FPS Test Online — Check Your Frame Rate Instantly

FPS stands for Frames Per Second. It is a measure of how many individual images (frames) your computer's graphics hardware can produce and display on your screen every second. A higher FPS results in smoother motion on screen.

FPS stands for Frames Per Second. In gaming and video contexts, it measures visual smoothness. In other contexts like first-person shooter games, FPS is also an acronym for the game genre itself.

FPS is measured by counting the number of frames your GPU renders within one second. Tools like our online FPS test use the browser's requestAnimationFrame API to count how many times the screen repaints per second, providing an accurate real-time measurement.

Frame time is the duration it takes to render a single frame, measured in milliseconds (ms). At 60 FPS, each frame takes about 16.67ms. Lower frame times mean smoother gameplay. Inconsistent frame times cause stuttering even if average FPS is high.

FPS is how fast your GPU generates frames. Refresh rate (measured in Hz) is how fast your monitor can display new images. They work together — a 144Hz monitor can show up to 144 FPS, but only if your GPU can produce that many frames.

V-Sync (Vertical Synchronization) locks your game's FPS to your monitor's refresh rate to prevent screen tearing. While it eliminates tearing, it can introduce input lag. Alternatives like G-Sync and FreeSync offer tearing prevention without the lag penalty.

Screen tearing occurs when your GPU sends frames to the monitor faster than the display can refresh, causing two or more frames to be visible simultaneously as a horizontal split. V-Sync, G-Sync, and FreeSync technologies solve this issue.

Input lag is the delay between your physical action (like clicking a mouse) and the result appearing on screen. Lower FPS and higher frame times increase input lag, making games feel unresponsive, which is especially critical in competitive gaming.

60 FPS is considered the minimum standard for smooth gaming. For competitive titles like CS2 or Valorant, 144+ FPS is recommended. Casual and single-player games are generally enjoyable at 60 FPS. For VR gaming, 90 FPS is the minimum to prevent motion sickness.

30 FPS is playable for slow-paced games like turn-based strategy or visual novels. However, for action games, shooters, or racing games, 30 FPS will feel noticeably sluggish and can put you at a disadvantage in multiplayer.

Yes, 60 FPS is the gold standard for most gaming. It provides smooth, responsive gameplay for the majority of genres. Many console games target 60 FPS as their performance mode. For most players, 60 FPS on a 60Hz monitor is perfectly enjoyable.

Absolutely, if you have a 120Hz or higher monitor. The jump from 60 to 120 FPS is very noticeable — motion appears much smoother, animations are more fluid, and input lag is reduced. It is particularly beneficial for competitive multiplayer games.

The difference between 120 and 144 FPS is subtle compared to the jump from 60 to 120. Most players won't notice a significant difference. However, 144Hz monitors are very common and affordable, making them a popular choice for gaming.

Professional esports players typically aim for 240+ FPS to minimize input lag. For most competitive players, 144 FPS is an excellent target. The key is consistency — stable 144 FPS is better than fluctuating between 100 and 200.

At 4K resolution, achieving 60 FPS in modern AAA games requires a high-end GPU like an RTX 4080 or RX 7900 XTX. 4K at 120 FPS is possible in less demanding titles. DLSS and FSR can help achieve higher frame rates at 4K.

The visual difference is minimal for most people. However, competitive gamers may notice slightly lower input latency at 360 FPS. Diminishing returns set in after 240 FPS for the vast majority of players.

Use our FPS Test tool at the top of this page. Click 'Start Test' and it will measure your browser's rendering performance using the requestAnimationFrame API, showing current, average, min, and max FPS in real time.

Yes, for measuring browser rendering performance. Our tool uses the same requestAnimationFrame API that powers web animations. Note that browser FPS may differ from in-game FPS because games use different rendering pipelines (DirectX, Vulkan, OpenGL).

Visit our Refresh Rate Test page. It uses precise frame counting to detect your monitor's actual operating refresh rate. Compare the result with your monitor's advertised specifications.

Yes! Our FPS test works on all modern mobile browsers. Mobile devices typically run at 60 FPS, though newer phones like iPhone Pro models and Samsung Galaxy S series support 120Hz displays.

Most browsers cap rendering at 60 FPS by default due to V-Sync matching a 60Hz display. If you have a high refresh rate monitor, make sure your OS display settings are set to the correct Hz (e.g., 144Hz) and your browser isn't limiting frame rates.

Use the built-in FPS counter in Steam (Settings > In-Game > FPS Counter), NVIDIA GeForce Experience (Alt+R), or third-party tools like MSI Afterburner, FRAPS, or CapFrameX for detailed benchmarking.

Common causes include: outdated GPU drivers, high graphics settings, background applications consuming resources, thermal throttling (overheating), insufficient RAM, or a CPU bottleneck. Check our optimization guide for solutions.

Sudden FPS drops often indicate: thermal throttling (GPU/CPU overheating), background Windows updates, antivirus scans, memory leaks in the game, loading new game areas, or running out of VRAM.

This is usually caused by V-Sync being enabled (in-game or GPU control panel), a 60Hz monitor limiting output, an FPS limiter in game settings, or Windows Game Bar's frame rate cap. Disable V-Sync and check your monitor's refresh rate.

This typically indicates thermal throttling — your GPU or CPU heats up over time and reduces clock speeds to prevent damage. Clean your computer's fans and heatsinks, improve airflow, or consider upgrading your thermal paste.

This is likely caused by inconsistent frame times (micro-stuttering). Even at 100+ FPS, if frame times spike irregularly, the game feels choppy. Check for: driver issues, background processes, or enable frame rate limiting slightly below your average.

Micro-stuttering occurs when individual frame delivery times vary significantly. Causes include: multi-GPU setups (SLI/CrossFire), shader compilation stutters, CPU thread scheduling issues, and memory bandwidth constraints.

The most effective methods are: update GPU drivers, lower in-game resolution and graphics settings, close background applications, enable DLSS/FSR, update your game, set Windows to High Performance power plan, and ensure your PC is free from thermal throttling.

Yes, significantly. Resolution is one of the biggest factors in GPU workload. Dropping from 4K to 1440p can nearly double your FPS. Dropping from 1440p to 1080p also provides a substantial boost, especially on mid-range GPUs.

V-Sync caps your FPS to your monitor's refresh rate (e.g., 60, 144). If your GPU can't maintain that rate, V-Sync will drop FPS to the next divisor (e.g., from 60 to 30). This is why G-Sync/FreeSync are preferred alternatives.

Capping FPS slightly below your average can reduce stuttering and frame time variance, providing a more consistent experience. It also lowers GPU temperatures and power consumption. A good rule is to cap at your monitor's refresh rate.

Having enough RAM (16GB minimum for modern games) prevents stuttering from memory swapping. RAM speed (e.g., DDR5-6000) can also impact FPS by 5-15%, especially on AMD Ryzen CPUs where the Infinity Fabric is tied to memory speed.

Both matter. The CPU handles game logic, physics, AI, and draw calls. If your CPU can't prepare frames fast enough, your GPU will wait (CPU bottleneck), limiting FPS. This is especially noticeable in CPU-heavy games like strategy or simulation titles.

DLSS (Deep Learning Super Sampling) is NVIDIA's AI-powered upscaling technology. It renders the game at a lower internal resolution and uses AI to upscale it, providing 40-100% FPS improvements with minimal visual quality loss. FSR is AMD's similar technology.

Yes, overclocking your GPU and CPU can provide 5-15% FPS improvement. However, it increases heat and power consumption, and extreme overclocking can damage hardware if not done carefully. Modern GPUs auto-boost effectively already.

For 1080p 144 FPS in modern AAA games: RTX 4060 Ti or RX 7700 XT or better. For 1440p 144 FPS: RTX 4070 Super or RX 7800 XT. For esports titles at 1080p, even a RTX 3060 or RX 6600 XT can reach 144+ FPS.

Only if you have a monitor with a refresh rate higher than 60Hz. Check your monitor's specifications or Windows display settings (Settings > Display > Advanced Display) to see your current refresh rate.

Check Windows display settings: Right-click desktop > Display Settings > Advanced Display > Choose Refresh Rate. If 144Hz is listed and selected, your monitor is running at 144Hz. You can also use our Refresh Rate Test tool.

It depends on your use case. For competitive gaming, prioritize higher FPS (smoothness and responsiveness). For single-player, story-driven games, or content creation, higher resolution (visual quality) may be preferred.

You need a monitor with a high refresh rate (120Hz, 144Hz, 240Hz) to see the benefit of high FPS. A standard 60Hz office monitor will only display 60 frames per second regardless of how many your GPU produces.

Response time (measured in ms) is how quickly a pixel can change color. It doesn't affect your FPS count but impacts how clearly motion appears. Lower response time (1ms GTG) means less ghosting and blur during fast movement.

Browsers use a different rendering pipeline than games. Games use DirectX/Vulkan with direct GPU access, while browsers render through their compositor. Browser FPS shows your display's rendering capability, not your GPU's gaming performance.

Yes. Multiple browser tabs consume RAM and CPU resources. Browsers like Chrome are particularly memory-intensive. Closing unnecessary tabs can improve both browser and in-game FPS performance.

Yes! Our FPS test works on Chromebooks through the Chrome browser. Most Chromebooks have 60Hz displays, so you should expect to see approximately 60 FPS. This is a great way to test your Chromebook's rendering performance.

No, the stress test is perfectly safe. It generates visual particles in your browser, which increases GPU and CPU usage temporarily. Your hardware has built-in thermal protection that will throttle performance before any damage can occur.

For accurate results, run the test for at least 30 seconds. For stability testing, let it run for 5-10 minutes. The longer you run it, the more accurate the Average, Min, and 1% Low values become.

The 1% Low shows the FPS that your system only drops below 1% of the time. It measures your worst-case performance and is a better indicator of stuttering than average FPS. A large gap between Average and 1% Low indicates inconsistent performance.
