In patch 3.10.2 we got something we did not even hope for. The new Vulkan Renderer is now in Beta version on the live servers and you can select it in game instead of DirectX 11. The Vulkan Renderer allows for much less flat lines when it comes to screen freezes and FPS drops, essentially allowing you to have much more stable gaming experience. Compared to the previous “open a legion and wait 5 seconds until your PC unfreezes” you can now actually play the game.
You can see a “test-drive” of the new Vulkan Renderer and then comparison between it and DirectX 11 in the same in-game environment in this video by EmpyrianGaming.
