Hey there,
Maybe someone can help or can share some experience..
It´s look like there is a problem with outputing in Reso.
Whats wrong with the sending data from primary (rendering) card to expansion card like BM quad, another GTX, etc.? Why is there a huge performance drop?
There is no bottleneck. Main GPU is running on 45 - 50%, there is no reading problem of data from disk, no problem with amount of RAM, processor is runnig on 10%, PCI-E lines are ok and enough. And speed of PCI-E is crazy, there is no problem with bandwith in x16 gen3 or x8 gen 2 (case of BM Q2).
So why is there fps drop from 60fps to 25 fps when activating all of the outputs??
THX..
Edit: Same thing when using just one card and outputing, let´s say 2 x 4K and 1 x 3840 x 1080.
One wide composition and one layer. No effects, just playing one file, in DXV3. Same thing. Whole computer is resting and fps drops to halve.. Windows power scheme and nvidia control panel is prefering maximum performance, PCI-E runs on x16 gen3. So, what´s wrong?
I didn´t tryed it yet, but I believe, that if I will use just mosaic setup in windows, and play one video acros all of screens (let´s say 3x 4K), there will be no problem, no stuttering or dropping fps, same like just connecting 3 x 4K monitors and running screensaver on all of them..
Edit2: Next strange thing. I have completely clear deck. No videos in here.. Just wide composition like 19200x1080 on 60fps. With disabled outputs the counter says that it´s runing on 60fps. When enabling outputs, everything goes down. No footages, no pictures, nothing in deck. There is no reason for this huge drop.
So. Resolume is delivering 30-35 frames per second of nothing, instead of 60 frames per second of nothing to outputs, using 40% of graphic card performance (by GPU-Z).
I can imagine, that there is some allocation, but why Reso doesn´t use 80% - 100% of graphic card performance to delivering maximum fps to outputs (no matter if some footages or for delivering nothing)??
Edit3: And finally, there is really little difference between GTX 1070 and GTX 1080ti in that problem. Fps drop is maybe 5-7fps bigger in case of 1070..
