Error code ERR_SYS_TIMER_RDTSC screams your CPU lacks the rdtsc instruction. But you’re on a Ryzen 9?!

Fix:

  • Disable overclocks: Even if stable elsewhere, GTA’s janky timer code can’t handle it.

  • BIOS update: Some X570 boards (looking at you, Aorus) need firmware tweaks for Ryzen compatibility.
