Limit Your FPS in Games: When It Makes Sense

If you are passionate about PC gaming, you likely prioritize frame rates. even with a top-of-the-line gaming setup, you should carefully consider the advantages of capping your in-game fps. For gamers seeking improved GPU performance without the expense of new hardware, applying a frame rate cap can be a smart choice. This approach not only helps to eliminate screen tearing when used alongside V-Sync (vertical synchronization) but also reduces the workload on your GPU.

In most gaming scenarios, it is advisable to cap your frame rates. Establishing a frame rate limit can help achieve stable performance—assuming your hardware can support it—while minimizing the likelihood of screen tearing. capping frame rates reduces the strain on your GPU, leading to quieter operation and lower overall power consumption.

Implementing a frame rate cap is particularly beneficial if you utilize a VRR (Variable Refresh Rate) monitor. By doing so, you can keep your gameplay within the effective VRR range, which typically begins at 48 fps and culminates at your display’s maximum refresh rate. Setting a frame rate cap on a VRR monitor ensures that your game does not exceed the refresh rate limit, slightly decreasing latency. When paired with V-Sync (more on this shortly), capping fps will help you avoid screen tearing.

Screen tearing occurs when your GPU sends a new frame to your monitor or TV while the previous frame is still being displayed. This results in portions of both frames appearing on-screen simultaneously, creating unsightly flickering horizontal lines during movement. This visual artifact not only looks bad but can also be distracting, making it a significant issue for gamers.

For years, I’ve capped my frame rates to achieve the smoothest and most visually consistent gameplay on my NVIDIA G-Sync compatible display. I typically do not set a minimum fps threshold because both G-Sync and AMD’s FreeSync technology synchronize a display’s refresh rate with the frame output from the GPU. Given that I play on a custom RTX 5090 setup, frame drops are infrequent. when the frame rate dips from 120 fps to 110 fps, I hardly notice it.

The simplest way to cap a game’s frame rate is to utilize an fps limiter. Many games include this feature in their graphics settings, although they may not always function reliably. A more dependable method is to cap your frame rate through your GPU’s software.

Users with NVIDIA graphics cards can utilize either the NVIDIA app or the NVIDIA Control Panel. To do this via the Control Panel, navigate to Manage 3D Settings > Global Settings > Max Frame Rate and set your desired fps target. For those with AMD graphics cards, frame rates can be capped at a system-wide level using AMD Adrenalin. Simply go to Gaming > Radeon Chill and set both the minimum and maximum fps to the same value. Alternatively, you can explore third-party applications like Guru3D RTSS RivaTuner.

The optimal output frame rate depends on your display’s maximum refresh rate. Generally, a combination of V-Sync and a frame rate cap set three to four frames below your display’s maximum will effectively prevent screen tearing. For instance, if you have a 60Hz monitor, aim for 57 fps. For a 120Hz monitor, set it to 117 fps, and for a 240Hz display, try 237 fps.

On VRR displays, capping your frame rate slightly below the maximum refresh rate can help mitigate lag, although the effect may be minimal. If you have concerns about losing a few frames, don’t fret. The difference between 57 and 60 fps, or 237 and 240 fps, is typically imperceptible. As long as your GPU is powerful enough to maintain the set frame rate, you can enjoy a smooth, tear-free gaming experience.

If you’re curious about the impact of V-Sync on your PC’s frame rates, the primary function of V-Sync is to limit the fps to a level that does not exceed your display’s maximum refresh rate. For example, on a 120Hz monitor, V-Sync ensures that your in-game performance will not exceed 120 fps when enabled.

V-Sync synchronizes the frame rate of a game with the refresh rate of your monitor or TV. This means that before your GPU can generate a new frame, V-Sync compels it to wait until the display’s refresh cycle has completed. This introduces a delay of 16.7ms for 60Hz monitors, 8.33ms for 120Hz displays, and just 4.17ms for ultra-fast 240Hz screens.

The obvious benefit of V-Sync is its effectiveness in eliminating screen tearing, which can significantly disrupt immersion. there is a notable drawback to enabling V-Sync: it introduces unavoidable input lag.

The amount of latency caused by V-Sync can vary depending on the game you are playing. As a general guideline, expect an increase of one additional refresh cycle of lag. For a 120Hz monitor, that translates to 8.33ms. If your GPU cannot render frames quickly enough, queued frames can accumulate, further increasing latency.

In my experience, V-Sync does not typically introduce noticeable lag. For competitive shooter enthusiasts who demand the smoothest performance for accurate aim, NVIDIA’s Fast V-Sync is worth experimenting with. This feature, found in the NVIDIA Control Panel under Manage 3D settings, aims to reduce the typical lag associated with standard V-Sync while also minimizing tearing.

Fast V-Sync allows the GPU to continue rendering frames without waiting for the refresh cycle to conclude, which means it does not impose a strict fps limit like traditional V-Sync. I’ve achieved smooth results with Fast V-Sync in games where my frame rate consistently exceeds my monitor’s refresh rate; if you frequently find yourself in this situation, it’s an alternative solution to prevent tearing, although it may not be compatible with all games.
