From there, look for AA techniques that the game identifies as less GPU-intensive: FXAA, for example, has a smaller impact than MSAA. Reducing the number of samples taken (from 4x to 2x, for example) is a good first step to improve performance. Anti-aliasing techniques take samples of pixels onscreen in order to guess the correct color of neighboring pixels, then fill in the gaps to clean up sawtooth edges. Turning up these settings will lead to smoother shadows, but leaving them set to medium or low may lead to frame rate gains with little visible impact in fast-paced titles.Īnti-aliasing (AA) smooths out the jagged edges (an artifact called “aliasing”) that appear on digital objects made out of square pixels. These techniques work to smooth out sawtooth edges, accurately represent the shapes casting shadows, and help shadows match the movements of their source. Shadow settings may cover a number of shadow mapping techniques with differing performance impact, from CPU-intensive shadow volumes to GPU-intensive techniques like ray tracing, which calculates all the rays emanating from every individual light source. Here are a few common settings to turn down (or off) for measurable performance boosts. However, if you’re reading this article, you might have found that those settings don’t give frame rate the priority you’d like.

Most games will automatically test your PC after installation and assign custom settings. In Steam, you can do so by opening the Library tab, right-clicking the game, and then clicking “Properties.” Once in the Properties window, click the “Local Files” tab, then “Verify Integrity of Game Files.” If performance issues in one game are unusually severe, try repairing the installation. This may result in immediate performance gains. If your graphics utility has this capability, make sure that it has recognized the game you’re trying to play. Utilities for discrete graphics cards may also automatically detect installed games. If you’re using an Intel® Core™ processor (4th Gen or later) with integrated graphics, try looking up the game on to find recommended settings.

New graphics drivers for both discrete GPUs and integrated GPUs are released regularly to optimize for recent games. Enable automatic updates to ensure you don’t miss one. Especially early in the life cycle of a game, developers release patches with major performance impacts. Next, make sure the game itself is up to date. Open the Task Manager (CTRL+SHIFT+ESC), then click the CPU and Memory tabs to check whether anything is using up large chunks of your CPU or RAM (for instance, a web browser with dozens of tabs open). However, if you already own a display with a higher refresh rate, such as 144Hz, you’ll see immediate onscreen benefits from higher frame rates.įirst, make sure no other programs are slowing things down.

If your monitor has a refresh rate of 60Hz, you won’t see benefits from frame rates over 60 FPS, as your monitor won’t update fast enough to keep up with the output of your GPU. Your monitor’s refresh rate is a good target for in-game frame rates. PC games can often achieve higher frame rates than current-generation console titles, but the real advantage of PC gaming is the freedom to tune your settings and find the frame rate that best suits your hardware - especially your monitor. If you watch a side-by-side comparison of a game running at 30 FPS and 60 FPS, you’ll see the difference immediately: At higher frame rates, the game appears smoother and more lifelike. In games, though, 24 FPS can look choppy and unnatural. Games didn’t invent the frames per second measurement: Movies are traditionally projected at 24 FPS, meaning 24 still images flash by onscreen every second. Reduced frame rate can be caused by unoptimized code, glitches, or in-game settings that create a larger workload than your hardware can handle. When one component in the chain causes a bottleneck - for example, your CPU tells your GPU to render a large number of objects at once - your PC draws fewer frames per second. Your graphics card, CPU, and RAM are all involved in the effort to create the geometry, textures, lighting, and effects that compose one of those frames. It all adds up to a less immersive experience, but what causes it? Frame rate, measured in frames per second (FPS), reports the number of times your graphical hardware redraws the screen every second. Your view starts looking like a slideshow, things get visibly choppy when you turn the camera fast, and swaying objects like hair or banners move less fluidly. Often, a game is running fine, then begins to stutter when your character enters a big city or complex environment. Almost every player has encountered low frame rates.
