Average FPS tells you how fast a game runs overall. 1% low FPS adds context about how performance holds up during the slower parts of gameplay. A gaming PC can post a strong average frame rate and still feel less smooth when slower frames, dips, or brief stutters appear.

This guide explains what 1% low FPS means, how it compares with average FPS and frametime, what can cause poor 1% lows, how to improve them, and how the metric can help you choose the right CPU, GPU, and gaming PC for your resolution and refresh-rate target.

THE SHORT ANSWER

What Is 1% Low FPS?

1% low FPS is a gaming benchmark metric that summarizes the slower portion of a performance test. It is not simply the single lowest FPS number recorded.

Used with average FPS, 1% lows help show how the system performs during the slower parts of the run. If average FPS is high but 1% lows are much lower, you may notice more dips, hitches, or uneven frame delivery.

Benchmark tools can calculate 1% lows differently, so compare results using the same game, settings, tool, and test method whenever possible.

Simple takeaway: average FPS shows overall speed; 1% low FPS adds context about how well that speed is maintained.

THE NUMBERS THAT MATTER

1% Low FPS vs Average FPS vs Frametime

These three measurements describe different parts of gaming performance. Together they give a more complete picture than average FPS alone.

METRIC WHAT IT MEANS WHY IT MATTERS BEST USE
Average FPS The average rate of frame delivery across the test Shows overall gaming performance, but can hide brief slowdowns Compare general performance
1% Low FPS A summary of the slower part of the benchmark Adds context about performance dips and low-end consistency Judge performance alongside average FPS
Frametime How long individual frames take to be delivered Large spikes can reveal when visible stutter occurs Troubleshoot uneven frame delivery

For a fair gaming PC comparison, keep the game, scene, resolution, graphics settings, and benchmark method the same.

WHY IT MATTERS

Why 1% Low FPS Matters for Gaming Performance

Average FPS shows overall speed. 1% lows add context about what happens when slower frames appear during the run.

AVERAGE FPS

Average FPS Looks Strong

A gaming PC might average 160 FPS, which accurately shows that the system is fast overall.

PERFORMANCE DIP

A Few Frames Slow Down

Busy scenes, CPU limits, heavy GPU load, shader compilation, asset streaming, or background tasks can make some frames take longer.

WHAT YOU FEEL

You Feel the Hitch

Those slower frames can appear as a brief stutter even when they barely change the final average-FPS number.

1% LOWS

1% Lows Add the Missing Context

The 1% low summarizes part of that slower frame delivery, giving you another way to judge performance alongside average FPS.

FRAME DELIVERY

What Is Frametime and How Does It Relate to 1% Lows?

Frametime describes the timing associated with individual frames. At a perfectly even pace, 60 FPS is about 16.67 milliseconds per frame, 144 FPS is about 6.94 ms, and 240 FPS is about 4.17 ms.

You do not need to memorize those numbers. What matters is consistency. If most frames arrive quickly but one takes much longer, that delay can appear as visible stutter. That is why two gaming PCs with similar average FPS can sometimes feel different in the same game.

Average FPS shows overall speed, 1% low FPS summarizes the slower part of the run, and a frametime graph helps show when those slower frames occurred.

UNDERSTANDING THE RESULT

What Is a Good 1% Low FPS?

There is no universal good 1% low FPS number and no required percentage of average FPS that every game should maintain. The useful target depends on the game, resolution, graphics settings, CPU, GPU, refresh rate, and benchmark method.

A demanding 4K game should not be judged by the same raw FPS target as competitive 1080p or 1440p gaming. For buyers, the important question is whether the PC delivers the level of performance and consistency needed for the games, settings, and monitor being used.

In a controlled comparison, similar average FPS with stronger 1% lows and less visible stutter is useful evidence of better low-end performance.

COMMON CAUSES

What Causes Poor 1% Low FPS in Games?

Poor 1% lows can come from the CPU, GPU, RAM, VRAM, cooling, background software, drivers, or the game itself. The metric tells you that slower frames occurred; it does not identify a bad component by itself.

Gaming PC Causes to Check

These system-side limits can reduce frame-rate consistency when the workload pushes them hard enough.

CPU limits in high-refresh, simulation-heavy, or CPU-sensitive games
High GPU load from higher resolution, ray tracing, or demanding graphics settings
Too little usable system RAM or graphics memory for the workload
Thermal, power, or stability problems that reduce sustained performance
Background apps, overlays, recording, drivers, or updates competing for resources

Game-Side Causes to Check

Some stutter comes from the game and can remain even on a powerful gaming PC.

Shader compilation
Asset streaming or traversal stutter
Game-engine scheduling or optimization
A game patch or driver interaction
A short or inconsistent benchmark run

Poor 1% lows are a reason to investigate—not proof that your gaming PC needs a new CPU, GPU, RAM kit, SSD, or complete system.

IMPROVE CONSISTENCY

How to Improve 1% Low FPS

Start with the easiest causes before buying new hardware. Change one thing at a time, repeat the same game scene, and look for an improvement that happens consistently.

01

Confirm the Problem Is Repeatable

Run the same scene again before changing anything. One isolated hitch can come from a background task, first-run shader work, or another one-off event.

02

Close Background Apps and Check Software

Close unnecessary launchers, browsers, overlays, and recording tools. If the problem began after a game, driver, or Windows change, retest after reversing that specific change when practical instead of changing several things at once.

03

Check Whether the GPU Is the Limit

If the GPU is heavily loaded, lower resolution, ray tracing, or other demanding graphics settings. If average FPS and 1% lows improve repeatedly, more GPU headroom may help at that target.

04

Check CPU, RAM, and VRAM Pressure

If the GPU has headroom, look at CPU-heavy situations and memory use. Reducing CPU-heavy settings, background workload, or memory-heavy graphics settings can help reveal whether the CPU, system RAM, or VRAM is contributing.

05

Upgrade Only After You Find the Real Limit

Check temperatures, clocks, cooling, power connections, and system stability under load. If a repeatable CPU or GPU limit remains after the easier causes are ruled out, choose an upgrade that directly addresses that proven limit.

RivaTuner can display FPS, 1% lows, frametime, GPU usage, CPU usage, temperatures, RAM, and VRAM while a game is running.

CPU PERFORMANCE

Can a Better CPU Improve 1% Low FPS?

Yes, when the game is actually CPU-limited. A faster gaming CPU can improve average FPS and 1% lows in high-refresh gaming, competitive titles, simulation-heavy games, and other workloads where the GPU still has performance headroom.

Total CPU usage does not need to reach 100% for a CPU bottleneck to exist because one or more game threads can become the limit first. If lowering resolution barely changes performance while the GPU has headroom, the CPU side deserves a closer look.

Cooling only matters when temperature is genuinely limiting sustained CPU performance. Valhalla’s CPU cooling and gaming performance guide explains when thermals can affect gaming performance.

For buyers targeting high FPS at 1080p or 1440p, the Performance Series Berserker and Valhalla’s 1080p gaming PCs are built around high-refresh gaming targets where CPU headroom can become increasingly important.

GPU PERFORMANCE

Can a Better GPU Improve 1% Low FPS?

Yes, when the graphics card is already the main performance limit. Higher resolution, ray tracing, and demanding graphics settings can increase GPU load and reduce both average FPS and 1% lows.

If lowering render resolution or GPU-heavy settings improves both numbers in the same scene, the system likely needs more graphics headroom for that target. VRAM pressure is a separate consideration: when a game’s memory demand exceeds what the graphics card can handle efficiently, performance or smoothness can suffer. A high VRAM allocation number by itself does not prove a VRAM bottleneck.

For high-refresh 1440p and stronger 4K gaming, Valhalla’s RTX 5080 gaming PCs provide one current performance tier for buyers targeting heavier graphics workloads. The right GPU still depends on the games, resolution, settings, ray tracing, and monitor refresh rate you want to drive.

DISPLAY SMOOTHNESS

Do FreeSync or G-SYNC Improve 1% Low FPS?

FreeSync and G-SYNC do not make the CPU or GPU render frames faster, so they do not fix the underlying cause of poor 1% lows. Variable refresh rate can reduce tearing and make normal FPS variation look smoother by matching a compatible monitor to changing frame delivery.

A true rendering hitch still exists even when VRR is working correctly. Valhalla’s FreeSync and G-SYNC guide explains how variable refresh rate fits into the complete gaming experience.

For buyers, the monitor is part of the performance target: resolution and refresh rate help determine how much CPU and GPU performance the gaming PC needs.

THE COMPLETE GAMING PC

Why a Balanced Gaming PC Delivers More Consistent Performance

A gaming PC should be matched to the games, resolution, refresh rate, and workload—not built around one impressive benchmark number.

Valhalla starts with the experience the system needs to deliver. The CPU, GPU, memory, cooling, storage, power supply, and motherboard are matched as one platform around the target resolution, refresh rate, games, graphics settings, and other workloads.

After assembly, Valhalla checks CPU thermals, GPU behavior, memory stability, storage health, power behavior, cooling response, WHEA errors, and overall system responsiveness before shipment. Those checks are part of the Valhalla build and validation process where the finished gaming PC is evaluated as one complete system.

CPU and GPU matched to the target resolution, refresh rate, games, and workload

Memory configured and checked for stability

Windows, chipset drivers, graphics drivers, and required updates prepared

CPU and GPU temperatures and cooling behavior checked under load

Power supply and power connections matched to the hardware

Storage configuration and drive health checked

Unexpected temperatures, driver issues, WHEA errors, and instability investigated

Problems corrected and the system tested again before shipment

The goal is a gaming PC that performs consistently in the experience it was built for—not simply one that looks fast on a specification sheet.

CHOOSING A GAMING PC

How 1% Low FPS Should Influence Your Gaming PC Purchase

Average FPS is still an important gaming benchmark, but it should not be the only number used to judge a PC. 1% low FPS adds context about the slower part of the run, helping separate headline performance from performance that stays consistent in demanding moments.

If you are buying a new gaming PC, start with the games you play, resolution, monitor refresh rate, graphics settings, ray-tracing priorities, and any productivity work. That gives you a better foundation for choosing the right CPU, GPU, RAM, VRAM, cooling, and power delivery. If your requirements are specific, the Valhalla Custom PC Builder lets the system be planned around those targets from the beginning.

The Conqueror Series Thor is Valhalla’s gaming-focused path for high FPS and high-refresh performance, while the Elite Series Odin adds flagship 4K gaming and heavier productivity capability. You can compare more configurations in the Valhalla built-to-order gaming PC lineup.

1% LOW FPS FAQ

Common Questions About 1% Low FPS

Clear answers about 1% low FPS, average FPS, frametime, stutter, CPU and GPU bottlenecks, RAM, VRAM, FreeSync, G-SYNC, and frame generation.

1% low FPS is a benchmark metric that summarizes the slower portion of a gaming performance test. It is not simply the single lowest FPS result, and different benchmark tools can calculate the metric differently.

Its value is the extra context it adds to average FPS: a PC can have a strong average while still showing weaker slow-frame performance, which is one reason consistent performance matters when evaluating a high-end gaming PC.

No. Minimum FPS can be dominated by one unusually slow event, while 1% low summarizes a larger slow-end portion of the benchmark. The exact 1% low calculation still depends on the tool.

If you are troubleshooting your own system, first identify the hardware actually installed; checking your PC specs in Windows 11 gives you the CPU, GPU, RAM, storage, motherboard, BIOS, and driver information needed to interpret the result properly.

There is no universal good 1% low FPS number. A useful result depends on the game, resolution, settings, refresh rate, hardware, and benchmark method.

A demanding game at 4K, for example, should not be judged by the same raw FPS target as competitive lower-resolution gaming, which is why 4K gaming PCs need to be matched to a much heavier graphics workload.

Yes, when memory capacity, configuration, or stability is actually limiting the workload. The effect is most relevant in CPU-sensitive situations or when the PC is short on usable system memory.

Capacity is only part of the picture because RAM configuration, DIMM layout, memory profiles, and stability can also influence how consistently a gaming PC performs.

No—not at the rendering level. FreeSync and G-SYNC can reduce tearing and make normal FPS variation look smoother, but they do not make a genuinely slow CPU or GPU frame render faster.

That is why screen tearing and display-synchronization problems should be treated separately from CPU, GPU, shader, or engine-related rendering hitches that can weaken 1% lows.

Generally, yes, when you are comparing the same game, scene, settings, hardware, and benchmark method. A higher 1% low means the slower portion measured by that test performed better.

The right target still depends on resolution, refresh rate, and the games being played, which is why planning a built-to-order gaming PC around the intended performance target is more useful than chasing one universal 1% low number.

0.1% low focuses on a smaller and more extreme portion of slow frame delivery than 1% low. It can help expose severe hitches, but it is also more sensitive to short test runs and unusual events.

Because driver changes can also affect game behavior, keeping gaming PC drivers and software conditions consistent makes low-FPS comparisons easier to interpret.

Average FPS blends the entire test into one number, so a smaller number of slow frames can be hidden by many fast ones. CPU limits, GPU load, shader compilation, asset streaming, memory pressure, background software, or game-engine behavior can all contribute.

If the slowdown changes with CPU or GPU load, checking whether the CPU or GPU is the real bottleneck can narrow the cause, while hitches tied to asset loading should be interpreted alongside what a gaming PC SSD can and cannot improve.

Yes, when a game’s graphics-memory demand exceeds what the available VRAM can handle efficiently. Higher resolution, ray tracing, and high-resolution textures can increase that demand and may contribute to stutter or reduced performance when memory pressure becomes a real limit.

A high allocation number alone does not prove a bottleneck, so VRAM requirements for 1080p, 1440p, 4K, and ray-traced gaming should be judged against the actual workload rather than one memory reading.

It can change the reported result depending on what the benchmark tool measures. Frame generation adds generated frames to the displayed sequence, so displayed frame rate can rise without the game engine producing application frames at that same rate.

For a fair comparison, keep the same frame-generation mode and measurement method because frame generation changes displayed smoothness differently from underlying rendered performance.
