Please describe your issue in as much detail as possible:

Expected result: The minigame (Sleet Fighter II) should run smoothly similar to how Dota 2 matches (or demo) run, with similar FPS

Actual result: Unlike Dota 2 matches (or demo) run, the minigame (Sleet Fighter II) runs with very poor performance and is borderline unplayable (~5 FPS at most, going down to 1-2 FPS big portion of the time)

Steps for reproducing this issue:

1. Make sure game is up to date as of 2024-07-10 20h GMT (has the Crownfall Act 3)
2. Make sure Vulkan shaders are already processed and cached (shader pre-caching is turned on, but they are not processed before launch)
3. Launch game
4. Make sure Vulkan shaders are enabled in game (check in video settings)
5. Make sure Vulkan shaders are used in game and graphics work properly (check in demo game using something intensive in terms of graphics)
6. Open the Crownfall Act 3 map and open up the Sleet Fighter II minigame
