Vulkan question: 385.69 Nvidia Driver "Vulkan Libraries" not installed / listed ?!

[Slayer Seraph]

Hey I used DDU to wipe my drivers and installed Nvidia's Latest Driver: 385.69.
I picked custom install and only installed the driver + HD Audio Driver.
(Unticking physx, 3D and Experience)
I checked "Programs and Features" in control panel - and I don't see a program called: "Vulkan libraries" in the bottom of the list.

Could it be that Nvidia had removed "Vulkan Libraries..." and perhaps merged it into the Nvidia Driver in a built in fashion?

Can you please check if you have such am item called Vulkan Libraries?

Thanks.

i didnt have a option to disable it like with opengl too ;)
but i install only the core drivers and the physix drivers. i think u need the audio drivers only if u use integrated speakers in ur monitor

There isn't a Vulkan libraries. Just install the driver but you should include physx.

Why should I include Physx?
Almost no game today, that I am aware of, uses Physx.
Doom doesn't use it either.
So I really think there is no reason to install it anymore -unless I'm missing something?

Again- why use Physx? What games that you play actually take advantage of that?

EDIT:
Ok seems like some modern games actually use Physx in a way. The Witcher 3 is the only game in the list that I actually play.
Still the list is very minimal:

About HD Audio Drivers:
No - HD Audio Drivers are used mainly for something else entirely.
What they are primary used for- is sending Audio (as well as video) over HDMI - when connecting the GPU to an AV Receiver or TV - by HDMI cable from 1 HDMI port to another.

I actually make really good use of them do I definitely need them 100%.

I have my GPU connected to my AV Receiver- sending both surround 5.1 audio to the Speaker setup and video to the TV.

From my experience I get the best audio with the HDMI cable connected to the GPU.

Update: I asked the topic question over GeForce forums too- someone replied that the latest drivers excluded "Vulkan RT Library" from the uninstall / programs list. The driver is built into Nvidia basically:

Issues and updates:
-Vulkan installer removed from Add/Remove Programs. You may verify which Vulkan runtime is installed, you may do so by opening a Run window and typing "vulkaninfo" into the Open field.

This is not a driver issue, the vulkanRT installer itself is not creating uninstall information even when installed from SDK

You have quite a few titles that use PhysX - and even more that use Gameworks, which require the PhysX libraries installed to work properly.

As to Doom and PhysX, while not officially stated, changing PhysX settings in the nVidia drivers does resolve some issues, so it does have an impact on the game.

Since the PhysX libraries don't create additional overhead, there is no reason not to install them.

Edit: I don't know why, but nVidia's list of PhysX titles is woefully incomplete.

Thanks for the info.
I re-cleaned the drivers using DDU again and this time clean installed: Nvidia Driver + HD Audio Driver + PhysX Driver.
I guess there's no harm in keeping it, and games might use it in various big or subtle ways too, so might as well.

What kind of changes tothe PhysX for Doom? And what issues are you talking about exactly? Is this something common, that requires tweaking?

If you aren't getting black screen crashes, you don't need to change anything with PhysX in Doom.

I don't know if it actually does anything, but it has an impact on stability.
