Configuring lsfg-vk
Pacing Modes

Pacing Modes

The pacing mode determines how lsfg-vk synchronizes frame generation with the application’s render loop.

  • Vsync / vsync: No frame pacing. Frames are generated and presented as soon as they are ready. This approach requires Vsync to be enabled in the game settings, otherwise frames will be skipped.
  • There are no other pacing modes available at this time.

Background

Traditionally, lsfg-vk did not have frame pacing and would present frames to the screen as soon as they are generated. This approach is flawed, because frames are generated and presented much quicker than your screen refreshes, causing frames to be skipped.

This effect is countered by force-enabling Vsync, as Vulkan will now only process one image per Vblank. Even though this works, it is not ideal as frame pacing only properly works if the target refresh rate is the exact monitor refresh rate. Additionally Vsync introduces latency and may cause issues with VRR in this configuration.
