GPUSight – Find Rendering & Shader Performance Bottlenecks

Stop guessing what to optimize. Find rendering bottlenecks in Unity with scene maps, grouped workload, object and shader research, material benchmarks, frame timing, built-in profiles and snapshots.

REQUIREMENTS

• Unity 2022.3 or newer.

• Built-in / URP 14+ / HDRP 14+

Stop guessing what to optimize.

GPUSight helps Unity developers find rendering hotspots, understand the evidence behind them, and check whether an optimization changed the workload.

SEE THE BIG PICTURE

• Find areas worth investigating directly in Scene View with visual workload maps.

• Explore geometry workload, coverage, opaque and transparent overdraw, transparency, available shader passes, shadow-casting settings, shader features and texture resources.

• Switch between maps to investigate different aspects of the same scene, then follow the findings into individual objects and materials.

• Start with an overview of available GPU-pressure and workload signals.

BREAK DOWN THE WORKLOAD

• Group and filter contributors by material, shader, pass, camera, scene, layer, tag or prefab.

• Identify heavy groups, then inspect the contributing objects, geometry, materials, shaders and textures.

• Navigate from a contributor to its scene selection, Inspector and material research.

INVESTIGATE GEOMETRY AND LODS

• Use LOD coverage maps to find objects without LODGroups and inspect the levels available across your scene.

• Explore estimated LOD levels and triangle reduction between levels to spot transitions that deserve attention.

• Inspect an object’s geometry and LOD configuration alongside its contribution to the workload.

INSPECT TEXTURES AND TEXEL DENSITY

• Explore texel-density, mip-demand and texel-outlier maps to find texture-density differences in the current view.

• Use a visual texel grid to compare texture scale across surfaces.

• Inspect material texture bindings, dimensions and available resource-allocation data.

RESEARCH SHADERS AND VARIANTS

• Review material settings and static shader-source indicators for texture sampling, math, loops, branches and vertex processing.

• Inspect selected shader variants and explore function-level source metrics.

• Compare variant configurations to understand how keywords and other settings change the source-analysis results.

BENCHMARK AND COMPARE MATERIALS

• Run controlled material and shader benchmarks with their test conditions visible.

• Compare material configurations A/B and review both configuration differences and measured preview timings.

• Test how preview timings change with resolution, draw count and geometry.

• Keep a baseline and export benchmark reports for later review.

MEASURE FRAME TIMES AND SPIKES

• Record available CPU and GPU frame timings in Play Mode and inspect slow frames.

• Review frame-time history, spike markers and P95/P99 statistics to investigate performance stability.

• Set budgets with built-in or custom performance profiles and check timing results against your targets.

SAVE, COMPARE AND SHARE

• Save snapshots of the available analysis results and their context.

• Compare compatible results before and after an optimization.

• Export and import snapshot JSON to preserve findings and share them with your team.

For solo developers, technical artists and game teams, from a first performance pass to deeper rendering investigation.
