I decided to use zig for my audio experiments and when I switched from cmake to build.zig I experienced a weird problem: my latency measurements are increasing with time, but I don’t ear/see latency actually increasing in real time.
I took two video captures to show you what I mean. The y scale is in nanosecond, used by calling SDL_GetTicksNS().
I suspect this is a related to the ‘wall clock time elapsed’ vs ‘time the thread has actually run’ difference.
SDL_cmake_vs_build-zig.zip
For the record, passing .abi = msvc in build.zig to SDL as well as to my exe/modules/etc… does not change the behaviour.
