Windows 10: Game developers: Windows 10 ARM64 support is coming to Unreal Engine

Windows 10, ARM64 and Unreal Engine? On the same laptop? Is that a thing?

It soon will be. In this blog, I’ll show how you can get started porting your UE4 games and graphics to Windows 10 on ARM in order to prepare for a targeted version of Unreal Engine.

It shouldn’t be that much of a surprise. Visual C++ compilers and libraries for ARM64 have been available since Visual Studio 15.9. And OEMs like Acer, HP, Lenovo, Microsoft and Samsung have been selling Windows 10 on ARM devices powered by the Qualcomm Snapdragon compute platform.

What may surprise you, though, is that Windows 10 on ARM is suitable for a lot more than just word processing, web browsing and checking email. Miguel Nunes demonstrated Zoom on a https://youtu.be/O5BAPYlK3iA with up to 3x-longer battery life than a comparable x86-powered laptop. And Windows on ARM support for x64 apps on the Surface Pro X is here as well.

Even more surprising is the performance you’ll see when you start porting your UE games to ARM64 and running them on a laptop powered by Snapdragon compute platforms.

But maybe the biggest surprise is that you won’t have to run in emulation.

The icing on the cake: Native ARM64 support for Unreal Engine is coming

Windows 10 on ARM supports x86 (32-bit) and x64 (64-bit) targets with emulation, which gives you a quick way to deploy. Recompiling your code as native ARM64 apps opens the doors to faster processing, more-efficient power consumption and all the advantages of the Snapdragon compute platform and the Qualcomm Adreno GPU.

That’s why we engaged ForwardXP to create an ARM64 version of the venerable Infiltrator Demo as a proof of concept. While this demo is several years old now, it was created with the purposes of showcasing the capabilities of Unreal Engine 4 with high-end content. To this day, the demo still demands a lot from even a high-end, discrete PC GPU for credible, real-time performance.

We put ourselves in your shoes and decided to optimize the content of the demo itself rather than the core engine. Why? Because it better represented the journey you would take in porting your games to ARM64 and in scaling the performance for a wide range of hardware.

Besides optimizations to the demo content, the project required development work to add Windows 10 ARM64 support to Unreal Engine 4.23. For more information on targeting Unreal Engine for Windows on ARM64 visit the Unreal Engine for Windows on Arm64 tutorial in our Game Developer Guide.

Unreal Engine launcher bug

When i go to open the “Epic Games Launcher” to open unreal engine 4 it just says its loading and then doesn’t open

could someone help

here’s a video i made about this:

 

Help needed with Unreal Engine games stuttering on my rig

It seems that on my rig I have a stuttering issue with some Unreal engine based games. Some of them just seem to stream really badly whereas others are flawless, it's really hit and miss. Most notably and recently the problem games have been "Bulletstorm & Alice: Madness Returns".

Here's a full list of the games which stutter on my rig using the Unreal Engine

Alice : Madness Returns
Bulletstorm
Blacksite - Area 51
Wolverine

Games which use the unreal engine and play fine without any issues (on my rig) -

Bioshock 1 & 2
Batman AA
Duke Nukem Forever
Borderlands
Gears Of War
BIA - Hell's Highway
Mass Effect
Singularity
Mirror's Edge
Medal Of Honor Airborne
Rainbow Six 1 & 2

I'm looking for any major things I can do to optimise the engine to work better with my current setup. I will update the first post with your suggestions so it can also help others in the future.

Thanks in advance for any suggestions.
