Phoronix: Vulkan 1.3.242 Released With New NVIDIA Low-Latency Extension

The Vulkan 1.3.242 spec is now available with a handful of clarifications and fixes to the existing text as well as introducing the new VK_NV_low_latency extension...

What a bad name for an extension... "VK_NV_low_latency". I guess after few years we will have "VK_NV_low_latency_new" or "VK_NV_lower_latency"

If you'd have read the pull request or even part of the article you'd know that it's not a true/false operation but an API specifically for querying different properties, such that it's extensible to new APIs or even other vendors.

Reflex display requirement is only for input lag measurements with mouse connected to such a display. Latency reduction happens with any display. My uneducated guess is it's the driver telling in-game limiters how to limit dynamically based on whatever required stats, so there never is any CPU prerender.

Thanks for reminding me that it is not enough to read the title and comments. Found guilty... on other hand... still I don't think that word _low_ in the API is good - what is more this extension does not explain which latency.

=== Description

This extension adds the slink:VkQueryLowLatencySupportNV structure, a
structure used to query support for NVIDIA Reflex.

Obvious!

It's also possible to enable Reflex using SpecialK[0] for almost any (DirectX) game. Together with the intelligent frame limiter you can get close to 0 frame latency with vsync enabled. It also works in wine/proton but I can't say how well or how necessary it is. On Windows it's a huge difference at least.

And there even is a vendor agnostic vendor agnostic alternative to Nvidia Reflex, that could definitely use some more love

This is the way supermen are doing it:
1. Comment!
2. Read the title
3. Comment again!
4. Discuss as much as you can.
But never read the article!
