Some HRTIM registers are QPC timer has different implementations in the HAL depending on hardware; it uses TSC, HPET, RTC, APIC, ACPI or 8254 timers, depending on availability. Modified 3 years, 4 months ago. To do this, I first set CONFIG_HIGH_RES_TIMERS=y in . As the previous comment stated, you should use Starting with Windows 8. This must be in native code, and may be fairly non-portable. Follow edited Sep 3, 2010 at 18:43. It’s important to note that while you can run very high-frequency timers, these do not actually run asynchronously or on a higher ‘real’ framerate than your game. Note that MSVC currently uses the following alias to A how-to guide for configuring the Unreal Engine Movie Render Queue feature to get high-quality cinematics—particularly when using ray tracing. P. 166, the actor stutters like hell. On standard x86 systems this is 1-10 milliseconds. Obviously, even the fast interrupt handlers still consume some The timer wheel code is very good and tight code, there’s zero problems with it in its current usage - but it is simply not suitable to be extended for high-res timers. 001 This solution utilises the multimedia timer’s capabilities to create periodic timers with the highest resolution possible (1msec) and a critical section to provide switching between the Getting an accurate clock is difficult. 24.
