Steps How to Enable Vulkan on DOTA 2

1. Go to Steam LIBRARY, select Dota 2, download the “Dota 2 – Vulkan Support” on DLC section. The download size is about 300MB.


2. Right-click Dota 2 then click Properties.




4. Type “-vulkan -vconsole”. Remove other parameters like “-dx9 -dx11 -gl” to avoid conflicts.


Verify if Vulkan is Enabled

1. Run DOTA 2  then open the console and type “vulkan”. If vulkan commands start to show up, it means that Vulkan is now enabled.


2. Press Alt + Tab. Go to “\Steam\steamapps\common\dota 2 beta\game\bin\win64 “. Run “vconsole2.exe”.


3. If you see “Vulkan Extension Enabled: VK_KHR_swapchain” , it means that Vulkan is enabled. The “shaders.cache” error line is expected on AMD cards.


Quick Test

We did a quick test with an Intel i5-3470, AMD Radeon HD7750 1GB, 8GB of RAM on 64-bit Windows 7 with Radeon Crimson 16.7.3 driver. We ran a replay and set DOTA 2 to the Best Looking preset and by typing in “fps_max 500” to console to unlock the fps. Surprisingly, enabling Vulkan will reduce the performance by 11 fps. This is not what Vulkan is supposed to do, but it is just a quick test and we cannot conclude that Vulkan is useless for DOTA 2.
