⚡ FPS Performance Optimizer
Enter your frame rate and monitor refresh rate to see frame times, whether your GPU is feeding the panel fully, and how much headroom you have to cap or unlock.
🖥️ Match Frames to Refresh
What is an FPS Performance Optimizer?
It takes two numbers — your frame rate and your monitor's refresh rate — and turns them into the frame-time figures pros actually reason about, then tells you whether your GPU is matching the panel, falling short, or overshooting it. When it overshoots, capping the frame rate or moving to a higher-refresh monitor puts those extra frames to use.
Use it to decide whether to cap FPS, whether a 144Hz upgrade is worth it, or where to spend a settings budget. It's a deterministic guide, not a benchmark — real perceived smoothness also depends on frame pacing, VSync, and variable-refresh (G-Sync/FreeSync) support.
❓ Frequently Asked Questions
How does the FPS performance optimizer work?
It converts your frame rate into a frame time in milliseconds (1000 ÷ FPS) and does the same for your monitor's refresh rate, then compares the two. If your FPS meets or beats the refresh rate, the panel is fully fed; if it falls short, you're leaving smoothness on the table. It also reports the headroom — how many frames per second you're above or below the refresh rate.
What is frame time and why does it matter?
Frame time is how long each frame takes to render, in milliseconds. It's the inverse of frame rate: 144 FPS is about 6.94 ms per frame, while 60 FPS is 16.67 ms. Consistent, low frame times feel smoother than a high average FPS with occasional spikes — which is why stutter can be noticeable even when the average frame rate looks fine.
Should I cap my FPS to my monitor's refresh rate?
Often, yes. If your GPU pushes far more frames than the monitor can show, those extra frames are wasted — they add heat, power draw, and coil whine without visible benefit, and can introduce tearing. Capping FPS at (or just below) the refresh rate, especially with G-Sync/FreeSync, usually gives the cleanest, most efficient result.
My FPS is below my refresh rate — what can I do?
Lower demanding settings (shadows, ray tracing, and view distance are common culprits), drop the resolution or enable an upscaler, and close background apps. If you're consistently well under the refresh rate, a variable-refresh monitor helps by syncing the panel to your actual frame rate so the shortfall looks smoother.
