Info about amd_acs_x64.dll library used in prepackaged binary?

[oscarbg]

Hi,

just curious the WorkGraphsIvyGenerationSample-v1.0.0 prebuilt binary includes amd_acs_x64.dll library in addition to known amd_ags_x64.dll..
can share more info about this library?..

sample source code seems not using it..
seems the dll has entrypoints:

acsGetRecommendedThreadCountForGameInit
acsGetRecommendedThreadCountForGameplay
acsPrintProcessorInfo

and exe uses:

acsGetRecommendedThreadCountForGameInit
acsPrintProcessorInfo

Hi,
AMD CPU services (ACS) is a library for querying information about the CPU at runtime (e.g. such as the recommended thread count). The library and the pre-built binary are part of the Cauldron framework, which is the framework used for the FidelityFX samples and also this sample.
That's why this DLL is included in the sample binaries, even though the sample code does not directly call any of the DLL's entry points.
