Notebook Performance / Multiple GPUs

In case you want your Notebook to perform optimal with PLAYDECK, you might need to adjust some options.

Multiple GPUs

If you have multiple GPUs in your system, PLAYDECK doesnt know which one is the most potent and will always use the primary GPU of your System. To see, which GPU is recognized as primary within PLAYDECK, click “Settings > Workflow > Performance > Show GPUs”.

If your potent GPU is NOT listed as primary GPU, you are missing out on the best possible performance. A good scenario is a Notebook like the Razor Blade, which provides an onboard Intel GPU and a seperate dedicated NVidia GPU.

Please note, that decoding (of videos) will ALWAYS be done on the NVidia (if found) and afterwards the Intel (if found) – in this case it doesnt matter if the NVidia is primary or not. The primary GPU is only used for 3D/Rendering (Transcoding, Previews, Outputs, Streams,…).

Change the primary GPU

There are several ways to the another GPU as primary. You have to check, which applies to you:

  1. Open NVIDIA Control Panel, select “Manage 3D settings”. In the “Global Settings” Tab you set “Preferred graphics processor” to “High-performance NVIDIA processor”.
  2. Restart your PC and open the BIOS and deactivate your Onboard GPU or set the primary GPU to the dedicated PCIe slot.
  3. Reconnect your Monitor/Display device. During system boot, Windows may decide for you, which GPU is primary, if it has a monitor connected.
  4. Sometimes, especially on Notebooks, a specific driver/manufacturer software is required to change the primary GPU
  5. Starting with PLAYDECK 3.6 you are able to force using a specific GPU for 3D/rendering

If this doesnt work, your Notebook might not have a dedicated GPU Mode; some older Razer Notebooks for example dont support a Dedicated GPU Mode. There is nothing you can do then: The NVIDIA GPU needs to be the Primary GPU of the System, otherwise it cant be fully utilized by PLAYDECK.

Remote Desktop software

Another scenario is connecting to the system via Remote Desktop software. Some tool will create a new virtual GPU upon connection to handle the picture transfer. This interferes greatly with PLAYDECK and may to bad a performance, since the primay GPU is now the virutal GPU of the remote desktop software. In this case we recommend to only use remote desktop software, which DOES NOT interfere with the primary GPU. Currently AnyDesk or the native Windows RDP connections work flawless, while TeamViewer causes problems.

Reduce GPU/CPU usage

In case your PLAYDECK runs on an older Onboard GPU (Intel) or even on CPU alone, it might be difficult to get a good performance for dual HD output. To reduce GPU/CPU usage of PLAYDECK you have several options:

  1. Reduce overall Quality (and therefore CPU usage) in “Settings > Workflow > Performance”
  2. Prevent PLAYDECK from needing to transcode video clips during playback: Have videos in the same video format as the playlist
  3. Configure Windows Power Management for Maximum Performance or disable Energy Saving completly
  4. Ensure that all CPU cores are used (Check in Resource Monitor)
