I wanted to share what I’ve learned and progress we’ve made and get input from anyone else using Intuiface to power large video walls.
These tests were run on an Alienware Area 51 with 2 Gforce GTX 980 Ti cards.
Intuiface seems to be crippled when using display arrays powered by more than 1 video card. Video files and any image or object with position animation seemed to choke down to about 10 frames per second or less. (stutter effect)
After buying the display port adapters we needed to test using 1 video card instead of 2, the performance of 3 1080p videos running at the same time became acceptable and not stuttered. (scattered accross three 4K displays, all running in 1 player)… So this was nice progress… Here is a video of that test after adding 3 more videos. The video starts to stutter a little but with all thats going on (6 videos timelines sending actions to syncronize background images, text callouts and an image collection, it’s pretty impressive. - note this looks like a pile of crap because it’s not a real project- just a test I threw together.
*edit - how can I share links to videos in dropbox. The player its automatically adding here isn’t working (in Chrome on mac at least).
**edit - I commented out the link so copy and paste them (without the ///)

The test in this next video is a 6K video (scaled up to 12K in intuiface) playing accross three 4K displays. The question is, since Intuiface uses VLC’s playback engine (or a component from it?) why can VLC do this perfectly, but the same exact video in a blank Intuiface project is a problem. Where is the bottleneck and is there anyway to widen it?

Thanks for any thoughts or input.
