Assess Vulkan's impact on your gameplay with a comparison. Start a match or load a custom map, then:

  1. Press F3 to open the in-game statistics overlay.
  2. Press F11 to minimize the game.
  3. Exit the game and return to Steam.
  4. Disable the -appalapi vulkan command in the launch options.
  5. Reload the game and repeat the test without Vulkan.

Compare the frame rates and graphical performance between the two tests to judge Vulkan's impact.

While Vulkan automates many rendering tasks, certain features can optimize performance.

Disable Ray Tracing and DLSS

While these features offer impressive visuals, they significantly impact performance. Disabling these in the game's graphics settings can free up resources, improving frame rates.

Adjust AA, AF, and Resolution

Tweak Anti-Aliasing (AA), Anti-Aliasing (AF), and resolution settings to balance visual detail and performance. Start with medium settings, testing and adjusting until you find the sweet spot for your hardware.

Since Vulkan is more hardware-taxing, maintaining a stable frame rate might require closer monitoring and tweaking. But with the right adjustments, expect a smoother, more dynamic Rainbow Six Siege experience. Happy raiding!
