NVIDIA’s G-Sync ULMB 2 aims to minimize motion blur in games


has G-Sync Extremely Low Movement Blur (ULMB) 2, the second technology 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 most recent model presents practically twice as a lot brightness, together with virtually no — the strobing or double-image impact that typically seems when blur discount options are enabled.

Movement readability is basically decided by the monitor’s pixel response time. To enhance issues, NVIDIA is utilizing “full refresh charge 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 % of the time. This lowered the brightness of the display screen.

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

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

What this all boils right down to is NVIDIA with the ability to supply extra brightness and an efficient movement readability of over 1000Hz. When you use a 360Hz monitor with ULMB 2 on, NVIDIA says you will 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 screens, mass-market 1440Hz shows appear fairly a methods off.

NVIDIA supplied some transient demos of ULMB 2 in motion. Within the video beneath, you will see what a motorbike 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 obtainable now as a free replace for suitable 1440p, 360Hz G-Sync screens. Solely two such shows are in the marketplace on the minute, NVIDIA says: the Acer Predator XB273U and the ASUS ROG Swift PG27AQN, each of that are 27-inch screens. The ASUS ROG Swift Professional PG248QP (a 25-inch 1080p, 540Hz show) and the 27-inch AOC AGON AG276QSG G-Sync Monitor are additionally suitable, they usually’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.
