120Hz or 90Hz Refresh Rate: Is the Upgrade Worth It?

What refresh rate means in VR

Refresh rate, measured in hertz (Hz), is the number of times a display updates its image per second. In VR, a higher refresh rate means the headset shows a new frame more often, which can reduce the gap between your movement and what you see. This is important because VR relies on a tight connection between your head motion and the visual response.

A 90Hz display updates 90 times per second, while a 120Hz display updates 120 times per second. The difference in update frequency can affect how smooth motion appears, especially when you turn your head quickly or when objects move fast in the scene. A higher refresh rate can also reduce the perception of flicker, which some people notice at lower rates.

Refresh rate is one of several display specifications that makers state on their product pages. It works together with resolution, lens type, and other factors to determine the overall visual experience. This article focuses on the refresh rate alone and what it means for your buying decision.

90Hz: the standard baseline

Many VR headsets, both standalone and PC VR, list a 90Hz refresh rate as their standard operating mode. For example, the VIVE Focus Vision page states a 90 Hz refresh rate as part of its display specs. This rate has been common since the early days of consumer VR and remains a reliable baseline for most applications.

At 90Hz, the display updates every 11.1 milliseconds. For the majority of VR games and experiences, this rate provides smooth motion that most users find comfortable. It is the default refresh rate for many standalone headsets and for PC VR headsets when connected to a compatible computer.

Some headsets may offer a 90Hz mode as their highest refresh rate, while others may have a 72Hz or 80Hz mode for power saving. When comparing listings, look for the refresh rate stated in the maker's specifications. If a headset does not mention a higher rate, 90Hz is likely its maximum.

120Hz: the smoother upgrade

A 120Hz refresh rate updates the display every 8.3 milliseconds, reducing the time between frames by about 25% compared to 90Hz. This shorter interval can make motion appear more fluid, particularly in fast-moving scenes such as racing games, flight simulators, or action titles where objects pass quickly across your field of view.

The improvement in motion clarity at 120Hz is most noticeable when you move your head rapidly. The reduced frame interval means each frame is closer in time to the previous one, which can lessen the blur or judder that sometimes occurs at lower refresh rates. This is why sim enthusiasts and competitive players often seek PC VR headsets with higher refresh rates.

Not all headsets support 120Hz. When they do, it is usually available only in certain modes: for example, a standalone headset may offer 120Hz in PC VR mode via a link cable, or a PC VR headset may require a powerful graphics card to maintain that rate. Always check the maker's stated details to see if 120Hz is listed and under what conditions it works.

Motion clarity and persistence

Refresh rate is closely related to persistence, which is how long each frame stays lit on the display. Lower persistence can reduce motion blur, and a higher refresh rate allows for shorter persistence without reducing brightness. This combination can improve clarity during head movement.

In general terms, a headset with a 120Hz refresh rate can achieve a lower persistence than one with 90Hz, assuming the same duty cycle. This means moving objects may appear sharper because each frame is displayed for a shorter time. However, the actual persistence value is not always stated on maker pages, so it is not a number you can compare directly across listings. For more on this relationship, see the refresh rate vs persistence article.

The benefit of higher refresh rate for motion clarity is most apparent in content that involves rapid head turns or fast-moving objects. For slower-paced experiences like seated media viewing or puzzle games, the difference between 90Hz and 120Hz may be less noticeable.

How to check a headset's refresh rate

The refresh rate is typically listed in the specifications section of a headset's official product page. Look for a line that says "Refresh Rate" or "Display Refresh Rate" followed by a number in Hz. Some headsets may list multiple refresh rates, such as 90Hz and 120Hz, indicating that the headset can switch between modes.

If the maker page does not state a refresh rate, you can assume the headset uses a standard rate common for its type. For standalone headsets, 72Hz or 90Hz are typical. For PC VR headsets, 90Hz is common, with some models offering 120Hz or even 144Hz. The Valve Index page, for example, does not list a refresh rate on the store page, but the headset is known to support up to 144Hz (this is general knowledge, not from a source page). Always rely on the maker's stated details for the specific model you are considering.

When comparing two headsets, note the refresh rate as one of several stated details. A headset with a higher refresh rate may be preferable for certain uses, but only if your PC or standalone system can consistently deliver frames at that rate. The maker page may also mention the required hardware for achieving the higher rate.

Choosing between 90Hz and 120Hz for your situation

The decision between a 90Hz and a 120Hz headset depends on what you plan to do and what hardware you have. If you play fast-paced games like racing sims, flight sims, or competitive shooters, and you have a PC that can maintain a high frame rate, a premium PC VR headset with 120Hz may offer a noticeable improvement in motion clarity.

For general VR use, including most standalone games, social apps, and media viewing, 90Hz is a solid baseline that works well for the majority of users. Many standalone headsets default to 90Hz to balance performance and battery life. If you are on a budget or your PC is not top-tier, a 90Hz headset is a reliable choice. Check our guide to budget-friendly VR headsets for options.

Also consider that some headsets offer both 90Hz and 120Hz modes, allowing you to choose based on the application. For example, you might use 120Hz for a racing game and switch to 90Hz for a longer session to save battery. Check the maker's page to see if the headset supports multiple refresh rates and how to switch between them.

Ultimately, the refresh rate is one factor among many. Resolution, field of view, tracking, and comfort also play important roles. Use the best VR headset guide to compare headsets on stated details and find the best match for your needs.

Questions

What is the difference between 90Hz and 120Hz in VR?

90Hz updates the display 90 times per second, while 120Hz updates 120 times per second. The higher rate reduces the time between frames, which can make motion appear smoother and reduce perceived flicker, especially during fast head movements.

Is 120Hz always better than 90Hz?

Not necessarily. A higher refresh rate requires more processing power from the headset or PC. If your system cannot consistently deliver frames at 120Hz, you may experience stuttering or reprojection, which can be worse than a steady 90Hz. The benefit depends on the content and your hardware.

Can I use a 120Hz headset at 90Hz?

Many headsets that support 120Hz also offer a 90Hz mode. You can often switch between refresh rates in the headset settings or via the connected PC. This allows you to choose the rate that best matches the application and your system's performance.

Do all VR headsets list their refresh rate?

Most maker pages include the refresh rate in the specifications. If it is not listed, you can assume a standard rate such as 90Hz for PC VR headsets or 72Hz–90Hz for standalone headsets. Always check the official product page for the most accurate information.

Does refresh rate affect battery life on standalone headsets?

Yes, a higher refresh rate consumes more power because the display and processor work harder. Standalone headsets may default to 90Hz to balance performance and battery life. Some headsets allow you to lower the refresh rate to extend playtime.

What refresh rate does the PlayStation VR2 use?

The PlayStation VR2 supports both 90Hz and 120Hz modes, depending on the game. The maker page does not specify a single rate, but the headset can switch between them to match the content. Check the game's requirements for the expected refresh rate.

Can I notice the difference between 90Hz and 120Hz?

Many people notice a difference, especially in fast-moving scenes. The improvement in motion clarity and reduced flicker can be subtle or significant depending on the individual and the content. If you are sensitive to motion, a higher refresh rate may be more comfortable.
