The System section allows you to set graphics card options, memory limits & sound settings.
If your hardware does not support some of the options described on this page, then they will either not show up or be corrected on startup.
Cycles Render Device
When set to None or when the only option is None: the CPU will be used as the computing device for Cycles.
If the system has a compatible Nvidia CUDA device, it will show up an option for rendering with Cycles.
If the system has a compatible Nvidia OptiX device, it will show up an option for rendering with Cycles.
Caso o sistema possua um dispositivo compatível com OpenCL do fabricante AMD, ele será mostrado como uma opção para utilização na renderização através do motor de renderização Cycles.
- Distribute Memory Across Devices
Allocates resources across multiple GPUs rather than duplicating data, effectively freeing up space for larger scenes. Note that in order for this option to be available, the GPUs must be connected together with a high bandwidth communication protocol. Currently only NVLink on Nvidia GPUs is supported.
Memory & Limits
- Undo Steps
O número de passos para desfazer disponíveis.
- Undo Memory Limit
A utilização máxima de memória em Megabytes (Valor 0 (zero) significa ilimitado).
- Desfazer globalmente
This enables Blender to save actions done when you are not in Edit Mode. For example, duplicating objects, changing panel settings or switching between modes.
While disabling this option does save memory, it stops the Adjust Last Operation panel from functioning, also preventing tool options from being changed in some cases. For typical usage, its best to keep this enabled.

- Console Scroll-back Lines
The number of lines, buffered in memory of the console window. Useful for debugging purposes and command-line rendering.
- Texture Time Out
Time since last access of a GL texture in seconds, after which it is freed. Set this to 0 to keep textures allocated.
- Garbage Collection Rate
Number of seconds between each run of the GL texture garbage collector.
- VBO Time Out
Time since last access of a GL vertex buffer object (VBO) in seconds after which it is freed (set to 0 to keep VBO allocated).
- Garbage Collection Rate
Number of seconds between each run of the GL vertex buffer object garbage collector.
Editor de sequências de vídeo
- Memory Cache Limit
Upper limit of the Video Sequencer and Movie Clip Editor memory cache (in megabytes). For an optimal Clip editor and Sequencer performance, high values are recommended.
- Use Disk Cache
Writes cached strips to disk which can store a lot more than RAM. To use the Disk Cache, this option must be enabled, the Disk Cache Directory and Disk Cache Limit set, then save or reopen the existing blend-file.
The location on disk to store the cache.
- Cache Limit
Upper limit of the Video Sequencer’s disk cache (in gigabytes), setting to zero disables disk cache.
The level of compression to compress image in the disk cache. This has a trade off between saving disk space and requiring more processing. The more compression used requires faster disk write/read speeds and more CPU usage.
- Proxy Setup
When and how Proxies are created.
Build proxies for added movie and image strips in each preview size.
Set up proxies manually.
This panel contains the sound settings for live playback within Blender and are only available with SDL or OpenAL. To control these settings for exporting sound see the Encoding Panel and Audio Panel.
- Dispositivo de áudio
Define o motor de áudio a ser usado para processar e gerar a saída de áudio.
Sem suporte a áudio (mesmo sem a saída de áudio, as faixas de áudio podem ser carregadas normalmente)
Uses Simple Direct Media Layer API from libsdl.org to render sounds directly to the sound device output. Very useful for Sequencer strips editing.
Provides buffered sound rendering with 3D/spatial support. Used for 3D source support by speaker objects.
Sets the audio channel count.
- Contingenciamento de mistura
Sets the number of samples used by the audio mixing buffer. Higher buffer sizes can cause latency issues, but if you hear clicks or other problems, try to increase the size.
- Taxa de amostragem
Sets the audio sampling rate.
- Formato de amostragem
Sets the audio sample format.
