The studio Grinding Gear Games is calling on Spock to deal with some technical issues in Path of Exile. No, hold on, he is a Vulcan, and the studio Grinding Gear Games now is utilizing Vulkan, a brand new renderer that will offer "more consistent performance than the DirectX 11 one, particularly when under high CPU load." However, the question is, can it do that nifty hand signal?
You can opt into the Vulkan beta by choosing it from the Graphics Options screen under renderer. Of course, it "will not magically make your graphics card perform much better," but, to some extent, it should make for less stuttering and stalling, making "performance a lot more consistent" overall, by that I mean you can farm your Path of Exile Currency more smoothly, or you can use the PoE Currency you bought from eznpc.com more quickly and easily. The key is that it offers Path of Exile full control over how resources are managed and thus letting the game to better utilize your hardware according to its specific requirements.
Actually, Vulkan is a little slower than DirectX 11 at the moment, but it's something that the team hopes to get sorted out by the time the upcoming expansion Path of Exile: Harvest releases this month.
