NVIDIA has revealed G-Sync Ultra Low Motion Blur (ULMB) 2, the second generation of tech it designed to minimize motion blur in competitive games. Compared with ULMB, which it released in 2015, the company says the latest version offers nearly twice as much brightness, along with almost no crosstalk — the strobing or double-image effect that sometimes appears when blur reduction features are enabled.

Motion clarity is largely determined by the monitor’s pixel response time. To improve matters, NVIDIA is using “full refresh rate backlight strobing,” which builds on the backlight strobing technique from the original ULMB. Although the previous version of the tech improved motion clarity for many, it needed to switch off the monitor’s backlight 75 percent of the time. This reduced the brightness of the screen.

With ULMB 2, NVIDIA is able to match the display’s refresh rate when it turns the backlight on and off. The aim is to only turn the backlight on when pixels are at the correct color value for each frame. This mitigates crosstalk, as you shouldn’t see pixels when they’re transitioning to the accurate color.

This approach wasn’t really possible with the slower pixel refresh rates of older monitors. ULMB 2 is able to run at the full refresh rate of current displays. On a 360Hz display, each backlight strobe happens every 2.7 milliseconds — a rate that’s imperceptible to the human eye.

What this all boils down to is NVIDIA being able to offer more brightness and an effective motion clarity of over 1000Hz. If you use a 360Hz monitor with ULMB 2 on, NVIDIA says you’ll get an effective motion clarity of 1440Hz. The company claims that, without ULMB 2, you’d need a monitor that’s capable of 1440Hz to get equivalent motion clarity. Given that we’ve only recentlystarted seeing 500Hz monitors, mass-market 1440Hz displays seem quite a ways off.

NVIDIA offered some brief demos of ULMB 2 in action. In the video below, you’ll see what a motorcycle pursuit sequence looks like in slow-motion at 360 frames per second with the feature both off and on.

ULMB 2 is available now as a free update for compatible 1440p, 360Hz G-Sync monitors. Only two such displays are on the market at the minute, NVIDIA says: the Acer Predator XB273U and the ASUS ROG Swift PG27AQN, both of which are 27-inch monitors. The ASUS ROG Swift Pro PG248QP (a 25-inch 1080p, 540Hz display) and the 27-inch AOC AGON AG276QSG G-Sync Monitor are also compatible, and they’ll be available soon.

NVIDIA announced ULMB 2 alongside some AI developments at Computex. The company is developing a supercomputer that’s designed to help companies build generative AI models. It also showed off tech that will enable players to use their microphones and have somewhat realistic conversations with in-game characters.

ARM just sent a not-so-subtle warning to Android phone makers still hanging on to 32-bit technology. The company has introduced its first lineup of CPU core designs that are exclusively 64-bit — unlike last year, there’s no legacy tech for vendors to use. The Cortex-X4, Cortex-A720 and Cortex-A520 don’t always represent major leaps in performance, but they’re likely to set the pace for Android in the near future.

The Cortex-X4, like the X3, is a performance core aimed at flagship phones. Its updated architecture delivers a 15 percent claimed higher performance, but uses 40 percent less power than its predecessor. That translates to faster app launches and a more responsive interface, according to ARM. We also wouldn’t be surprised if this led to improved battery life in games and other intensive tasks.

Meanwhile, the Cortex-A720 is a sequel to the A715 “middle” core that handles most computing chores. While it is faster, the focus is on longevity. ARM claims the A720 is over 20 percent more power efficient than last year’s design. Chipmakers can even use a smaller ‘entry’ version to cut costs or shrink their hardware.

We wouldn’t discount the Cortex-A520 efficiency core. While it’s ultimately meant for background processing and other low-demand duties, it’s reportedly 22 percent more efficient than the A510 it’s replacing while managing eight percent better performance. Your phone might last longer even if you aren’t a heavy-duty user.

Yes, ARM is also paying attention to graphics performance. It’s simultaneously launching Immortalis-G720, Mali-G720 and Mali-G620 GPU designs that again offer more performance with a reduced power draw. They notably introduce a deferred vertex shading (DVS) pipeline that uses much less bandwidth (33 percent less in the demanding Genshin Impact), leaving room for more complex scenes and HDR visuals. The Immortalis is said to offer an average 15 percent jump in performance over its predecessor, even as it’s 15 percent more efficient. It supports 10 or more cores, while the Mali-G720 supports six to nine cores. The G620 is the budget offering with five cores or less.

ARM hasn’t named customers. As virtually the entire mobile industry is built around ARM, though, we’d expect Qualcomm, MediaTek and others to use the new Cortex designs as starting points for their next system-on-chip models. Whether or not Apple uses it isn’t clear. Although Apple uses ARM, it hasn’t yet made the leap to the newer ARMV9 architecture.

It’s safe to say this will influence the Android market, at least. While Apple cut off support for 32-bit hardware and apps with iOS 11’s release in 2017, AnandTechnotes that Android has moved relatively slowly, with Chinese brands like Oppo and Xiaomi holding on to 32-bit capable SoCs for a particularly long time. The new ARM range effectively pushes those companies to upgrade — either they use pure 64-bit SoCs or risk being left behind.
