CapFrameX enhances PC game benchmarking by measuring frametimes and percentile metrics, offering insights into gameplay smoothness.
Core Metrics and Setup
CapFrameX records per-frame frametimes in milliseconds and converts them into frames per second (FPS), providing key metrics: average FPS, 1% low FPS, and 0.1% low FPS. These metrics expose performance dips and stutters often overlooked by average FPS alone. Accurate benchmarking starts with updated systems; UEFI/BIOS, operating systems, and drivers must be current.
Preparation is crucial: disable unnecessary apps and overlays, turn off V-Sync and latency-reducing features like NVIDIA Reflex. Ensure high-performance settings and consistent conditions by using identical graphics settings and repeatable scenes for each run. Run benchmarks multiple times—at least three—to mitigate variance, leveraging CapFrameX's data aggregation features for comprehensive analysis.
Capturing and Analyzing Benchmarks
Install CapFrameX via GitHub Releases, with an optional RivaTuner Statistics Server for overlays. Configure the capture directory, timing, and hotkeys on the first run. Use a reproducible game scene and set Capture Time to zero for manual oversight. Aggregation tools within CapFrameX allow for merging runs and handling outliers. Analyze captures within the Analysis tab to examine frametime graphs and percentile metrics.
For enhanced analysis, use CapFrameX with compatible power measurement devices to track power, voltage, and thermal data accurately. Avoid common pitfalls: ensure consistent conditions and use multiple runs for statistical reliability. Proper benchmarking aids in understanding real game performance, assisting in more informed tuning and hardware decisions.
Market Impact and Adoption
CapFrameX addresses the growing need for precise performance metrics in the gaming industry. As PC gaming continues to evolve, tools that provide percentile-based insights become critical. By offering comprehensive performance analysis, CapFrameX empowers users to make data-driven adjustments, increasing the efficiency and enjoyment of their gaming experiences.
