Limit frame rate in games for smoother performance and less power

For most games, capping is the better choice. A fixed ceiling helps you reach a steady level of performance and hold it there, as long as your hardware can keep up, and it makes tearing less likely. Because the GPU isn’t racing flat out, it also runs cooler and quieter and uses less power overall.

Screen tearing is worth understanding. It happens when your graphics card sends a fresh frame while the monitor is still in the middle of drawing the last one. Parts of two different frames end up on screen at once, which shows up as jagged horizontal lines whenever the picture moves. It’s easy to spot in fast games and hard to ignore once you notice it.

A cap can’t fix everything. If your GPU regularly drops well below the number you set, you’ll still see uneven performance. The cap is a ceiling, not a floor.

A frame cap matters most on a variable refresh rate (VRR) monitor. VRR screens, sold under names like NVIDIA G-Sync and AMD FreeSync, adjust their refresh rate on the fly to match whatever your graphics card is producing. That works inside a set window, which generally begins at 48 fps and ends at your display’s top refresh rate.

The trouble starts when a game shoots past that top limit. A cap keeps the action inside the VRR window, so the frame rate never slams into the ceiling, and that trims latency slightly. Combined with V-Sync, it should mean you don’t see tearing at all.

You also don’t need to worry much about small dips. Because G-Sync and FreeSync keep the screen in step with the GPU, a drop from 120 fps to 110 fps can be close to invisible on a VRR display.

One recent example shows how much these settings depend on drivers. In October, NVIDIA released hotfix driver 617.70 after owners of 360Hz G-Sync Pulsar monitors found their games capping near 320 FPS, short of what the panel can show. NVIDIA said the problem was a timing error in the driver rather than a lack of GPU power, and recommended that people without the bug wait for the next fully certified driver.

The rule of thumb is simple: with V-Sync on, set your cap three or four frames below your monitor’s maximum refresh rate. That works out to:

• 57 fps for a 60Hz screen
• 117 fps for a 120Hz screen
• 237 fps for a 240Hz screen

Will you miss those few frames? Almost certainly not. The gap between 57 and 60 fps, or between 237 and 240, is too small for most people to notice. What you will notice is a cleaner, tear-free picture, provided your graphics card can hold the cap without falling below it.

For everyday players, the most noticeable gains are quieter fans and a cooler machine. A GPU running below its limit draws less power, which adds up over long sessions. When AMD introduced its Radeon Chill feature in 2016, which manages frame rates to save energy, the company claimed it could cut power use by as much as 31 percent and temperatures by up to 13 percent.

The trade-off is V-Sync. It locks the frame rate so it can’t go above your screen’s refresh rate, and it makes the GPU wait until the monitor finishes each refresh before sending a new frame. That waiting adds input lag. On a 60Hz panel one refresh cycle takes 16.7ms, on a 120Hz screen 8.33ms and on a 240Hz display 4.17ms, and a good rough guide is to expect about one extra cycle of delay. The lag varies by game and can grow if your GPU can’t keep up and frames start to queue.

Competitive shooter players with NVIDIA cards have one more option, Fast V-Sync, found in the NVIDIA Control Panel’s 3D settings. Instead of making the GPU wait, it lets the card keep rendering, so it cuts tearing without the usual cap. It works best when a game already runs well above your refresh rate, though not every game supports it.

Many games include their own fps limiter in the graphics menu, but those built-in options aren’t always dependable. Setting the cap through your graphics card’s own software is usually the safer route, because it applies across every game.

On an NVIDIA card, you can use the NVIDIA app or the older NVIDIA Control Panel. In the Control Panel, the Max Frame Rate setting lives in the global part of the 3D settings page, where you type in your target.

On an AMD card, the AMD Adrenalin software handles it through Radeon Chill, in the gaming section. Set the lowest and highest frame rate to the same number and you have a system-wide cap.

If you’d rather use a separate tool, the RivaTuner tool, RTSS, can also limit frame rates across many games.
