NVIDIA’s G-Sync ULMB 2 goals to attenuate movement blur in video games

has G-Sync Extremely Low Movement Blur (ULMB) 2, the second era of tech it designed to attenuate movement blur in aggressive video games. In contrast with ULMB, which it launched in 2015, the corporate says the newest model affords almost twice as a lot brightness, together with nearly no — the strobing or double-image impact that typically seems when blur discount options are enabled.

Movement readability is essentially decided by the monitor’s pixel response time. To enhance issues, NVIDIA is utilizing “full refresh fee backlight strobing,” which builds on the backlight strobing approach from the unique ULMB. Though the earlier model of the tech improved movement readability for a lot of, it wanted to modify off the monitor’s backlight 75 p.c of the time. This lowered the brightness of the display.

With ULMB 2, NVIDIA is ready to match the show’s refresh fee when it turns the backlight on and off. The goal is to solely flip the backlight on when pixels are on the appropriate colour worth for every body. This mitigates crosstalk, as you should not see pixels once they’re transitioning to the correct colour.

This method with the slower pixel refresh charges of older displays. ULMB 2 is ready to run on the full refresh fee of present shows. On a 360Hz show, every backlight strobe occurs each 2.7 milliseconds — a fee that is imperceptible to the human eye.

What this all boils all the way down to is NVIDIA having the ability to supply extra brightness and an efficient movement readability of over 1000Hz. In case you use a 360Hz monitor with ULMB 2 on, NVIDIA says you may get an efficient movement readability of 1440Hz. The corporate claims that, with out ULMB 2, you’d want a monitor that is able to 1440Hz to get equal movement readability. On condition that we have 500Hz displays, mass-market 1440Hz shows appear fairly a methods off.

NVIDIA provided some transient demos of ULMB 2 in motion. Within the video beneath, you may see what a bike pursuit sequence appears to be like like in slow-motion at 360 frames per second with the function each on and off.

ULMB 2 is accessible now as a free replace for appropriate 1440p, 360Hz G-Sync displays. Solely two such shows are available on the market on the minute, NVIDIA says: the Acer Predator XB273U and the ASUS ROG Swift PG27AQN, each of that are 27-inch displays. The ASUS ROG Swift Professional PG248QP (a 25-inch 1080p, 540Hz show) and the 27-inch AOC AGON AG276QSG G-Sync Monitor are additionally appropriate, and so they’ll be out there quickly.

NVIDIA introduced ULMB 2 alongside some AI developments at Computex. The corporate is that is designed to assist firms construct generative AI fashions. It additionally confirmed off tech that may allow gamers to make use of their microphones and with in-game characters.
