What is gaming performance?
Gaming performance is how smoothly and responsively a game runs on your PC. It is usually measured in frames per second (FPS), along with how steady those frames are and how quickly the game responds to your input. Good gaming performance means high, consistent frame rates, sharp visuals, and controls that feel immediate.
Performance depends on how well your hardware matches the game's demands. The graphics card does most of the work, but the processor, memory, storage, cooling, and even your settings and software all play a part. When one of those falls short, you may notice low frame rates, stutter, or a PC that slows down after a few minutes of play.
This guide explains what FPS means, how to read game system requirements, what causes bottlenecks and thermal throttling, and how to optimize your PC for better gaming performance.
What is FPS in gaming?
FPS, or frames per second, is the number of images your PC produces and displays each second while you play. Higher FPS makes motion look smoother and helps the game respond faster to your actions. The graphics card is the main factor in FPS, followed by the processor.
What is a good FPS for gaming?
Frame rate | What it feels like | Typical use |
|---|---|---|
Below 30 FPS | Choppy and sluggish | Generally too low for comfortable play |
30 FPS | Playable but not smooth | Slower-paced games on modest hardware |
60 FPS | Smooth for most players | A common target for most games |
120 to 144 FPS | Noticeably smoother and more responsive | Fast-paced and online games, with a high-refresh-rate display |
240 FPS and above | Extremely fluid, with fast feedback | Competitive shooters and esports |
To see the benefit of high FPS, your display's refresh rate needs to keep up. Our display features guide explains refresh rate.
Frame time and 1% lows
Average FPS does not tell the whole story. Two other measures explain why a game can feel uneven even with a high average:
Frame time: How long each individual frame takes to appear, measured in milliseconds. At 60 FPS, each frame takes about 16.7 ms. Consistent frame times feel smooth, while sudden spikes feel like stutter.
1% lows: The frame rate during the slowest 1% of frames. A big gap between average FPS and 1% lows means occasional hitches, even if the average looks good.
For the smoothest experience, aim for steady frame times and 1% lows that stay close to your average FPS.
Game system requirements explained
Game system requirements are the hardware and software specifications a developer lists to show what a PC needs to run a game. Most games list at least two levels: minimum and recommended.
Requirement level | What it means |
|---|---|
Minimum | The lowest hardware that can launch and run the game, usually at low settings, 1080p or lower, and around 30 FPS |
Recommended | Hardware for a good experience, usually at medium to high settings and around 60 FPS at a common resolution |
High or ultra (when listed) | Hardware for top settings, higher resolutions, ray tracing, or high frame rates |
Developers set their own targets, so check the resolution, settings, and frame rate each tier is based on when they are listed.
What system requirements include
Operating system: The supported version of Windows or other platform
Processor (CPU): A minimum model or performance level
Graphics card (GPU): A minimum model, and sometimes the VRAM required
Memory (RAM): The amount of system memory needed
Storage: The free space required, and often whether an SSD is needed
DirectX or other API version: The graphics technology the game uses
How to check your PC's specs on Windows
Open Settings, select System, then About to see your processor and installed RAM.
Open Task Manager and select the Performance tab to see your GPU, memory, and storage.
Compare these with the game's listed requirements, focusing first on the graphics card.
If your PC falls between minimum and recommended, you can usually still enjoy the game by lowering some settings or turning on upscaling. Our graphics cards guide explains how to compare GPUs.
What is a bottleneck in gaming?
A bottleneck happens when one component limits the performance of the rest of your system. In gaming, it usually means either the processor or the graphics card is holding back your frame rate, while the other part has capacity to spare.
CPU bottleneck vs. GPU bottleneck
CPU bottleneck | GPU bottleneck | |
|---|---|---|
What is happening | The processor cannot prepare frames fast enough for the GPU | The graphics card is working at full capacity |
Common signs | GPU usage well below 100% while FPS stays low; stutter in busy scenes | GPU usage near 100%; FPS drops when you raise graphics settings |
When it shows up | Low resolutions, high refresh rates, games with many characters or complex simulations | High resolutions, high graphics settings, ray tracing |
How to improve it | Lower settings that load the CPU, such as crowd density; close background apps; upgrade the CPU | Lower resolution or settings; turn on upscaling; upgrade the GPU |
A GPU bottleneck is normal and often expected in demanding games, since the graphics card is meant to work hardest. A CPU bottleneck is more noticeable in competitive games, where players chase very high frame rates.
Other bottlenecks
Memory: Too little RAM causes stutter and slowdowns, especially with browsers or chat apps open alongside the game.
Storage: A slower hard drive can cause long load times and textures that pop in late. A solid-state drive fixes most of these issues.
Power and cooling: A laptop on battery power, or a system that overheats, can limit how hard the CPU and GPU are allowed to work.
What is thermal throttling?
Thermal throttling is when a processor or graphics card automatically slows itself down to avoid overheating. It is a built-in safety feature that protects your hardware, but it lowers performance, so frame rates may drop or stutter after you have been playing for a while.
Gaming pushes the CPU and GPU hard, and both produce a lot of heat. When the cooling system cannot remove heat fast enough, the chips reduce their clock speeds and power until temperatures come back down.
Signs of thermal throttling
Frame rates start high, then drop after several minutes of play
Fans run at full speed and the PC feels hot to the touch
Performance improves after the PC cools down
Monitoring tools show high CPU or GPU temperatures alongside falling clock speeds
How to prevent thermal throttling
Give your PC room to breathe. Keep vents clear, and use a laptop on a hard, flat surface rather than a bed or couch.
Clean out dust. Dust buildup on fans and vents blocks airflow. Follow the manufacturer's guidance for safe cleaning.
Use the right performance mode. Many gaming PCs include system software with cooling and fan profiles. Choose a performance or cooling mode for gaming.
Improve airflow in desktops. Make sure case fans move air in at the front and out at the back or top, and consider better cooling if temperatures stay high.
Try a laptop cooling pad. An external fan pad can help lower gaming laptop temperatures.
Cap your frame rate. Limiting FPS to your display's refresh rate reduces unnecessary work and heat.
Keep the room cool. High room temperatures make it harder for any cooling system to keep up.
Our gaming laptops vs. desktops guide explains how cooling differs between the two.
Graphics settings explained
In-game graphics settings let you trade visual quality for frame rate. Some settings make a big difference to performance with little visible change, while others change how a game looks a lot. Knowing which is which helps you get the best balance.
Setting | What it does | Performance impact |
|---|---|---|
Resolution | Sets the number of pixels rendered | Very high; the biggest single factor |
Upscaling (DLSS, FSR, XeSS) | Renders at a lower resolution and reconstructs a sharp image | Improves FPS significantly |
Ray tracing | Simulates realistic lighting, reflections, and shadows | Very high |
Shadow quality | Controls shadow sharpness and draw distance | Medium to high |
Volumetric effects (fog, clouds, lighting) | Adds atmospheric depth | Medium to high |
Anti-aliasing | Smooths jagged edges | Low to high, depending on the method |
Texture quality | Sets the detail of surface images | Low on FPS, but needs enough VRAM |
Draw distance | Controls how far away objects appear | Medium; can also load the CPU |
Ambient occlusion | Darkens corners and contact points for depth | Low to medium |
Motion blur and film grain | Adds cinematic effects | Low; often turned off for clarity |
Quick wins for higher FPS
Turn on upscaling in Quality or Balanced mode.
Lower shadows and volumetric effects one step before reducing anything else.
Keep texture quality high if your graphics card has enough VRAM, since it costs little FPS.
Turn off ray tracing in fast competitive games.
Learn more about upscaling and ray tracing in our graphics cards guide.
How to optimize gaming performance
You can often raise frame rates and reduce stutter without buying new hardware. Work through these steps in order, starting with the easiest:
Update your graphics drivers. New drivers often include performance improvements and fixes for recent games. See our gaming software guide.
Update Windows and the game. Patches frequently improve performance and stability.
Plug in your laptop. Gaming laptops reduce GPU power on battery. Connect the charger for full performance.
Choose a high-performance power and cooling mode. Use Windows power settings and your PC maker's system software to select a performance profile.
Make sure the game uses your dedicated GPU. On laptops with both integrated and dedicated graphics, check Windows graphics settings or your GPU control panel.
Turn on Game Mode. Windows Game Mode prioritizes the game and limits background activity.
Close background apps. Browsers, video streams, and downloads compete for CPU, memory, and bandwidth.
Adjust in-game settings. Turn on upscaling, then lower demanding settings such as shadows, volumetric effects, and ray tracing.
Match frame rate to your display. Turn on adaptive sync and consider capping FPS just below your display's maximum refresh rate for smooth, consistent frames. Our display features guide explains how.
Install games on an SSD. Solid-state drives reduce load times and texture pop-in.
Keep your PC cool. Clean vents and fans, and give your PC good airflow to prevent thermal throttling.
When to upgrade
If a game still runs poorly after these steps, check whether your CPU or GPU is the bottleneck. On a desktop, upgrading the graphics card or adding RAM often delivers the biggest gains. On a laptop, adding RAM or a faster SSD may help when the model supports upgrades.
Input lag and system latency
Input lag, also called system latency, is the delay between your action, such as a mouse click, and seeing the result on screen. Lower latency makes a game feel more responsive, which matters most in fast competitive games.
Latency builds up across your whole setup:
Peripherals: How quickly your mouse, keyboard, or controller sends input to the PC. See our gaming peripherals guide.
PC processing: How long the CPU and GPU take to process the input and produce a frame. Higher FPS generally lowers this delay.
Display: How quickly the screen shows the new frame, which depends on refresh rate, response time, and processing.
How to reduce input lag
Raise your frame rate by lowering demanding settings or using upscaling.
Turn on latency-reduction features in supported games, such as NVIDIA Reflex or AMD Anti-Lag.
Use a high-refresh-rate display with game mode enabled.
Use wired or low-latency wireless peripherals.
Avoid stacking frame generation on very low base frame rates, as it can make controls feel less responsive.
Input lag is different from network lag. If online games feel delayed even at high FPS, the problem may be your connection. Our gaming networking guide covers ping and latency.
Gaming performance frequently asked questions
Why is my FPS low?
Low FPS usually comes from graphics settings or resolution set too high for your GPU, outdated drivers, a laptop running on battery, background apps, or thermal throttling. Start by updating drivers, plugging in, and lowering demanding settings such as shadows and ray tracing.
Why does my game stutter even with high FPS?
Stutter with a high average FPS usually means uneven frame times or low 1% lows. Common causes include a CPU bottleneck, too little RAM, shader compilation in new games, background tasks, or a frame rate that exceeds your display's adaptive sync range. Capping your frame rate and closing background apps often helps.
How do I check my FPS?
Many games include a built-in FPS counter in their settings. You can also use the performance overlay in your graphics driver software or in the Windows Game Bar, which you open with the Windows key + G.
What temperature is too hot for gaming?
Safe temperatures vary by processor and graphics card, and modern chips are designed to throttle before damage occurs. Check your manufacturer's specifications. If performance drops as temperatures rise, improving airflow and cleaning dust usually helps.
Does more RAM increase FPS?
More RAM increases FPS only if your PC does not have enough for the game. If a game needs more memory than you have, adding RAM can reduce stutter and raise frame rates. Beyond that point, extra RAM has little effect on FPS.
Can I run a game below the minimum requirements?
Sometimes, but expect low frame rates, reduced settings, or crashes. The minimum requirements are the developer's tested baseline, so performance below that level is not guaranteed.
Does upscaling really improve performance?
Yes. Upscaling technologies such as DLSS, FSR, and XeSS render the game at a lower resolution and reconstruct a sharp image, which can raise frame rates substantially with little visible loss in quality. See our graphics cards guide.
Is thermal throttling bad for my PC?
Thermal throttling protects your hardware rather than harming it, but it lowers performance. If it happens often, improve your PC's cooling and airflow to keep performance steady.
