Unity FPS Estimator - Calculate Frames Per Second

Why is calculating FPS important?

Smooth experience: 60 FPS on PC, 30-60 on mobile is the quality standard
Competitive edge: Games with better performance attract more users
Proactive optimization: Identify bottlenecks before they affect users
Feature planning: Know how many effects/polygons you can add without losing performance

Target Platform Select your target platform. This will update recommended values.

Screen Width (pixels) Horizontal resolution

Screen Height (pixels) Vertical resolution

Visible Triangles Triangles per frame (in millions, divide by 1M)

Draw Calls per Frame Less is better. Target: < 1000 on mobile, < 2000 on PC

Active Visual Effects

Post-processing

Dynamic lights

Real-time shadows

Reflections (SSR/Planar)

Particle system

Volumetric effects

Each effect reduces FPS. See the approximate impact below.

Shader Complexity Higher complexity = more operations per pixel

Target FPS How many FPS do you want to maintain consistently?

frames per second

EXCELLENT

Optimal performance

0 ms

per frame

utilization

Excellent > 90 FPS

Good 60-90 FPS

Acceptable 30-60 FPS

Poor < 30 FPS

Reduce Draw Calls: Use material batching, texture atlases, GPU instancing
Optimize Geometry: Implement LOD (Level of Detail), culling, mesh simplification
Efficient Shaders: Use forward rendering for few lights, deferred for many
Post-processing: Half-resolution or quarter-resolution for heavy effects
Dynamic Shadows: Limit distance, reduce cascades, use shadow atlasing
Profiling: Use Unity Profiler (CPU/GPU) to find real bottlenecks
Targeting: Different configs for different devices/platforms
