Vulkan Support For Dota 2 Now Available, Might Boost Performance On Mid-Range Systems
Fans of Dota 2 would know that updates for the game are mostly balance-focused; however, Valve has released a new update for Dota 2 which integrates Vulkan API support into the game. Right now, the update is in beta state, but it is available for everyone.
The API is enabled with a console command, -vulkan, so that it can be easily disabled and enabled. To enable the API in Dota 2, players will require the Vulkan version of Steam overlay.
Now, the question is, what does it mean for gamers? Well ever since this API has been announced, a lot of comparison benchmarks have been done with DirectX 12. No matter how many benchmarks were done, the result was always the same that Vulkan delivers better performance.
By enabling Vulkan in Dota 2, theoretically this should give massive performance boost due to more control over CPU and GPU. If we talk specifically about Dota 2, Valve has not given any specifics about what should and should not be improved.
However, for those who are having some frame rate issues, it is definitely worth a try.
It is important to mention that Valve has advised that players may face stuttering when they play the game for first time after enabling the API, because game assets are being cached. The easiest solution to pass the time while Vulkan caches assets, is to spectate a friend, until the issue is resolved.
