ASTC: decode and re-compress to BC1/BC3 on the GPU; texture cache budget

2026-10-29T00:43:01+00:00

- accelerate_astc=Gpu with astc_recompression=Bc1/Bc3 now decodes ASTC with the GPU decoder into a temporary RGBA8 image (dedicated memory, freed once the GPU is past it) and compresses it with a new compute shader (bc_encoder.comp: bounding-box endpoints along the colours' covariance, inset 1/16, nearest palette entry; BC3 alpha ramp; BC1 punch-through), then copies the blocks into the image. No CPU decode, so streamed textures are ready the frame they are first used instead of showing placeholders for seconds; the decode pass no longer waits for the GPU on this path. - The CPU path (CpuAsynchronous) fills a new image with zero blocks before its first decode instead of showing stale VRAM, and the transcode pool is a quarter of the hardware threads. - Switch 2 titles: collector thresholds near the device budget, re-read every 60 frames from VK_EXT_memory_budget (another game shrank it from 7.0 to 5.4 GB). - EDEN_NX2_HIDE_WINDOW=0 now leaves the window visible.

ASTC transcode pool: an eighth of the hardware threads (at least 2)

With half (8 on a Ryzen 7 8845HS), re-compressing streamed ASTC textures to BC3 took ~3.5 cores away from the six emulated cores and the GPU thread. Title 1 attract loop, 65-150 s: 8 threads 16.0 fps, 4 threads 12.6, 2 threads 18.9 (scene noise is large). EDEN_NX2_TRANSCODE_THREADS overrides.

[core, gpu, threads] Multithreading refactor (#4254)

2026-08-08T02:39:47+00:00

This insufferable work tries to cover some holes on previous threading implementation from yuzu's team, starting with Windows and Linux reordering of priorities (NICE), reworks previous Android's threading and cpu affinity with adpf, adjust emulated clocks/gpu for better "accuracy" with their work, bumps android minSDK for all flavors, legacy will now work with AP 29 to cover A10 - A12, standard will reach A13 as base and finally the optimized build will come with API 35, mostly targeted on devices with A15 support and newer, NDK and AGP wasn't upgraded yet. The performance cost efficiency have been improved based on device power configuration; preventing overheating if certain devices tended to fall into NICE0 (not allocated threads priority, all task ran with higher priority, 11 tasks running within the limited 2 - 7 threads available on the most common configuration 1x3x4 or 1x4x3).

[cmake] enable clang-cl and WoA builds (#348)

2025-09-09T18:47:49+00:00

Compilation and CMake fixes for both Windows on ARM and clang-cl, meaning Windows can now be built on both MSVC and clang on both amd64 and aarch64. Compiling on clang is *dramatically* faster so this should be useful for CI.
