What's changed

Fire Emblem's DLSS ghosting, a minutes-long Intel shader compile in Mario Kart World, Splatoon Raiders' yellow tint, and a batch of shader and build fixes.

• Fire Emblem: Fortune's Weave no longer ghosts at 1x (#535, fixes #520) — Switch 2 compute programs get their storage-buffer size from the memory behind the pointer (capped at 8 MiB and clipped to the mapping's contiguous range) instead of from the word that follows the address. In Fortune's Weave's DLSS that word is a texture handle, so the buffer feeding the network the current frame was bound as 266 bytes and everything past it was dropped: the network mostly saw empty input and kept blending in old frames, giving moving characters see-through trails and smeared shadows. Older NVN-style buffers and graphics shaders keep the old sizing, and there was no frame-time change in testing.
• The "Use the game's own DLSS" checkbox is gone (#535) — with the ghosting fixed, the game's own DLSS simply runs at 1x unless NVIDIA DLSS is turned on, so the checkbox and the status line under it were removed from the Graphics tab as confusing. FSR 3.1 still takes over on its own with resolution scaling, on GPUs that can't run the network, and if the network's output fails its health checks. EDEN_NX2_DLSS_REPLACEMENT still forces the replacement.
• No more multi-minute compute compiles on Intel — every compute pipeline asked for a required subgroup size of 32 whenever VK_EXT_subgroup_size_control was present, even for kernels that never look at a lane; on Intel that compiles SIMD32 unconditionally and a register-heavy Mario Kart World program spilled badly enough to take minutes instead of milliseconds. The fixed size is now only requested for shaders that use warp-level operations (vote, invocation id, shuffles, mask, quad shuffles), and the required-subgroup-size struct is only chained when the device lists the compute stage in requiredSubgroupSizeStages (#475).
• Splatoon Raiders' scene is no longer yellow — FP16 texture results come back as c0 in the low half and c1 in the high half, and the merge into the destination needs the high half first. The halves were swapped, so every destination ended up with H0 = c1; Splatoon Raiders reads only .H0 for its blue component.
• One more pipeline saved in Donkey Kong Bananza (#492) — the SPIR-V backend only knew how to emit a Phi for U1 and U32, so a F32x4 Phi threw Phi node type F32x4 is not implemented and dropped the whole graphics pipeline (four times per session). Every type the emit context already has an id for is mapped now. This is one wall among several for that title, not a playability fix: Bananza still ends its boot on unrelated IR errors.
• Pokopia's large scene shader compiles (#145) — UISETP that combines its result with another uniform predicate (AND/OR/XOR, including a negated accumulate predicate) and FSETP whose second operand sits in a uniform register are both lowered now, so that shader is no longer rejected. No visible change was identified from it: the black sky it was found while chasing turned out to be fixed by #125.
• Hyrule Warriors UISETP regression caught before it shipped — the accumulate-predicate change also rejected any UISETP whose bits 68-71 aren't PT, a field nx2 never read (only the .EX form does, and that is still rejected). The check is dropped again.
• Generic attribute bound — IsGeneric now spans Generic0X…Generic31W instead of stopping at 31X, so a W component is recognised as a generic attribute.
• Clean MSVC Release builds finish (#429) — the vendored zstd tripped /we4505 and nvhost_gpu.cpp tripped /W4 on a LOG_TRACE-only binding, so a first-time Windows build produced no executable at all. The warning is demoted to /w4505 (still visible), the binding is [[maybe_unused]], and neither change alters generated code.
• Game list tooltip — NUP titles now show their update's display version (Update (x.y.z), read from the NACP) alongside the patch versions.

Automatic build of nx2 at 3081c8e.

Linux

Linux packages come as an AppImage (self-contained, needs glibc 2.39 or newer: Ubuntu 24.04, Fedora 40, Debian 13, Arch) and a tar.gz (uses your system libraries, so Qt 6 and the usual libraries must be installed).

Windows

Windows packages are in-place zip files: extract and run eglantine.exe, or eden-cli.exe from a terminal.

macOS

The PGO builds are the same programs compiled with profile-guided optimization (clang plus Eglantine's profile); prefer them when your CPU supports it.
