For most Valve Index owners, start at 90 Hz with SteamVR Settings > Video > Render Resolution set to Auto. Keep that combination while you check frame timing in your most demanding game, then raise render resolution for clarity or lower it when frames are missed. Move to 120 or 144 Hz only when the game can sustain those modes; use 80 Hz when you need more GPU headroom. Motion Smoothing is a fallback for inconsistent frame rates, not a guaranteed image-quality upgrade.
What the recommended starting point does—and does not—promise
The Index has a 1440 × 1600 display per eye and supports 80, 90, 120 and 144 Hz refresh rates. Those are hardware capabilities, not universal presets. A flight simulator, a room-scale rhythm game and a visually simple older title can place very different demands on the same computer. The setting that looks sharp and remains stable in one game may cause stutter in another.

Valve’s performance guidance treats Auto render resolution and a 90 Hz refresh rate as starting points. Auto lets SteamVR choose a baseline appropriate to the headset and system; 90 Hz reduces GPU load compared with the higher modes while retaining a responsive image. From there, the useful target is the highest clarity-and-refresh combination that stays stable in the game you are actually playing.

Check compatibility before changing image quality
Confirm that the PC is suitable
Valve lists a GeForce GTX 970 or Radeon RX 480 as minimum graphics hardware for Index and a GeForce GTX 1070 or better as recommended. These are broad requirements, not a promise that every game will run at every refresh rate. A faster GPU gives you more room for supersampled resolution and high-refresh modes, while a CPU-limited title may still miss frames even after a graphics-card upgrade.
- Run Steam’s VR-ready compatibility test before diagnosing settings.
- Install current graphics drivers from your GPU manufacturer before tuning.
- Close overlays, recording tools or background workloads that consume GPU or CPU time while you test.
- Use the same demanding game and repeatable scene for each comparison so that changes are meaningful.
Driver maintenance is a prerequisite check, not a substitute for choosing a refresh rate and resolution your hardware can sustain.
Choose the Index refresh rate first
What each mode is for
| Refresh rate | When to try it | Trade-off |
|---|---|---|
| 80 Hz | When a demanding game needs the lowest GPU load among the Index modes. | More performance headroom, but motion is less fluid than at 90, 120 or 144 Hz. |
| 90 Hz | Balanced baseline for initial setup and mixed game libraries. | Good compromise between smooth motion and GPU demand. |
| 120 Hz | When the target game can sustain the corresponding frame cadence at your chosen resolution. | Smoother motion, with less time available for each frame and therefore greater GPU pressure. |
| 144 Hz | For systems and games that remain stable at the highest Index mode. | Maximum refresh option, but the most demanding on frame delivery. |
Valve specifically recommends trying 90 Hz when GPU load causes lag and notes that reducing refresh rate reduces the load placed on the GPU. Select the refresh rate in SteamVR’s headset or video settings, apply it, and then test the game rather than judging the desktop or a static loading screen.
How to tell whether a mode is sustainable
- Look for missed frames or an unstable frame-time graph while turning, moving through a busy scene, or loading effects.
- Test the area that normally causes trouble, not only an empty room.
- If 120 or 144 Hz produces repeated misses, return to 90 Hz before lowering resolution dramatically.
- If 90 Hz still cannot hold steady, try 80 Hz, then tune resolution and application settings.
A higher refresh rate is beneficial only when frames arrive consistently. A nominally faster mode that repeatedly falls behind can feel worse than a stable lower mode.
Set SteamVR render resolution for clarity
Begin with Auto
- Open SteamVR.
- Open Settings.
- Select Video.
- Set Render Resolution to Auto.
- Launch the game you want to tune and observe frame timing in a demanding scene.
Auto is Valve’s recommended starting point. It does not mean that every game will look equally sharp, nor does it establish a permanent ceiling. It gives you a sensible baseline before you make a deliberate clarity-versus-performance trade.

Raise resolution when headroom exists
If the image looks soft and frame timing remains comfortably stable, increase the render-resolution control in small steps. SteamVR can render above the headset-provided value; Valve describes that extra resolution as supersampled anti-aliasing. It can make distant geometry, text and thin edges easier to resolve, but it also increases GPU work.
After each increase, repeat the same movement and scene test. Stop at the first setting that causes regular frame misses, visible hitching or a large loss of headroom. The highest slider position is not automatically the best setting if it leaves no capacity for a busy scene.

Lower resolution when frames are missed
When the frame-time graph shows sustained overload, reduce render resolution before assuming the headset or game is defective. A modest reduction that restores consistent delivery generally looks better in motion than a sharper setting with repeated stutter. If the game remains unstable at Auto, lower it further for that title or use a per-application override.
Do not treat a number copied from another Index owner as an official target. Valve does not publish one universal percentage because the correct value changes with the GPU, CPU, game and selected refresh rate.
Use per-application profiles for games with different workloads
Global settings are convenient for a mixed library, but one demanding simulator can need a different profile from a lightweight game. Steamworks documents per-game controls for render resolution, minimum refresh rate, half-framerate throttling and Motion Smoothing mode.
Rank #3
- Open SteamVR and go to Settings > Video.
- Open the per-application video controls (the exact label can vary with the SteamVR build).
- Select the game you are configuring.
- Set a lower resolution or refresh-rate requirement for the demanding title, while leaving the global profile at your normal baseline.
- Choose the game’s Motion Smoothing mode deliberately rather than inheriting a setting that was intended for another title.
- Launch the game, test its busiest scene, and adjust one control at a time.
Per-game overrides are especially useful when a title’s performance changes sharply between menus and gameplay. They also prevent a single heavy application from forcing a lower-quality compromise on the rest of your library.
Decide whether Motion Smoothing helps
What it is for
Motion Smoothing is intended as a fallback when a game cannot deliver frames consistently. Valve recommends trying it when frame rates are inconsistent. It can make movement appear more continuous by generating or reusing intermediate frames, but it does not create the same visual information as a fully rendered frame.
Available per-application choices
| Mode | Use it when | What to watch for |
|---|---|---|
| Off | You want every displayed frame to come from the game and the game can remain stable without assistance. | Missed frames may appear as judder or uneven motion. |
| On | You want SteamVR to use Motion Smoothing when performance falls below the selected cadence. | Look for warping around controllers, hands, thin objects or fast-moving scenery. |
| Always-on | You are deliberately prioritizing a consistent synthesized cadence for a particular application. | Artifacts and added latency can be more noticeable because smoothing is used continuously. |
Evaluate Motion Smoothing in the specific game, not in a static environment. A cockpit with readable instruments may reveal ghosting around text; a fast rhythm game may make latency or controller artifacts more obvious. If artifacts distract you, turn it off and lower refresh rate or resolution until the game can render reliably. If the game has irregular spikes that are difficult to eliminate, On may be a practical compromise. Always-on should be a purposeful per-game choice, not a blanket recommendation.
Build a settings profile by priority
Profile A: stable baseline
- Refresh rate: 90 Hz.
- Global render resolution: Auto.
- Motion Smoothing: On only for applications that show inconsistent frame delivery; otherwise Off.
- Use case: first setup, troubleshooting, or a library with varied performance.
This profile gives you a known reference. Change one variable after confirming it is stable.
Profile B: clarity-focused
- Keep 90 Hz if it is stable.
- Increase render resolution gradually above the Auto baseline.
- Leave Motion Smoothing Off when the game remains consistent, so added image artifacts do not mask the effect of the resolution change.
- Use a per-application override for titles that cannot sustain the higher resolution.
Choose this profile when text, distant geometry or fine edges are the main complaint and the frame-time graph shows spare GPU capacity.

Profile C: high-refresh
- Try 120 Hz, then 144 Hz only if the game sustains each selected cadence.
- Keep render resolution at Auto initially; increase it only after high-refresh stability is established.
- Use 80 or 90 Hz for applications that miss frames at the higher modes.
Separating refresh-rate testing from resolution testing prevents two simultaneous increases from making the cause of a performance problem unclear.
Profile D: demanding simulator
- Set a per-application resolution lower than your global profile if necessary.
- Use 80 or 90 Hz when the simulator cannot hold a higher cadence.
- Test Motion Smoothing On for irregular slowdowns, and compare it with a lower-resolution, smoothing-Off profile.
- Keep the profile specific to that simulator so less demanding games retain their normal clarity.
A repeatable tuning procedure
- Prepare the test. Update drivers, close unnecessary background work, and choose a repeatable demanding scene in the game.
- Establish the baseline. Set 90 Hz and Auto render resolution. Record whether the scene is stable and whether the image is acceptably clear.
- Check refresh headroom. Try 120 Hz only if the baseline is stable. If it misses frames, return to 90 Hz; test 144 Hz only after 120 Hz is proven stable.
- Check clarity headroom. At the stable refresh rate, raise render resolution in small increments. Stop when frame timing becomes unreliable.
- Test Motion Smoothing separately. Compare Off and On in the same scene. Keep the option that gives the better combination of motion consistency and acceptable artifacts.
- Save a per-game override. Apply the result to the demanding title rather than lowering the global setting for every game.
- Retest after major changes. A driver update, game patch, graphics setting change or new GPU can alter the balance, so repeat the same scene test instead of assuming the old profile remains optimal.
Diagnose common symptoms
| Symptom | Likely adjustment | Reason |
|---|---|---|
| Sharp image but repeated stutter | Lower render resolution; if needed, lower refresh rate from 144 or 120 to 90 or 80. | The GPU is spending more time rendering than the selected cadence allows. |
| Smooth motion but image is too soft | Keep the stable refresh rate and raise resolution gradually from Auto. | There is clarity headroom without changing motion timing. |
| Artifacts around moving objects with Motion Smoothing | Switch the application to Off and lower resolution or refresh rate until native frame delivery is stable. | Synthesized frames cannot perfectly reconstruct every scene. |
| One game performs badly while others are fine | Create a per-application profile with its own resolution, refresh requirement and Motion Smoothing mode. | Workloads vary by engine and scene; a global compromise is unnecessary. |
| Performance changes between quiet and busy scenes | Use the busiest repeatable scene as the tuning target and leave GPU headroom. | A setting that passes an empty room can fail during effects, crowds or complex geometry. |
| Lowering resolution does not solve the problem | Try a lower refresh rate, check CPU-heavy game settings, update drivers and inspect background workloads. | Not every bottleneck is caused by pixel rendering. |
How hardware affects the ceiling
The GTX 970 or RX 480 minimum listed by Valve is intended to establish basic VR readiness. Valve’s recommended GTX 1070-or-better class gives more room for higher render resolution and refresh rate, but it still does not guarantee a particular game profile. Modern or heavily simulated scenes may remain limited by the CPU, game engine or application settings.
When considering a GPU upgrade, use your current frame-time behavior as the evidence: if lowering render resolution immediately restores stability, additional graphics capacity may let you raise clarity; if the graph remains limited by CPU work, a faster GPU alone may not remove the bottleneck. Treat the hardware tier as guidance rather than a promise of 144 Hz in every title.
Index availability and support
Valve’s current 2026 information says the Index is no longer being produced. Remaining headsets, controllers and accessories are available while supplies last. Existing owners remain supported on Steam and SteamVR. That status matters when planning a replacement setup: availability can change, but it does not alter the refresh-rate, resolution or Motion Smoothing procedure for hardware already in use.

Settings checklist
- Run Steam’s VR-ready compatibility test.
- Update graphics drivers.
- Set the Index to 90 Hz first.
- Set SteamVR Settings > Video > Render Resolution to Auto.
- Test a demanding, repeatable scene and watch frame timing.
- Raise resolution gradually for clarity only when headroom remains.
- Try 120 or 144 Hz only after the game is stable at the lower mode.
- Use 80 Hz when a demanding title needs additional GPU headroom.
- Test Motion Smoothing Off and On in the specific game; use Always-on only for a deliberate per-application profile.
- Save different settings as per-application overrides instead of weakening the global profile.
Why there is no single “best” percentage or refresh rate
Index owners often want a fixed resolution percentage or a universal high-refresh recommendation. Valve does not publish one because the useful setting is conditional: the same headset can be paired with different GPUs, CPUs and games, and each title can change its workload from one scene to the next. The defensible method is to begin with 90 Hz and Auto, then increase one variable until the first repeatable performance problem appears. Keep the highest setting that remains stable in the game you care about most.
