Most modern graphics cards support the GPU pipe for Continuum. If you’re finding that Continuum is slowing down on your system when working with 4k or larger clips then this might be an indicator that the GPU can’t process that image size and is falling back to the slower CPU path. In this case you may need a graphics card with more available memory or you may need to close out other applications that are pulling GPU memory from the graphics card. Some hosts offer an option for the user to control how much memory is consumed when running that host so in these cases you may want to reduce the available memory in the host application to see if this helps with the GPU performance.
