Missing Windows ARM64 build

[Dual-0]

What feature would you like?

Hi,
I'm interested in running OpenNOW on a Windows ARM device.

I noticed in older releases (such as v0.2.3), a native Windows ARM64 portable executable was provided in the release notes. However, looking at the recent v0.3.6, the release assets only include the x64 binaries for Windows (portable-x64.exe and setup-x64.exe), while Mac still gets both x64 and arm64 builds.

Is it possible to re-add the Windows ARM64 build target to the release pipeline for the latest versions? Thanks for all the great work on this project!

Additional context (optional)

can you try this?

[Dual-0]

can confirm, it is running in ARM64

Does yours run properly? Mine doesnt stream anything when launching a game, like its not receiving a input from Geforce Now Servers.

The App itself gets installed as Arm64.

I tried every Encoding and changed bit Depth, but no Video coming trough.
Windows Build: 25H2
CPU (Surface Pro 10 ARM): Microsoft SQ3 (3.00 GHz)
GPU: Qualcomm(R) Adreno(TM) 8cx Gen 3

I use these settings:

Mouse input lags very hard on my Surface Laptop 13 (Snapdragon X Elite) with both clients x64 0.3.6 and arm64 0.3.2... I am still testing.

Interesting! Seems Super Ultra Wide being buggy with 5120x1440 Resolution, no Video getting returned. When I set 4K it works.
Nvidia themself implemented last September 2025 a Bug, where 5120x1440 doesnt run anymore on ARM. I had a Ticket going back & forth 3 Weeks on the Indian Support till I lost my patience and stopped replying (always got back the same questions, no escalation, even I provided logs with reverse engineering the Bug). Always getting forced to 3840x1080. I tested that on x64 and SUW worked. Will need to open up a seperate Issue.

That Issue was also raised on reddit (Im Lagger_Gandalf): https://www.reddit.com/r/GeForceNOW/comments/1nwnsq7/gfn_no_longer_opening_in_5120x1440_resolution/

Thanks for your reply!

Edit: Created a new Issue for the ARM 5120x1440 issue: #345

[zortos293]

I'll look into this and get it working as soon as possible.
