video_core: replace Fortune's Weave's DLSS with AMD FSR 3.1

2026-11-02T21:28:01+00:00

Fire Emblem: Fortune's Weave's DLSS network can't run here, and the temporal stand-in is only an approximation of it. FSR 3.1 takes the same inputs DLSS does: the jittered colour, motion vectors, the jitter and the depth, which the game's first DLSS pass reads through cbuf0+0x298 (Z32, reversed, the colour's size). Kepler compute keeps it next to the motion vectors. Fsr3Upscaler ports the host side of the SDK's ffx_fsr3upscaler.cpp: the eight passes (prepare inputs, luma and shading-change pyramids, shading change, reactivity, luma instability, accumulate, RCAS), the internal images and the constants, recorded through the scheduler with the shaders from externals/FidelityFX-SDK. It takes HDR colour, render-size motion vectors and reversed depth, computes its own exposure, and uses the no-wave SPD variants on devices without compute quad operations. The SDK's GLSL uses separate textures and samplers, so DescriptorBankInfo gains sampled image and sampler counts (default 0). FSR's RCAS follows the RCAS Sharpness slider. The result goes to FSR's own RGBA16F image and is drawn into the game's output, which keeps its format. TextureCacheRuntime::TemporalUpscale runs FSR 3.1 first. Without the depth, at mismatched scales, on a device lacking FSR's formats or features, or if its pipelines fail to build, the stand-in runs instead, and the bilinear blit stays last. EDEN_NX2_DLSS_REPLACEMENT=standin forces the stand-in. A gap of more than 250 ms between evaluations restarts the history. The BlitColor overload that takes a raw image view transitions its source to SHADER_READ_ONLY_OPTIMAL but described it as GENERAL in the descriptor (a validation error); it now describes the layout it uses.

vulkan: submit native work sooner and use the active draw count

2026-11-02T19:07:53+00:00

Adapted from sylvieistaken/selevet-eglantine performance builds, including 8b076b167ffc5ca1ba8ffedcd00e255accbe018c and d8c95fef. Preserve upstream command-list coherency and submission ordering. Assisted by Codex.

shader_cache: batch memory-write invalidations without skipping ranges

2026-11-02T18:58:54+00:00

Adapt the batching from ymatrix1/Eglantine PR #237, retaining all CPU invalidations. Acquire the lock once and remove pending shaders once per write batch. Compare real cache contents with sequential invalidation across randomized overlapping writes and pending removals. Assisted-by: Codex (implementation, review, commit text and automated validation) (cherry picked from commit b65f818d7789ffadfb58fe4543b18060fd88ce53)

nx2: read GPU-written command lists from copies instead of draining

2026-11-02T16:24:19+00:00

The trees fix (#52) drains the split and flushes for every command list on a GPU-written page: in a Mario Kart World race ~13,500 lists and ~400 GPU round trips a second, during which the back has nothing to do. The replay ran at ~40 fps instead of ~45. The front now marks the pages those lists are on. The buffer cache notes writes to them; after a compute dispatch or DMA copy that writes one it copies the page into host memory and submits. The front waits for the back only up to the last compute or copy work it sent (not everything queued), then reads the copy once the GPU is done with it. Pages the GPU wrote once, long before, and the CPU now writes lists to have no copy: their first list drains and flushes the whole page, which is then read from guest memory until GPU work writes it again. CPU writes and inline uploads reach guest memory, so they keep such a page synced but make a copy stale. A page a draw writes always drains. Mario Kart World time-trial replay, Radeon 780M: ~40 -> ~45 fps, trees drawn, no list drains left.

Merge nx2 into nx2-experimental

2026-11-02T13:43:01+00:00

Resolved by area: - audio feature_support.h: nx2's native revision handling. - fiber.cpp: ours, which also drops the unused rewind stack. - host_memory.cpp: ours granule bitmap and HintCold, plus nx2's fallocate hole punching per whole dirty granule on Linux. - texture_cache.h: nx2's old-age eviction pass, then our Collect(). - kepler_compute.cpp: shared upscale slots, then Fortune's Weave's, then the Kirby Air Riders scan. - nx2_gsv.h: ours, plus nx2's GetBufferMaxResolution and graphics device ids (1-based). - nvhost_ctrl_gpu.cpp: engine support flag bits 40-44. - lower_to_maxwell.h: ours as the base, with nx2's seven lowering commits applied one at a time. Second texture descriptor buffers are read bindless in TEX, TLD.SCR (level zero) and SUST; FSEL keeps its operand modifiers; TXD takes any channel mask. lower_to_maxwell.h lowers 837 Fortune's Weave and 1183 Mario Kart World shader dumps with the same rejects as nx2 and ours (12 and 0).

vulkan: repack 69-byte vertices to 72 bytes (#281)

2026-11-02T07:38:47+00:00

Splatoon Raiders draws with a 69-byte vertex stride and a packed 4-byte attribute at byte 65. Those fetches are unaligned, which Vulkan leaves undefined: NVIDIA reads them as meant, the AMD Windows driver does not, and the outdoor scenes turn into a white haze with horizontal streaks. When a binding uses that layout, a compute pass copies it to a 72-byte stride with the tail moved to byte 68, and the vertex input offsets and stride follow. EGLANTINE_TEST_VERTEX_REPACK=0 turns it off; EGLANTINE_EXPERIMENTAL_STATIC_VERTEX_REPACK=1 also covers pipelines without dynamic vertex input. Based on an outside patch (02-portable-vertex-repacking). Changes from it: a range over the device limits skips the repack instead of throwing, and the pipeline cache version stays, so caches are kept.

video_core: temporal upscale stand-in for Fortune's Weave's DLSS

2026-11-02T02:54:49+00:00

The one-frame blit left 3D edges aliased and shaking: the game jitters its camera every frame for DLSS to accumulate. Fire Emblem: Fortune's Weave's first DLSS pass (also rejected) has the motion vectors (cbuf0+0x290, R16G16) and the frame's jitter (+0x1b0/+0x1b4, in input pixels). Kepler compute keeps them, and the stand-in for the last network pass now draws temporal_upscale.frag: input samples placed where the jitter put them and weighted by distance, blended with the previous result reprojected along the motion vectors (Catmull-Rom) and clipped to the 3x3 neighbourhood in YCoCg. The history is copied from the result right after drawing it, so post-processing the game later applies to its output does not feed back. EDEN_NX2_TEMPORAL_UPSCALE=0 restores the blit.

Skip them while the given file exists (checked every 1024 draws), to time the same scene with and without them in one run.
