QualitySettings.asyncUploadBufferSize

説明

Asynchronous texture and mesh data upload provides timesliced async texture and mesh data upload on the render thread with tight control over memory and timeslicing. There are no allocations except for the ones which driver has to do. To read data and upload texture and mesh data, Unity re-uses a ringbuffer whose size can be controlled.

Use asyncUploadBufferSize to set the buffer size for asynchronous texture and mesh data uploads. The minimum value is 2 megabytes and the maximum value is 2047 megabytes. The buffer resizes automatically to fit the largest texture currently loading. To avoid a buffer resize (which can use extra system resources) set this value to the size of the largest texture in the Scene. If you have issues with excessive memory usage, you may need to reduce the value of this buffer or disable asyncUploadPersistentBuffer. Memory fragmentation can occur if you choose the latter option.

        // Set Ring Buffer Size to 16 MB.
        QualitySettings.asyncUploadBufferSize = 16;
    }
