lunarG, the company that works with Valve on vulkan has released its VulkanSDK so now is the time to see what will happen. Arma3 could use some GPU love as well as being multithreaded and also makes the engine more portable since you don't need to rewrite the rendering engine.
@Kronzky: in a previous version we could get items such as GPS, medpack and etc... the latest version doesn't offer those. Is there any way to reimplement those? also is it possible to add silencers, scope?
Cheers
