The DeepPRIME Acceleration menu lets you select between manually managing the use of a graphics card (GPU) or the CPU for calculations and image processing or allowing DxO DeepPRIME to choose this for you in 'auto' mode.
Please verify that you have installed the latest drivers for your graphic card. To do this, please update from the website of your graphics card manufacturer, just checking for Windows Updates is not reliable at this point.
