[PATCH v2 0/4] MR9915: mmedvapi: Device name changes.
by Bernhard Kölbl Jan. 20, 2026

Jan. 20, 2026

The test in the last commit would still need an implementation, which turned out to be more complicated than the possible benefits. -- v2: mmdevapi/tests: Test for DEVPKEY_Device_FriendlyName in the registry. https://gitlab.winehq.org/wine/wine/-/merge_requests/9915

The bottleneck might be the indirect calls to `get` and `put` or the index calculation code in the outer loop. I haven't tried myself but I suspect this is where the computational complexity of the current filter comes back to bite us. As much as you can make the arithmetic and data accesses faster, it's always going to be ~60 multiplications and additions fetching data from 2 "large" arrays per sample for a FIR / sinc filter vs one order of magnitude fewer arithmetic operations, accessing a single large input data array for a cubic one. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9588#note_127395

[PATCH 0/28] MR9928: Draft: dsound: Speed up resampling.
by Anton Baskanov (＠baskanov) Jan. 20, 2026

Jan. 20, 2026

This implements a number of optimizations, in particular: - Swapping around the resampling loops in case of downsampling, allowing the FIR step to stay fixed regardless of the resampling ratio. - Rearranging the FIR array elements to make the access sequential. - Adding SSE versions of the resampling functions. Together, these amount to more than a 5x reduction of `cp_fields_resample` execution time. The quality of the resampling should be the same, or even improve slightly, due to a more precise `rem` calculation and removal of the FIR step rounding, although I haven't yet conducted any measurements. -- This merge request has too many patches to be relayed via email.

Here are my changes: !9928 > When I wrote this MR I felt like the current resampler might be hopelessly too complex for realtime resampling of 100+ sound buffers (which is what Fallout 3 and New Vegas can end up with on occasion). That's interesting. My changes seem to be enough to fix the crackling in Star Wolves 3, which also creates 100+ buffers. Tested on a laptop with AMD Ryzen 5 3500U with the frequency reduced to 1400 GHz. I also tried to add AVX+FMA3 versions of the resampling functions, but I'm getting diminishing returns. The bottleneck might be the indirect calls to `get` and `put` or the index calculation code in the outer loop. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/9588#note_127381
