Phoronix: NVIDIA Introduces New Low-Latency Vulkan Extension For Gaming

Vulkan 1.3.266 was published a few days ago with a handful of fixes and two new extensions. One of those extensions, VK_NV_low_latency2 is quite interesting...

For AMD GPU users here, you can try running really recent (git) gamescope from tty with immediate flips flag:

gamescope -w 1920 -h 1080 -W 1920 -H 1080 --immediate-flips -- steam -gamepadui

This should run Steam's big picture at 1920x1080 with immediate flips support enabled. If you have FreeSync capable display, you can also append --adaptive-sync to gamescope's parameters.
Gamescope has a really great design around input latency.
Also if you're CS2 or Dota 2 player, you can add -vulkan_enable_google_display_timing to the game's launch options. This will show Nvidia Reflex in the graphics settings, which will reduce input lag even further.

Does this allow achieving Reflex-like latency without having to link against its SDK? This may be a great thing for open source apps if this is the case.

Wish nvidia would support the below and allow FG under Linux with them.

Would be interesting to see if RADV could support the extension as well, as it seems this updated version of the extension is designed to stand on its own rather than just being a way to tie into Reflex SDK.

Finally an extension that addresses the increased input lag users experience with higher performance graphics cards when their monitor can't keep up with the card!
