Your system information

Please describe your issue in as much detail as possible:

Hello. I have such a problem. I launched Dota using Vulkan Api. And here the problems begin. The frame rate is unstable. Constantly jumps even in the main menu 60-90. But these are little things. When I start searching for a game and finds it for me, I click "accept." And when loading the character selection screen, I sometimes have a graphic frieze. That is, I hear the commentator’s voice in the menu, the character selection order, but I don’t see anything (the picture froze) and I can’t choose. You have to restart Dota. And very lucky if they do not count me as if I left the game. Recently it was. They gave me a low priority and now I need to play 3 games (I already won 2). In addition, if the game starts normally, then the frame rate of the game is very unstable. Often drops to 30-45, and indeed a lower frequency than OpenGL. On OpenGL rendering, everything is going stably. There are no such problems. And by the way, after the game it is on the Vulkan render, my system slows down. Please refine this render and fix it. thank

Steps for reproducing this issue:

  1. Start the game
  2. Find a game and try to choose a character
  3. Frieze or in-game very unstable FPS

vulkan is much more gentle on the CPU than opengl... then, sometimes, the linux cpufreq governor will decrease the "CPU frequency" while using the vulkan backend but not while user the GL backend. Try to set the cpufreq governors for all your cores to "performance" (google) It will help to get more FPS for sure, but the source of your pb may be totally something else.
