Subsystem status (v0.1.7)
Verified against Goldoire/fefw-recomp release notes, README.md and the public issue tracker on November 12, 2026:
| Subsystem / Feature | Status | Upstream Notes & Issue References |
|---|---|---|
| Campaign chapters, bases & tactical battles | Playable | Runs natively on Windows and Linux via Vulkan 1.3; battle map frame-rate leak (#69, #85) and infinite loading stalls (#97) resolved in v0.1.7. |
| 60 FPS & 120 FPS modes | Working | Built-in 60 and 120 FPS gameplay clock scaling (#24, #25) without 2x logic speedup. |
| Ultrawide (21:9, 32:9 & wider) | Working | Expands 3D viewport horizontally while keeping HUD and menus centered at 16:9 (#10); minimap and backdrop alignment fixed in v0.1.7 (#40). |
| TAAU, NVIDIA DLSS & AMD FSR 3 | Working | Built-in TAAU plus Streamline DLSS / DLSS-G (#6, #14) and FidelityFX FSR 3 upscaling + frame generation without UI smearing (#20). |
| Joy-Con 2 PC mouse & WASD keyboard | Working | Full keyboard bindings (#16) and native Joy-Con 2 mouse control in bases, battles and menus (#40). |
| DualSense & Switch Pro HD Rumble | Added in v0.1.7 | Wired USB HD Rumble via RenHDrum under F1 > Controls > Haptics (#95). |
| Linux & Steam Deck launcher | Added in v0.1.7 | Native fefw-launcher.AppImage compiles fefw.exe and runs via Proton / umu-run / Wine with Add to Steam (#30, #87, #65). |
| DLC & RomFS mods | Working | Loads dumped DLC from dlc\<title id>\romfs and RomFS file replacement mods from mods\ (#3). |
| Repeated scene transitions (Issue #133) | Under investigation | Repeatedly moving between Dagda and Arena battles can gradually raise GPU utilization; restarting between long sessions clears it. |
| Windowed mode on Radeon 8060S (Issue #100) | Use Borderless | Windowed mode can trigger VK_ERROR_DEVICE_LOST (-4) on Radeon 8060S (ROG Flow Z13); Borderless and Fullscreen work cleanly. |
| ExeFS code mods (.ips / .pchtxt) | Not applicable | Game code is statically recompiled ahead of time (#121), so emulator binary patches do not apply. |
Why update 131072 is required
Static recompilation translates exact AArch64 function addresses and jump tables from the update 131072 executable (Title ID 04007EF01F8AE000, build ID DB93B0125F485060) into C++. A base 1.0 dump without update 131072 has different binary offsets and will display "These game files are a different version" during Set up.
60 / 120 FPS clock scaling
As documented in both Goldoire/fefw-recomp (#24, #25) and Weile10000/FEFW-60FPS (seedds/nxnative), the game’s graphics object at [main+0x21e60d8] stores display rate at +0x1d8 (60) and target frame rate at +0x1dc (60 in menus, 30 in gameplay), while 59 logic readers step animations and movement by 60.0 / target. Simply unlocking the swap interval makes the game run at 2–3x speed; FEFW Recomp updates the internal target rate and exact game clock so 60 FPS and 120 FPS play at normal speed.
Active open issues
- Scene transition FPS degradation (Issue #133): transitioning repeatedly between hub areas (such as Dagda) and Arena battles can increase GPU load over time. Saving and restarting the game restores full frame rate.
- Chapter transition / Dagsion crashes (Issue #123, Issue #130): on integrated GPUs or 8 GB RAM laptops, arriving at Dagsion or clearing a chapter can hit memory pressure. Ensure Texture detail is set to Half size (or Automatic) and update your Vulkan driver.
- Radeon 8060S windowed device loss (Issue #100): if Windowed mode shows a black screen with audio playing (`VK_ERROR_DEVICE_LOST`), switch to Borderless or Fullscreen (Alt+Enter).
Common questions
Can I verify which upscaler and frame generator are actually active in-game?
Yes. In v0.1.7, press F1 and open Graphics > Live render state (#95) to inspect the active upscaler (TAAU, DLSS, or FSR 3), internal resolution, and whether frame generation is inserting frames.
Does Intel Arc XeSS work natively?
Intel Arc GPUs run the game via Vulkan 1.3 and can use built-in TAAU or AMD FSR 3 upscaling and frame generation today; native XeSS SDK integration is tracked as a feature request in Issue #104.
