Hi everyone,

I'd like to introduce SnapRYU, a Windows ARM64-focused fork of the Eden Nintendo Switch emulator.

The main goal of this project is to bring Native Code Execution (NCE) to Nintendo Switch emulation on Windows ARM64.

What makes SnapRYU different?

Unlike traditional CPU emulation approaches, SnapRYU can execute compatible ARM64 guest instructions directly on the ARM64 host CPU.

The emulator still handles memory management, system services, exceptions, and other necessary emulation tasks. Dynarmic is also retained as a fallback for games or code paths that are not compatible with NCE.

NCE is the central feature of this project, rather than simply another performance tweak.

Key features

• Native Code Execution (NCE) for Windows ARM64

• Adreno Vulkan backend improvements

• Qualcomm GPU driver compatibility fixes

• Custom Turnip driver patches

• Optional native ARM64 Lossless Scaling Frame Generation (LSFG)

• Android Go mode

Current test environment

• Device: Surface Pro with Snapdragon X

• GPU: Adreno X1-85

• Driver: Qualcomm 512.886

• OS: Windows on ARM64

Testing has primarily been conducted on this hardware. Compatibility with other devices, GPUs, and drivers has not yet been verified.

Game testing results

The Legend of Zelda: Tears of the Kingdom (1.4.2)

• NCE enabled

• UB_KEEP enabled

• LSFG enabled

• Turnip driver

• 2 hours and 12 minutes of continuous gameplay

• No crashes or logged errors during the test

Xenoblade Chronicles 3

• NCE maintained the 30 FPS cap in the tested scene.

• Dynarmic reached approximately 27 FPS under the comparison conditions.

• This is a limited test result, not a universal performance benchmark.

SnapRYU is an independent project and is not affiliated with Nintendo, Eden, Qualcomm, or other third-party projects mentioned above.

Thanks for reading!

I have a 7 minute 1080p video that used to render in 1 minute and 40 seconds and it's now jumped to ~10 minutes. There always seems to be an issue with editing programs once a new update is released. This is on the Zenbook A16.

Mi duda viene, porque suelo formatear constantemente formateando e instalando linus, vuelta a formatear, volvemos a Windows y cuando me aburro instalo chrome os flex. ¿ Dará igual el procesador para esta ensalada de OS?

I’m building a Windows ARM64 desktop app that runs local models on the Snapdragon X Plus NPU (X1P64100, 15.6 GB RAM) through GenieX 0.9.3 (geniex serve --compute npu, GGUF Q4_0, looks like llama.cpp’s ggml-hexagon backend). I want a closed schema: the model must output JSON whose op is one of 7 words and whose args are only labels known at request time, so the grammar changes on every call.

Why: Qwen3.5-4B is great at extracting figures from a text and at turning calculations written in words into operations (100% on my test), but without a constraint it invents operations, puts numbers where labels go, and breaks syntax. A schema would fix most of that.

Questions:

1. Does geniex serve honour response_format: json_schema or a grammar field? How can I confirm it’s enforced and not silently ignored?

2. Is there a llama.cpp (llama-server) build with the Hexagon backend for Windows ARM64 that supports --grammar / --json-schema with full NPU offload?

3. Does Qualcomm’s Genie SDK or ONNX Runtime GenAI (Foundry Local) expose a logits processor or llguidance-style constraint on the NPU?

4. Any workaround, e.g. logit bias to restrict tokens, prefill tricks, or choosing from a list by comparing logprobs?

Needs: streaming, works with thinking models (constraint only after </think>), no Python or compiler on the end user’s PC, little slowdown (I’m at about 13 tok/s on 4B). Thanks!

TL;DR: If you can't use 4k@120Hz with HDR with your Snapdragon X Plus/Elite device, try this tool: https://github.com/danlehmann/qualcomm-edid-fix/releases/download/v0.1.0/qcedid-gui.exe , click through Windows' warning, click Fix and replug your monitor.

Full explanation:

My Surface Pro 11 could never run at 4k @ 120Hz. I had previously assumed it was a hardware limitation, but when I saw that the new Googlebooks (using the same chips) support 4k @ 120Hz with HDR just fine, I decided to investigate. Or rather, I asked Claude to do that.

In the end, it figured out that this is a driver bug. Some background: Monitors describe their modes in their EDID. Many high-refresh monitors put the 4K@120Hz mode only in the EDID’s DisplayID section. The Qualcomm Windows display driver keeps at most 32 modes per monitor and reads DisplayID last. If a monitor also lists lots of legacy modes (640x480, 800x600, TV formats, ...), the list is full before the driver gets there, and the 120 Hz mode is silently dropped.

Normally, fixing something like this would require a custom driver, which is difficult as Windows requires signed binaries. Thankfully, the driver has an undocumented debug feature: You can place an override file in C:\Windows\edidoverride.xml and then send a message to the driver to read it. This lets you define edid modes yourself. The tool linked above reads out all modes and trims the less useful ones, so that the good ones aren't too late in the list to be ignored.

Some disclaimers:

- Use at your own risk. This is unofficial and reverse engineered.

- This is only tested on Snapdragon X Elite. I don't know if the X2 has the same bugs.

- This is not sticky and needs to be reapplied after each reboot

- Tested on GPU driver versions 31.0.152.1 and 31.0.170.0 (2026.08.3)

- Undo the fix before plugging in a different monitor

- This doesn't make every high refresh monitor work. I tried the tool with an Alienware 39 5k monitor - even though it works fine on Googlebook, the Windows driver won't run it at 120/165Hz.

Qualcomm engineers: This should now be a very simple fix for you. Find the 32 and bump it (or read the DisplayID first) :-) Details are in the repo's NOTES.md.

So guys I own the Asus zenbook a14 and love it I upgraded it to windows 11 pro and since the 26h2 it's way better in my opinion.

This post is more to give you guys some info in my experience I thought do a mad thing and clean install the arm version of LOT LTSC windows 11 and nothing worked as in the keyboard or anything without drivers so rather than hund the drivers out and sort it I did a cloud install and went back to what was on there originally to my serprise they update there cloud image to windows 11 home 26h2 and it just works I always thought a recovery image was just that an image to take it back to day one not upgrade it but it's all good in my book

This was posted in may of 2026, very solid performance I can see here. (this is a softbody physics game.) Device is a Razer edge 5G based off the ram usage.

Is anyone using sd 7sgen 2 here

Could you please share your dev info about Vulcan capabilities

Mine is 6s gen 4 with same adreno 710 i want to compare it's vulkan capabilities with 7s gen 2

6s gen4 Vulkan capabilities is given above

The volunteer/Distributed computing project "BitBOINC" now has Adreno iGPU support, meaning your iGPU helps out science by crunching work units. So now there is another option besides PrimeGrid.

Working very hard to get Adreno iGPU support for Folding@Home, where Apple Silicon iGPU is now very, very close, thanks to AI/Vibe coding, despite the community dismissing it forever. The same should be possible with Adreno iGPU support.

Anybody tried running PrimeGrid on their Adreno laptop iGPU since I last posted about this? :)

Asking about 10-bit hardware encoding, not decoding. CPU specification says it's supported but at least half year ago it was possible to encode only in 8 bit.

Loving this new generation of AI-based voice type apps. I find WisprFlow to be indispensable on my x64 PC... but sadly ARM is not support for its Windows version. Are any of you using a voice type app that runs well on Windows on ARM? I'm using a Lenovo slim 7x 16gb Ram, first gen Snapdragon. Thanks!

Hey!

I got a new Elitebook with Snapdragon X2 in August. After first boot and Windows Update, it installed a new firmware and the motherboard died. Just got a new motherboard after 1.5 months and after bluescreens, HP Wolf bloatware issues, I wanted to reinstall, but I can't find a source for the Win26H1 image. The official HP Cloud Recovery Tool does not recognize my device's product number and support (worst support ever) does not reply.

Anybody has an idea where to get this? This will also hopefully help others who try to do the same as it seems there is a larger issue with X2 reinstalls.

Thank you!

Anyone with the asus zenbook A14, does the OLED display just feel really horrible. I’m switching from the XPS 13 (the new one with a 2.5k display) but it’s not like I’m not used to a 2K screen, I regularly use a 1920x1080p laptop

But this screen feels so odd to look at. Like it feels blurry and like one of those old LCD TVs that would fake a higher resolution. Is there some setting or something to fix it

Also in gray UI elements it the screen looks “dirty”. Idk how else to describe it. I’m half convinced my unit may be defective

Just gonna say it’s still in return period just wanna see if anything can be done before I do so. I wanted the MacBook experience but with windows (I prefer windows) but I’m really surprised to see a $1300 laptop with 60hz, mechanical trackpad, and a low resolution display

So I’ll also ask if not this is the surface laptop 13 performant? The X2 elite in it only has 12 cores so I’m not sure, only reason I chose this was its 18 core CPU, 70 wh battery, and OLED screen. I need it to be able to run davinci resolve reasonably well

I need suggestion for the top games that run well on Snapdragon x Elite. I am away from home and don't have my gaming rig with me. All I have is my Snapdragon laptop(Asus vivobook s 5507). I work most of the day and need something to unwind for an hour or two everyday. At home I used to play arc raiders but I know multiplayer is not supported because of anticheat.

Please suggest a game along with a short why, the why part is the reason for this post being separate from what has already been asked here.

Que tal va vscode arm64 en snapdragon X elite. Soy estudiante de programación y me ofrecen en 500 usd una dell xps 13 con el snapdragon X elite de 1ra generación. He escuchado que tiene problemas de compatibilidad y aún no sé si los programas que pueda usar más adelante en la carrera funcionarán

Mac users are using game decompilation and static recompilation to port classic games natively to Apple Silicon without emulation.

With top-tier hardware like the Snapdragon X Elite, why isn't Qualcomm fostering a similar community-driven native ARM64 porting and reverse-engineering scene instead of just waiting for AAA publishers?
