What are Optimus graphics?
"NVIDIA Optimus" is the brand name for an NVIDIA implementation of dual-GPU switching in machines. Optimus is found in many modern machines that include both Intel integrated GPUs and NVIDIA discrete GPUS, and is intended to run powerful discrete GPUs only when needed, automatically, without prompting the user.
What are switchable graphics?
More generally, "switchable graphics" is often used to refer to the graphics, regardless of brand, in any computer where two GPUs, one low-power and one high-performance, are present and can be alternated between.
How does CloudReady handle switchable graphics?
In past versions of CloudReady, starting with v61, switchable graphics caused unexpected issues ranging from a failure to install to crashing to performance degradation. Starting in v68 of CloudReady, better support exists to prevent these issues.
Note that, though CloudReady should prevent any issues related to switchable graphics, it does not support dynamic switching between multiple GPUs the way Windows, MacOS, or Linux may. Regardless of any settings,CloudReady will select a single GPU from those that are available and use that 100% of the time.
In some rare cases, a certified CloudReady model may come in variants where not all GPU options are supported, including one of two switchable graphics options in some cases. In those situations, we make a note on the model's details linked on the certified list to make clear which GPUs are supported and any necessary settings.
- You can usually find settings to control these features, if available, in your device's BIOS/UEFI menus like "Video", "Graphics", or "Advanced". These settings may allow you to target the specific GPU you prefer instead of leaving it up to CloudReady.
- If you prefer longer battery life or lower power use, you should target entries that include terms like "integrated" or "intel". Neverware recommends these options, as CloudReady is designed to minimize the strain on hardware and perform well even on lower powered graphics.
- If you prefer maximum graphics performance, select "discrete", "Nvidia", "ATI", or "AMD" entries
- If you look for settings of this kind and do not find any, your model(s) may not have this feature. Unless you experience crashing or issues, don't worry.
- If you are presented with multiple settings of this kind, you may need to experiment with different combinations of settings to see what works best for you.
