Gaming DirectX or OPENGL?

well when this Vulkan with Open GL does hit market, won't it install with a new Nvidia driver update via Nvidia. But I should think they wouldn't let out without it being cutting edge for the OpenGL side of things.

the last 3 Driver releases from Nvidia have Vulkan already installed as part of the driver set.

DirectX, particularly 12. OpenGL has always seemed to perform less-than expected.

True; Vulkan does NOT require DX12, despite feature commonality.  (nVidia's Fermi GPUs, for example, support Vulkan natively, but do not support DX12 at all.  In fact, the Vulkan feature set goes back surprisingly far merely on nVidia GPUs - in addition to Fermi, it also covers Tesla - which is JUST coming to desktops and portables (as GT710/730), and is more known on Android and in Chromebooks (as opposed to Windows or Linux). Speaking of Linux, Vulkan is, in fact, an optional feature in Wayland (and Canonical's Mir), but not in X - yet.)

 

For that very reason, Vulkan - not DX12 - can be a point of comparison between otherwise-dissimilar GPUs because it's a common API.  (That is, in fact, why Vulkan has been used when comparing GTX980 and GTX1080.)

Fun fact. The new Doom game uses id tech 6 engine which is opengl.

iD has been the only company still giving a ###### for ages.  Vulkan might change the landscape considerably, but iD using OpenGL again should be a surprise to nobody.
