System
The System pane of the Preferences window consists of a series of panels that configure the computer and other hardware that comprises your DaVinci Resolve workstation.
Memory and GPU
The top section of this panel provides Memory Configuration options, while the bottom section of this panel provides controls over how GPU processing is handled.
Memory Configuration
This section has the following preference settings handling memory usage.
— System Memory: The total available RAM on your workstation is listed here.
— Limit Resolve Memory Usage to: This preference limits the total amount of system memory that Resolve uses, keeping memory available for other applications. The maximum and default setting for this preference is 75 percent of your system’s RAM.
— Limit Fusion Memory Cache to: Lets you limit how much RAM the playback cache on the Fusion page is allowed to use. Depending on the length of clips you’re working on in the Fusion page, the playback cache can occupy a considerable amount of available memory. The amount you allocate here is taken from the total amount of memory allocated by the “Limit Resolve Memory Usage to” setting.
GPU Configuration
This section lets you choose how GPU processing should be handled.
