240Hz G-SYNC Input Lag Tests

Presenting one of the biggest-ever input lag tests of a 240Hz G-SYNC monitor:

G-SYNC 101: Input Lag & Optimal Settings

Over 5000 input lag measurements averaged into 49 graphs. 42 scenarios, 508 runs, 5080 individual samples, 45 hours, 508 high speed videos, totalling 17.5 gigabytes, taking 2 months to analyze. Recorded across 2 games (Overwatch and CS:GO) and 6 refresh rates, 60Hz, 100Hz, 120Hz, 144Hz, 180Hz, and 240Hz. Even many VSYNC OFF scenarios were tested for comparison, including 1000fps VSYNC OFF. That’s Yes, over five thousand input lag measurements. All averaged to create 49 graphs in this article.

Thank you for your good work, Jorim!




Apple’s new iPad supports 120Hz and Variable Refresh Rates

At WWDC2017 today, Apple announces their new new iPad supports 120Hz and variable refresh rates:

“The Most Advanced Display Featuring ProMotion: The stunning, redesigned Retina® display in iPad Pro features ProMotion, a new technology that delivers refresh rates of up to 120Hz for fluid scrolling, greater responsiveness and smoother motion content. With ProMotion, Apple Pencil is even more responsive with an industry-best, 20-millisecond latency for even more fluid and natural drawing. ProMotion also improves display quality and reduces power consumption by automatically adjusting the display refresh rate to match the movement of the content.”


Adding Variable Refresh Rate Support to HTML 5.2

Variable refresh rate technologies are getting standardized as VESA Adaptive-Sync, HDMI 2.1 VRR, FreeSync, in addition to G-SYNC. Microsoft’s Scorpio Project (the next XBox) is already planned to support variable refresh rate.

Mark of Blur Busters is now an Invited Expert in the W3C Web Platform Working Group.

We currently have github #375 on W3C’s HTML issue-tracking system to add VRR support and VSYNC OFF support to HTML 5.2.

Since web browsers will eventually need to gain VRR support, the HTML 5.2 standard will need to gain preliminary VRR / VSYNC support.
