I have encountered a situation where tracy fails on (bit old) x64 laptop because RDTSCP instruction is not available. It appears that we can not assume RDTSCP presence on x86-64 platforms.

This is both by design and no longer an issue. Due to unrelated reasons, Tracy v0.6 uses RDTSC instead of RDTSCP. If that is still a problem (as it apparently can be, in cloud environment), you can use the TRACY_TIMER_QPC macro on master branch to use low-resolution system timer.
