Rendering Frame Time Budget
Plan available milliseconds per frame and remaining budget after a measured stage.
Your inputs
Calculation results
Formula & assumptions
Frame budget = 1000/FPS; negative remainder means the stage alone exceeds target.
Values use the specified units. Calculations use floating-point arithmetic. Check input measurements and formula assumptions before applying the result.
Compare your scenarios
Save up to five results to compare changes side by side. Scenarios stay in this tab until you clear or reload it.
Using Rendering Frame Time Budget
Plan available milliseconds per frame and remaining budget after a measured stage.
- Enter target fps, stage time using the units printed under each field.
- Choose Calculate, or enable live updates. Review the result labels and formula assumptions.
- Save scenarios to compare up to five variations, then copy the report or download JSON or CSV.
Example
Target FPS: 60 frames per second Stage time: 8 milliseconds Frame budget · milliseconds: 16.666667 Remaining budget · milliseconds: 8.6666667 Stage fraction of budget · percent: 48
Questions & answers
What does Rendering Frame Time Budget calculate?
Plan available milliseconds per frame and remaining budget after a measured stage.
Which units should I enter?
Target FPS uses frames per second. Stage time uses milliseconds. Convert values to these units before calculating.
Which formula does it use?
Frame budget = 1000/FPS; negative remainder means the stage alone exceeds target.
What does the included example show?
Target FPS: 60 frames per second; Stage time: 8 milliseconds. Result: Frame budget · milliseconds = 16.666667; Remaining budget · milliseconds = 8.6666667; Stage fraction of budget · percent = 48.
Can I compare different settings?
Yes. Save a scenario, change the inputs and save another result. Up to five scenarios are compared in this tab; they disappear when you reload or leave.
Can I export the calculation?
Copy the JSON report or download JSON and CSV with inputs, result labels and numeric values. Processing uses local JavaScript; no calculation request is sent to our server. Displayed values use up to 10 significant digits; exports retain JavaScript numeric precision.
