to show the best case scenario and it just looks smudged. this isnt marketing this is the opposite.

My dumb brain spent a minute trying to spot meaningful differences in the split image, before remembering that the point is that there is supposed to be none...
Whoever made those images should have at least added a graph of power consumption or framerate (or even a single number for either) to each side.

Always has been. Up/down scaling does not imply what resolution the source was generated at, it only defines the direction of change (sometimes ambiguously).

It's right there though:

Pic`s looks like GIGO anyway..

I know, hence "remembering that the point..."
My criticism stems from how people usually interpret side-by-side/split comparisons. Maintaining context from body to annex is difficult in the age of the internet (doubly so in that of chatbots).

Both On and Off look as shite.

Both On and Off look as shite.

Jeup, they both do.

The On side does look worse, though, to my eyes.
At least on the Off side, you have some crisp aliasing, the On side is just mushy looking.

yeah but its on a phone is its not that bad, I think the real goal here is to show that it looks AS shit as not having it....but then I guess we have to assume performance is better even though its not shown...... seems a little premature to share if you ask me.
