1. see CPU Occupy Top function , Analyze and optimize from high to low .
2. see GC Occupy Top function ,GC Is the main reason for most of the catons .
3. Look at the performance loss caused by the script .
4. Reduce the rendering resolution of the game , When the frame rate of the mobile phone is low , Reduce the number of pixels to be processed per frame .

ReservedMono Peak value (MB)

Project runtime Mono Managed heap memory managed and allocated .

Recommended values < 80 MB

UPR Optimization Suggestions
Unity The memory in the project is mainly occupied by static resources 、AssetBundle and Mono Heap memory consists of .

1. Use UPR The resource detection tool detects project resources . Check whether the memory usage of resources is reasonable , And whether there is the problem of resource redundancy .
2. see Mono Rationality of heap memory usage ：ReservedMono Whether the peak exceeds UPR Recommended values ,ReservedMono Whether there is a continuous upward trend .
3. Mono The usage of heap memory mainly comes from reading and parsing configuration files , Check the rationality of heap memory usage for configuration file read operations .
4. see AssetBundle The presence in memory .

Peak value of texture resource .

Recommended values < 50 MB
UPR Optimization Suggestions
There are three main factors that determine the size of texture resources ： The resolution of the 、 Format and Mipmap Open or not .

1. Reduce resolution , according to Game When the camera is closest to the object , The maximum resolution is determined by the pixel size occupied by the object .
2. Split the transparent channel (Alpha), Because the belt Alpha Channel mapping Unity Will default to RGBA Format .
3. Adjust the compression format , Try to use the highest compression format supported by the current platform .
4. Ban Mipmap.
5. Enable Use Crunch Compression,Crunch yes Unity Latest supported compression formats , The compression ratio is very high .

Recommended UPR The resource detection tool detects project resources .

Peak value of grid resources .

Recommended values < 20 MB
UPR Optimization Suggestions

1. Reduce vertices , On the premise that the artistic effect can be realized , The fewer vertices the better .
2. Turn on Optimize Mesh Options .
   Recommended UPR The resource detection tool detects project resources .

The peak of animation resources .

Recommended values < 15 MB
UPR Optimization Suggestions

1. Reduce the animation length .
2. Reduce the number of bones , Delete invalid bone points .
3. Reduce keyframe density , And reduce imported redundant keyframes .
4. Reduce animation accuracy , Reduce animation size .
   Recommended UPR The resource detection tool detects project resources .

Draw Call Peak value .

Windows Terminal Draw Call The value may be too high , Please refer to the value on the mobile phone .

Recommended values < 250( Time )
UPR Optimization Suggestions

Use WinUpr To test , And record RenderDoc, coordination RenderDoc Graphics debugger , Perform graphics performance tuning .

1. UI DrawCall It is suggested that the quantity should be limited to 15-40 Between ,UI DrawCall Too much or too little , Will increase the consumption of performance .
2. View the of the rendered object DrawCall Whether the batch is correct .

Tris Peak value ( Noodles )

Recommended values < 200000( Noodles )

UPR Optimization Suggestions

1. Check the rationality of the number of meshes it renders .
2. Step up to Game Object The cutting force .
3. Simplify the scene mesh .

Section details – Performance overview – CPU details :

Camera Render The average time taken

Recommended values No more than 15ms Frame ratio of > 95%

UPR Optimization Suggestions

stay "CPU > Function performance " On the page , see Camera.Render Performance details , It helps to quickly locate the performance bottleneck of the rendering module .

Shader CreateGPUProgram The average time taken

Recommended values < 20(ms)

UPR Optimization Suggestions

Recommended UPR The resource detection tool detects project resources .
see Shader Is there a problem of resource redundancy , The problem of repeated parsing should be avoided .

Section details – Performance overview – Memory details :

ReservedUnity Peak value

by Unity Memory allocation required by the engine's own logic , Including the memory occupation of each module management class , Serializing information 、WebStream、 Memory occupation of resources, etc .

Recommended values < 150(MB)

UPR Optimization Suggestions

1. Check if there is AssetBundle Not cleaned up .
2. Assetbundle When packing , If there is only one reference, it will not be set AssetbundleName. Reduce Assetbundle Number of documents .
3. Use SerializedFile load Assetbundle After that , instant Unload.
4. For occupancy WebStream The larger AssetBundle file , Use LoadFromCacheOrDownLoad or CreateFromFile To replace , About to unzip AssetBundle The data is stored locally Cache For use in .
5. Analyze texture 、 The Internet 、 Animation 、 Memory consumption and performance bottleneck of resources such as audio and materials , Targeted optimization .

ReservedMono Peak value

Project runtime Mono Managed heap memory managed and allocated . For the vast majority based on Unity For engine development projects , except iOS Outside the platform , Its managed heap memory is composed of Mono Assigned and managed .

Recommended values < 80(MB)
