When launching Mari 3.3v1 for the first time, you may see a warning that your Graphics Card driver is older than the recommended minimum version and this may impact the performance of Mari. The recommended minimum driver version is required to use Mari's new Parallel Shader Compilation functionality.
This article explains more about the graphics driver requirements and what to do if you cannot update your drivers.
More information about the different Shader Compilation modes is available in the following article:
Q100308: Understanding Mari 3.3's new Shade Compilation modes
In order to use the Shader Compilation 'Automatic' mode, you will need to meet the minimum requirements set for the operating system you are currently using.
If you do not meet these requirements then Mari will display a warning message like the images below.
NOTE: The minimum driver version is different for Windows and Linux.
Fig 1: Windows Driver Dialog - Minimum 368.39
Fig 2: Linux Driver Dialog - Minimum 367.27
If you would like to make use of Mari's new Shader Compilation modes, you should upgrade your NVidia drivers in order to meet the recommended minimum requirements and relaunch Mari. If you have successfully updated your drivers, you should not see the dialog window appear.
If you do not wish to update your drivers and would like to continue using Mari, we suggest navigating to your Mari preferences and changing your Shader Compilation mode to Legacy which will allow you to run Mari 3.3v1 in the same compilation method as in previous versions of Mari. With these older driver versions, you will still be able to make use of 3.3v1's other new features such as the Marquee Lift action and you will still experience optimisations in GPU texture management and an improvement in colorspace export speeds.
If you are experiencing other performance issues there are further settings or options that can be turned off to improve Mari’s efficiency. A detailed article about additional causes to consider is found here: Q100253: Troubleshooting Mari performance issues
