Resolume Forum

For a fixed installation, we are using a Lenovo P510 tower with 2x nVidia Quadro M2000 cards, each with 4 Displayports. We need to connect 4 or 5 projectors, so we need all the outputs. The system drive is an SSD and there is a large data drive that we use for footage. We do play show footage from the SSD.

It's working OK so far though we occasionally get jerky playback with very large files (3840 x 800 encoded using DXV3). Things will be playing at 60fps then suddenly it will drop to 2fps for a second or so.

Any thoughts or advice? I was thinking of adding a second SSD for playback files, so it doesn't share the system drive.

When troubleshooting stuff like this, it's always a good idea to use Task Manager to see if there's any spikes in activity when these drops happen.

By checking Resolume's disk and CPU usage as well as other app activity, you can narrow it down to a background process getting in the way, not enough disk read bandwidth, or something else.

It looks like there is a process called "Desktop Windows Manager" that kicks in and sucks CPU. When this happens Resolume framerate drops to 2fps from 60fps every few seconds.

I think we've dealt with it, we're now getting consistent 60fps at 3840 x 1280 with 4 outputs, which is what we want.
