So, you’ve built or bought a powerful gaming PC, but how does it really perform? Maybe you’re considering an upgrade and want to measure the impact, or perhaps you’re troubleshooting performance issues. This is where benchmarking your gaming PC comes in – the process of systematically testing your hardware’s performance under specific, controlled conditions.
Understanding how to benchmark your gaming PC provides objective data, moving beyond subjective feel. This guide from MTI Software will cover the essential benchmark software, recommended benchmark settings, methodology, and crucially, how to interpret benchmark results like FPS and frame times.
Types of Benchmarks: Synthetic vs. Real-World (In-Game)
Benchmarks generally fall into two categories:
Synthetic Benchmarks
These are specialized PC benchmark software applications designed specifically to stress components like the GPU or CPU in a highly repeatable and measurable way.
- Examples: Popular choices include 3DMark (with tests like Time Spy for DX12, Port Royal for ray tracing), Unigine Heaven or Unigine Superposition (GPU stress tests), and Cinebench (primarily CPU rendering performance).
- Pros: Excellent for direct hardware comparisons (e.g., comparing two different GPUs), testing system stability (especially after overclocking), and getting a standardized score. Highly repeatable results.
- Cons: Scores might not perfectly correlate to performance in every single game, as games utilize hardware differently.
Real-World (In-Game) Benchmarks
This involves measuring performance while running actual games, providing a more direct picture of your real-world gaming experience.
- Methods:
- Built-in Game Benchmarks: Many modern titles (Cyberpunk 2077, Shadow of the Tomb Raider, Forza Horizon 5, etc.) include an automated benchmark mode that runs a pre-defined scene. These are easy to use and repeatable within that specific game.
- Manual Gameplay Testing: Playing a specific, demanding segment of a game yourself while recording performance data using monitoring software. This requires more effort to ensure repeatability (e.g., running the exact same path/actions) but can test sections not covered by built-in tools.
Essential Benchmarking Software & Tools
To run benchmarks effectively, especially in-game tests, you need software to display and log performance data.
Performance Monitoring & Recording
- MSI Afterburner with RivaTuner Statistics Server (RTSS): This free combination is widely considered the gold standard for PC gamers. Afterburner monitors hardware (GPU/CPU temps, usage, clocks), while RTSS provides a highly customizable On-Screen Display (OSD) to show metrics like FPS, frame time, CPU/GPU usage, temperatures, and much more in real-time. Crucially, it can also log this data to a file for later analysis. This is the recommended tool.
- NVIDIA GeForce Experience / AMD Radeon Software: Both GPU vendors offer built-in overlays that can display basic performance metrics (FPS, usage). They are simpler to use but less configurable than Afterburner/RTSS.
- HWiNFO64: A detailed system monitoring tool. Excellent for logging comprehensive sensor data (temperatures, clock speeds, power draw, voltages) alongside your benchmarks to check for thermal throttling or power issues.
- CapFrameX / OCAT: More specialized tools focused on capturing and analyzing detailed frame time data, often used by reviewers for in-depth analysis.
Benchmark Suites (Synthetic)
As mentioned earlier, 3DMark and Unigine Heaven/Superposition are key tools for synthetic GPU testing. Cinebench remains popular for CPU testing. Many have free basic versions available alongside paid editions with more features/tests.
Setting Up Your Benchmark Run: Consistency is Key
Meaningful benchmarks require consistent methodology.
Prepare Your System
- Close all unnecessary background applications (web browsers, chat apps, launchers not needed for the game).
- Ensure your GPU drivers and Windows are up-to-date.
- Let your PC idle for a few minutes to reach a stable baseline temperature before starting.
- Use consistent power plan settings (e.g., High Performance).
Choose Your Game/Software & Settings
- Select the synthetic test preset or game(s) you wish to evaluate.
- Define and document the EXACT graphics settings: This is critical for comparisons. Note down:
- Resolution (1080p, 1440p, 4K)
- Overall Graphics Preset (Low, Medium, High, Ultra) OR specific individual settings if using custom.
- Ray Tracing (On/Off, Level)
- Upscaling (DLSS/FSR/XeSS – Off, Quality, Balanced, Performance)
- V-Sync: MUST BE DISABLED to measure uncapped performance.
- Frame Rate Caps: MUST BE DISABLED or set much higher than expected performance.
Choose Your Test Scene/Method
- In-Game Built-in: Use the game’s dedicated benchmark tool if available. Run it 3-5 times and average the results.
- Manual Gameplay: Select a specific, graphically demanding, and highly repeatable gameplay segment (e.g., walking a set path in an open world, a specific combat encounter start). Play this segment for a fixed duration (e.g., 60 seconds) multiple times (3-5).
- Synthetic: Run the selected test preset (e.g., Time Spy default). Run it 2-3 times.
Running the Benchmark & Recording Data
- Launch your monitoring software OSD (e.g., MSI Afterburner/RTSS). Configure it to show essential metrics (FPS, Frame time, 1% Low FPS, 0.1% Low FPS, GPU Temp/Usage, CPU Temp/Usage).
- Start data logging in your chosen tool (e.g., Afterburner’s logging feature).
- Execute the benchmark run (synthetic test or your repeatable in-game sequence).
- Repeat the run 3-5 times for consistency.
- Stop data logging after the final run.
Interpreting the Results: Beyond Average FPS
Raw numbers need context. Here’s what to look at:
Average FPS (Frames Per Second)
The most common metric, representing the overall performance across the benchmark run. Higher is generally better. Useful for a quick comparison, but doesn’t tell the whole story about smoothness.
Minimum FPS (1% Lows & 0.1% Lows)
These metrics are crucial for understanding perceived smoothness and identifying stutters.
- 1% Low FPS: Represents the average frame rate of the slowest 1% of frames rendered during the test. A value close to the average FPS indicates consistent performance. Large drops signal noticeable stuttering.
- 0.1% Low FPS: Similar, but represents the average of the slowest 0.1% of frames – highlights the most severe stutters.
- These are often more indicative of perceived smoothness than average FPS alone.
Frame Times
This measures the time (in milliseconds, ms) it takes to render each individual frame (FPS = 1000 / frame time). Consistent, low frame times result in smooth gameplay. Large spikes or variations in the frame time graph (viewable in Afterburner logs or tools like CapFrameX) correspond directly to visible stutters, even if the average FPS is high. Analyzing frame time consistency provides the deepest insight into smoothness.
Component Usage & Thermals
Check the logs:
- GPU Usage: Ideally, this should be consistently high (95-100%) during a graphically demanding benchmark, indicating the GPU is the primary bottleneck and working fully.
- CPU Usage: If CPU usage is very high while GPU usage is significantly below ~95%, you might have a CPU bottleneck for that game/setting/resolution.
- Temperatures: Ensure CPU and GPU temperatures remained within safe operating limits (generally below 85-90°C, check specific component limits). High temps can cause thermal throttling, reducing performance.
Comparing Your Results
Contextualize your numbers by comparing them to:
- Online benchmark results from reputable reviewers (ensure you match game, settings, resolution, and hardware closely).
- Your own previous results (e.g., before/after a driver update, overclock, or hardware change). This is the most valuable comparison.
Conclusion
Benchmarking your gaming PC is an essential skill for any enthusiast using PC benchmark software and consistent benchmark settings. It provides objective data to understand your hardware’s capabilities, measure FPS effectively, identify bottlenecks, test stability, and make informed decisions about upgrades or settings adjustments.
By moving beyond just average FPS and learning to interpret benchmark results like 1% lows and frame times using tools like MSI Afterburner, you gain a much deeper understanding of your system’s real-world gaming performance. Use this knowledge to fine-tune your settings and maximize your gaming experience!
