--- Comment #1 from Anastasius Focht focht@gmx.net --- Hello folks,
another valuable resource of improving/fixing Wine on ARM64 is the Chrome browser port to Windows 10 ARM64 platform that is currently underway and going to continue for some months.
I'm following various Chromium and LLVM/Clang pull requests related to Win10 ARM64 porting activities.

--- snip --- #if defined(_M_ARM64)
#define ReadCycleCounter() _ReadStatusReg(ARM64_PMCCNTR_EL0)
#else // X86 or X64
#define ReadCycleCounter() __rdtsc()
#endif --- snip ---
which backs my current analysis/conclusions.
