Pokémon Scarlet and Violet on Kenji-NX — Settings & Performance Guide
Pokémon Scarlet and Pokémon Violet are the first fully open-world Pokémon games — and famously some of the worst-optimized Switch titles ever released, with performance complaints even on real hardware at launch. That reputation follows them into emulation: on Kenji-NX they are playable on good hardware, but expect dips, especially in busy towns and during weather effects. This guide sets realistic expectations, gives you the settings that matter most, and covers the issues players report most often.
Legal note: Kenji-NX does not include any game files. You must own Pokémon Scarlet or Violet and dump it from your own Nintendo Switch. This site does not provide game downloads, keys, or firmware. New to the emulator? Start with our download page and the setup guide.
Can Kenji-NX Run Pokémon Scarlet and Violet?
Short answer: yes, on a capable phone — with caveats. Because these games struggled on the Switch itself, “playable” here means a generally smooth adventure with noticeable slowdowns in the worst spots (Mesagoza, heavy rain, large wild Tera raid lobbies), not a locked 30 FPS everywhere. Kenji-NX’s accuracy-focused Ryujinx lineage helps with rendering correctness, which matters for a game with this many visual quirks.
What matters most:
- Your SoC. Snapdragon 8 Elite and 8 Gen 3 / 8 Gen 2 with a current Turnip driver give the best results. Snapdragon 8 Gen 1 is workable with lowered settings. Exynos and MediaTek Dimensity phones are not recommended — no Turnip support (Adreno only), so you’re on the stock driver.
- Fresh sessions. Scarlet/Violet are known for degrading over long play sessions (memory pressure builds up). If the game gets progressively choppier after an hour, save, fully close Kenji-NX, and restart — this simple habit fixes more “performance bugs” than any setting.
- RAM. 8 GB is the practical minimum; 12 GB or more is strongly recommended for these titles. Android killing the emulator in the background mid-session is a classic cause of lost progress — save often.
Recommended Settings for Scarlet and Violet
Start here, then change one thing at a time. (Menu names can differ slightly between Kenji-NX builds — the concepts are the same.)
| Setting | Recommended | Why |
|---|---|---|
| Graphics API | Vulkan | Best performance and compatibility on Android; required for custom Turnip drivers. |
| Resolution scale | 1x (handheld) | This game is CPU-heavy in towns; raising resolution only adds GPU load on top. Keep 1x unless you have an 8 Elite / 8 Gen 3 with thermal headroom. |
| Custom GPU driver | Latest Turnip (Snapdragon only) | Reduces texture pop-in and visual glitches on Adreno GPUs. See our driver guide. |
| VSync | On | Prevents tearing; the game targets 30 FPS on real hardware, so there’s nothing to gain by disabling it. |
| Shader cache | Enabled | Smooths out repeat visits to areas as compiled shaders accumulate. |
| Anisotropic filtering | Auto or 4x | Cleans up ground textures at grazing angles; cheap on flagship GPUs. |
| Audio backend | Default | Audio stutter here is almost always CPU load or throttling, not an audio setting. |
| Docked mode | Off (handheld) | Lower target clocks are kinder to phone thermals; the visual difference on a phone screen is minimal. |
Turnip GPU Drivers: Snapdragon Only
Turnip is the open-source Mesa3D Vulkan driver for Qualcomm Adreno GPUs, loaded through Kenji-NX’s custom driver mechanism instead of your phone’s stock Qualcomm driver. For Scarlet/Violet it mainly helps with visual correctness — fewer texture glitches, less pop-in, more stable frame pacing — rather than raw speed, since this game’s bottlenecks are often CPU-side.
The limitation: Turnip only works on Snapdragon (Adreno) phones. MediaTek Dimensity (Mali) and Samsung Exynos (Xclipse) devices can’t use it, and for these particular games the gap between Turnip and stock drivers is very noticeable. That’s a big part of why non-Snapdragon phones aren’t recommended here.
Check our Turnip driver guide for current builds and installation. If a new driver version introduces fresh glitches in Paldea, roll back — driver regressions are real, and “latest” isn’t automatically best for every game.
Snapdragon 8 Elite vs Older Chips
Kenji-NX 2.1.0 brought Snapdragon 8 Elite (Adreno 830) specific fixes — GPU stability, synchronization, and memory improvements — making the 8 Elite the current best chip for these games on Kenji-NX. (Note the history: the Adreno 830 initially lacked Turnip support and could trail the 8 Gen 3 in some emulators; community Turnip builds for the 8xx series caught up through 2026, so use a recent driver.)
- Snapdragon 8 Elite / 8 Gen 3: best experience; towns will still dip, but the open world is generally smooth.
- Snapdragon 8 Gen 2: solid; mature Turnip support; keep 1x resolution and restart the app for long sessions.
- Snapdragon 8 Gen 1 / 8+ Gen 1: playable; expect heavier dips in Mesagoza and raids; manage heat aggressively.
- Exynos 2400 / Dimensity 9000-series: not recommended — no Turnip, and these titles are among the worst cases for stock drivers.
Known Issues and Workarounds
Issues commonly reported by players — results vary by device, build, and driver:
- Slowdowns in towns (especially Mesagoza): the game’s heaviest CPU scenes, slow even on real hardware. Lowering resolution won’t fully fix CPU bottlenecks; keeping the phone cool helps more.
- Performance degrades over long sessions: save, fully close Kenji-NX, and relaunch. This is the single most effective “fix” for Scarlet/Violet.
- Texture pop-in and flickering: usually driver-related on Snapdragon — try a different Turnip build.
- Black screen on boot: almost always missing or mismatched firmware/keys. Re-check the setup guide and make sure your dumped files match the game version.
- Crashes during Tera raids or heavy weather: peak load moments. Close background apps, drop to 1x resolution, and avoid playing while charging (heat).
- Lost progress: the game autosaves, but emulator crashes don’t care — manually save at Pokémon Centers regularly and back up your save folder before updating builds.
Frequently Asked Questions
Are Scarlet and Violet fully playable on Kenji-NX?
On a good Snapdragon phone, yes — the main story and post-game are completable, with the usual emulator caveats. These were never perfectly smooth games, even on Nintendo’s own hardware, so set expectations accordingly.
Which version runs better, Scarlet or Violet?
They’re the same engine and perform essentially identically. Pick the one with the Pokémon you prefer — there’s no meaningful emulation difference between them.
Do I need Turnip drivers?
On Snapdragon: highly recommended for visual stability. On Exynos/Dimensity: unavailable — another reason those chips struggle with these games.
Where can I download the game?
We don’t provide game downloads, and neither does Kenji-NX. Buy the game and dump it from your own Switch. Downloading game files you don’t own is piracy.
The game was fine yesterday and slow today. What changed?
Most likely heat or a long session: thermal throttling after extended play, or accumulated memory pressure. Let the phone cool, restart Kenji-NX fresh, and the performance usually returns.
Can I play online or trade with other players?
Online play on Switch emulators is unreliable at best and can risk your Nintendo account if done wrong. Treat Scarlet/Violet on Kenji-NX as an offline single-player experience.
Next steps: grab the latest build from our download page, follow the setup guide to install firmware and keys correctly, and install a current Turnip driver via the driver guide. Start at 1x resolution, restart the app between long sessions, and save often.
