An article on the NVIDIA Website announces the launch of NVIDIA Reflex support for Overwatch, Blizzard's competitive hero shooter. The article notes that Rust and Ghostrunner will soon get Reflex support (they already appear on the list of Reflex-compatible products), and that further latency reductions will soon come to both Fortnite and Valorant. Here's a separate article on how Reflex support in Overwatch cuts system latency in half and a video showing this in action. Here's more on Reflex improvements:

NVIDIA Reflex Keeps Getting Better
Other improvements to NVIDIA Reflex include:

• A new enhancement to ‘Boost’ mode that can reduce latency in certain CPU-bound scenarios.
  • Fortnite has implemented the optimization and players can see up to a 15% latency reduction in these CPU bound scenarios.
  • Valorant will be releasing their update in the next patch. Early testing is showing a 10-15% improvement in CPU-bound scenarios.

• Introduction of four new Reflex Latency Analyzer-compatible mice, including:
  • ASUS ROG KERIS WIRED
