Introduction to G-Sync Pulsar
Nvidia’s G-Sync Pulsar is a significant enhancement of the company’s variable refresh rate (VRR) technology, promising both smoother motion and more visual clarity. First teased at CES 2024, G-Sync Pulsar has been highly anticipated by gamers and tech enthusiasts alike. The technology claims to deliver a gaming image with the smoothness equivalent of a 1,000Hz screen, making it a potentially explosive feature for competitive gamers. With the release of G-Sync Pulsar-enabled gaming monitors at CES 2026, we can finally put this technology to the test.
What is G-Sync Pulsar?
G-Sync Pulsar is an evolution of variable refresh rate technology. Traditional VRR dynamically adjusts the display’s refresh rate to match the GPU’s frame rate at any given moment, effectively eliminating screen tearing and stutter. However, VRR doesn’t eliminate display motion blur, which is caused by both slow LCD transitions and the persistence of an image on your retina as it tracks on-screen movement. G-Sync Pulsar overcomes this limitation by combining three techniques: Rolling Scan, Compensation Pulse, and G-Sync Variable Overdrive. Rolling Scan allows pixels to achieve their correct values before being backlit, resulting in four times the effective motion clarity. Compensation Pulse briefly pulses each screen segment to compensate for the variation in frame rate, pushing the flicker outside human visual perception. G-Sync Variable Overdrive adjusts the pulses based on the predicted time the next frame will be displayed.
Testing G-Sync Pulsar
To test G-Sync Pulsar, we used a cutting-edge desktop PC with an Nvidia GeForce RTX 5090 graphics card, an AMD Ryzen 9 9950X flagship CPU, and 32GB of DDR5 RAM. We connected the Asus ROG Strix XG27AQNGV, one of the first gaming monitors to feature G-Sync Pulsar, to these components. The monitor has a 2,560-by-1,440-pixel resolution and a 360Hz native refresh rate. We enabled HDR in Windows and the games we tested, as well as ray tracing, where the game supported it. We then examined three different games to see if we could identify any significant improvements with the new Pulsar feature activated. The games included Anno 117: Vox Romana, Marvel Rivals, and Overwatch 2. In each game, we noticed improved motion clarity, particularly in scenes with fast-moving objects or text.
Is G-Sync Pulsar Worth It?
While the improvements offered by G-Sync Pulsar are minor in the grand scheme of things, they are still noticeable, particularly for esports players. The technology eliminates the need to choose between smooth variable refresh rates and improved motion clarity, making it a valuable feature for competitive gamers. However, casual gamers may not appreciate the difference as much. We measured the performance of G-Sync Pulsar using the Nvidia Latency and Display Analysis Tool (LDAT) and observed a significant improvement in motion clarity. The LDAT Display Test includes a Textured Stripe setting that generates a useful scrolling test pattern, which lets us easily evaluate a display’s motion performance characteristics. We also performed a latency test on Counter-Strike 2, where we noted an average of 7.7ms (milliseconds) of latency after firing 100 shots – an excellent result for an esports monitor.
Conclusion
G-Sync Pulsar is a noteworthy evolution of G-Sync that only hard-core gamers are likely to appreciate. The technology combines the benefits of VRR and ULMB 2 to eliminate the need to choose between smooth variable refresh rates and improved motion clarity. While the improvements may be minor for casual gamers, they are significant for esports professionals. With the release of G-Sync Pulsar-enabled gaming monitors, gamers can finally experience the benefits of this technology for themselves. The Asus ROG Strix XG27AQNGV, Acer Predator XB273U F5, and MSI MPG 272QRF X36 are just a few examples of monitors that support G-Sync Pulsar, and they are available for purchase starting at $599.
