Low frame rate in Asteroids build with Vulkan API #12

Closed egorodet closed 10 months ago

egorodet commented 10 months ago

Describe the bug "Asteroids" sample built for Vulkan API has significantly lower FPS than for DirectX API in multi-threaded rendering scenario.

Steps To Reproduce Steps to reproduce the behavior:

  1. Run "Asteroids" sample built for DirectX, set scene complexity to 8 (35000 asteroids) => get ~294 FPS
  2. Run "Asteroids" sample built for Vulkan, set scene complexity to 8 (35000 asteroids) => get ~77 FPS

Expected behavior Comparable FPS is expected for DirectX and Vulkan version for the same application with equal parameters.
