What Are Frame Drops?

Frame drops occur when your computer cannot render frames fast enough to maintain a smooth, consistent frame rate. A frame drop is a momentary decrease in the number of frames displayed per second. If your game is running at 60 FPS and suddenly drops to 30 FPS or lower, you will experience a noticeable stutter or lag. Frame drops can be caused by a single bottleneck that momentarily limits performance, or they can be caused by a persistent issue that keeps the frame rate below its target.

Understanding the difference between low average FPS and frame drops is important. Low average FPS means your system consistently cannot reach the target frame rate, usually because the hardware is not powerful enough for the workload. Frame drops, on the other hand, are intermittent decreases from an otherwise acceptable frame rate. A system that maintains 60 FPS most of the time but occasionally dips to 40 FPS is experiencing frame drops. Both problems are annoying, but they have different causes and solutions. This guide focuses primarily on frame drops, though many of the fixes also apply to low average FPS.

Thermal Throttling

Thermal throttling is the most common cause of frame drops in laptops and desktop PCs alike. When your CPU or GPU reaches its maximum safe temperature, it automatically reduces its clock speed to prevent damage from overheating. This reduction in clock speed directly causes a drop in performance, which manifests as frame drops during gaming or other demanding tasks. The transition from full speed to throttled speed can happen in seconds, causing sudden and dramatic frame drops.

The symptoms of thermal throttling are distinctive. Your game runs smoothly for a period, then suddenly the frame rate drops significantly, and it stays low for a while before recovering. This cycle often repeats as the component heats up, throttles, cools slightly, throttles less, heats up again, and so on. To check for thermal throttling, monitor your CPU and GPU temperatures using tools like HWiNFO, MSI Afterburner, or Core Temp. If your CPU exceeds 90 degrees Celsius or your GPU exceeds 85 degrees Celsius during gaming, thermal throttling is likely the cause. For tips on reducing GPU temperatures, see our guide on how to lower GPU temp.

GPU Bottleneck

A GPU bottleneck occurs when your graphics card is the limiting factor in your system. If your GPU is working at 100% utilization but your frame rate is still lower than desired, the GPU does not have enough processing power to render frames at the target rate. This is one of the most common causes of frame drops in gaming, especially when playing modern titles with demanding graphics settings.

GPU bottlenecks are more likely to occur when you increase the resolution or enable demanding features like ray tracing, anti-aliasing, and high shadow quality. If you notice that your frame drops are worse at higher resolutions or with certain graphics settings enabled, the GPU is likely the bottleneck. The solution is to lower GPU-demanding settings, reduce the resolution, or upgrade to a more powerful graphics card. Monitoring GPU utilization while gaming helps confirm whether the GPU is the bottleneck. If GPU utilization is consistently at 95-100% during frame drops, upgrading the GPU will provide the biggest performance improvement.

CPU Bottleneck

A CPU bottleneck occurs when your processor cannot prepare data fast enough for the GPU to render. When the CPU is the bottleneck, the GPU has spare capacity but is waiting for the CPU to finish its work. This results in lower GPU utilization and frame drops because the GPU cannot maintain a consistent workload. CPU bottlenecks are common in CPU-intensive games, simulation titles, and strategy games with many AI-controlled entities.

The symptoms of a CPU bottleneck include low GPU utilization (often below 80%) during gaming, frame drops in CPU-heavy scenes, and overall lower performance than expected given the GPU’s capabilities. If your CPU usage is consistently at or near 100% during gaming, the CPU is definitely the bottleneck. You can reduce CPU bottleneck by lowering CPU-dependent settings like draw distance, AI complexity, and physics quality. Upgrading to a faster CPU with more cores and higher clock speeds is the most effective long-term solution.

Background Processes

Background processes are one of the most overlooked causes of frame drops. Applications running in the background, such as web browsers with multiple tabs, streaming software, antivirus scans, Windows updates, and system utilities, can consume CPU, GPU, and RAM resources that would otherwise be available for gaming. Even processes that do not appear to be doing much can occasionally spike in CPU usage, causing momentary frame drops.

To identify background processes that may be causing frame drops, open Task Manager while gaming and look at the CPU, GPU, and Memory columns. Sort by usage to find processes that are consuming significant resources. Common culprits include web browsers with hardware acceleration enabled, Discord with its overlay active, antivirus software running real-time scans, and Windows Update downloading updates in the background. Close or disable unnecessary background processes before gaming to free up resources. Some antivirus software allows you to schedule scans during non-gaming hours, and Windows Update can be configured to not download updates while you are using the computer for gaming.

Driver Issues

Graphics driver issues are a frequent cause of frame drops. Outdated, corrupted, or buggy drivers can prevent the GPU from performing optimally, leading to inconsistent frame rates and stuttering. Driver issues can be particularly frustrating because they may appear suddenly after a seemingly unrelated software update or system change.

To address driver-related frame drops, start by updating to the latest stable driver from your GPU manufacturer. For NVIDIA GPUs, use GeForce Experience or download directly from NVIDIA’s website. For AMD GPUs, use Radeon Software or download from AMD’s website. If you recently updated your drivers and the frame drops started, try rolling back to the previous driver version. Sometimes, the latest driver introduces new bugs that affect specific games or hardware configurations. Clean driver installations, where you completely remove the old driver before installing the new one, can also resolve persistent driver issues. Tools like Display Driver Uninstaller (DDU) can help ensure a completely clean installation.

Game Settings Optimization

Inappropriate game settings are a common cause of frame drops, especially when the settings are too demanding for your hardware. Features like ray tracing, ultra-quality shadows, high-resolution textures, and maximum anti-aliasing can push your GPU beyond its capabilities, causing frame drops. The key is to find the right balance between visual quality and performance for your specific hardware.

To optimize game settings, start by lowering the most GPU-demanding settings first. Shadow quality, volumetric lighting, and screen-space reflections are typically the most performance-hungry settings. Anti-aliasing, especially MSAA, is also very demanding. Reducing these settings from Ultra to High or Medium can provide significant performance gains with minimal visual impact. Resolution scaling is another powerful tool. Running the game at a slightly lower resolution, such as 90% render scale, can improve frame rates without a noticeable loss in visual quality. Many games also offer performance presets that automatically configure settings for optimal performance on your hardware.

RAM and Memory Issues

Insufficient RAM or slow memory can cause frame drops, particularly in modern games that require large amounts of memory. When your system runs out of physical RAM, it starts using the page file on your storage drive, which is much slower. This transition from RAM to page file causes noticeable stuttering and frame drops as the system swaps data back and forth. Running out of RAM is increasingly common as modern games require 16GB or more for optimal performance.

To check if RAM is causing frame drops, monitor your memory usage while gaming. If your RAM usage is consistently above 90%, you may need more memory. Upgrading from 8GB to 16GB is one of the most cost-effective performance upgrades you can make. RAM speed and configuration also matter. Running dual-channel memory (two matching sticks) provides better performance than single-channel, and faster RAM can improve frame rates in CPU-bound scenarios. Make sure your RAM is running at its rated speed by enabling XMP or DOCP in your BIOS, as many systems default to slower JEDEC speeds.

Power Settings

Power settings can significantly impact your system’s performance, especially on laptops. Windows power plans control how much power is allocated to the CPU, GPU, and other components. The Balanced power plan, which is the default on most systems, reduces CPU clock speed when full performance is not needed. This can cause frame drops when the system does not ramp up the clock speed fast enough in response to sudden performance demands.

To ensure maximum performance, switch your power plan to High Performance or Ultimate Performance. On Windows 10 and 11, go to Settings, then System, then Power & sleep, then Additional power settings. Select the High Performance plan. For laptops, you can also use the battery slider in the system tray to set the performance level to Best Performance. Additionally, check your GPU’s power management settings in the NVIDIA Control Panel or AMD Radeon Software. Setting the power management mode to Prefer maximum performance ensures the GPU maintains its clock speeds during gaming.
