FPS Calculator: Estimate Your Gaming Frame Rate
Select your CPU, GPU, resolution, and quality preset to see estimated frame rates across ten popular games, from competitive shooters to demanding open-world titles.
How This FPS Calculator Works
Each game below is rated as CPU-heavy, GPU-heavy, or balanced, based on which component it leans on more. Your estimate blends your CPU and GPU capacity according to that weighting, then adjusts for your selected resolution and quality preset. A competitive shooter like CS2 leans heavily on the CPU; a visually demanding title like Alan Wake 2 leans heavily on the GPU. This is why the same hardware can show very different relative performance across the game list.
Why Your Real FPS Might Differ
These are estimates, not lab measurements. A few things this calculator can’t fully account for:
- Your specific driver version and game patch level
- Background applications competing for CPU or GPU resources
- Thermal throttling if cooling is inadequate
- In-game settings beyond the general quality preset (individual sliders vary by title)
- Upscaling technology (DLSS, FSR, XeSS), which this estimate doesn’t model directly
For the full explanation of how scores are calculated across this site, see our Methodology page.
Average FPS vs 1% Lows
The average FPS figure is the headline number, but it’s not the whole picture. Your 1% lows — the frame rate during the roughest 1% of frames — matter more for how smooth a game actually feels. Two systems with identical average FPS can feel very different if one has much worse 1% lows, which usually points to a CPU or RAM limitation rather than the GPU. If a game feels stuttery despite a healthy average FPS number, check our RAM bottleneck guide and CPU bottleneck guide.
How Resolution Affects FPS
Moving from 1080p to 1440p to 4K roughly doubles, then nearly quadruples, the number of pixels your GPU has to render per frame. This is why FPS drops significantly at higher resolutions even with an identical CPU — the GPU is doing dramatically more work. Lower resolutions shift more of the performance ceiling onto the CPU instead, which is why competitive players chasing very high frame rates often prefer 1080p even with a powerful GPU.
Frequently Asked Questions
How accurate is this FPS calculator?
It’s a relative estimate based on your component’s benchmark scores and typical game engine behavior, not a measurement from your exact system. Treat it as a starting point for comparison, not a guarantee.
Why does my actual FPS differ from the estimate?
Driver versions, specific in-game settings, background software, and thermal conditions all affect real-world FPS in ways a general estimate can’t capture. Your mileage will vary, sometimes significantly.
Does upscaling like DLSS change these numbers?
Yes, substantially — but this calculator doesn’t model upscaling directly. Enabling DLSS, FSR, or XeSS in a supported game will generally push your real FPS higher than the native-resolution estimate shown here.
Should I trust average FPS or 1% lows more?
1% lows are usually the better indicator of how smooth a game will actually feel, since they reflect the worst moments rather than the overall average.
Why do some games show much higher FPS than others on the same hardware?
Game engines vary enormously in how demanding they are and which component they stress more. A competitive shooter optimized for high frame rates will always show higher numbers than a graphically dense open-world title, regardless of your hardware.
Can I check for a bottleneck instead of just FPS?
Yes — run the same CPU and GPU through our bottleneck calculator to see which component is actually limiting your system, not just what FPS to expect.
