Hi there,
Have a new "extreme" test system we put together in the shop to see how much we could push things a bit and having some interesting results.
Here's the specs:
Software: Resolume Arena 5.1.4
CPU: Intel Xeon E5-1620v4 (40 PCI-E lanes)
Motherboard: Gigabyte X99-UD3P
Ram: 32GB DDR4 (quad-channel)
GPU: EVGA GeForce GTX 1080ti Founders Edition 11GB
I/O: 3x BlackMagic DeckLink Quad2 SDI cards (24 outputs total)
Storage: 2x WD Blue 1TB SATA3 SSD in Raid-0 (can't spare the pci-e lanes for m.2 in this case)
OS: Windows 10 Home 64bit w/all updates (game mode disabled)
So, with all 3 of the Decklink Quad2 cards installed and 24-outs going from Resolume we get about 18fps at 720p60. I'm not really suprised, as it's a lot for the GPU to render and move across the PCI-E lanes (keep in mind all cards have the full 16x/8x lanes available because of the CPU).
However, when I check hardware managers I'm only seeing about 40-40% GPU usage, 25-40% CPU usage, and super low read-usage from the SSD RAID (though I find that sort of hard to believe as they are reading many separate DXV files).. is this all due to the bottle-neck of the GPU needing to move everything over the PCI-E lanes to the Decklink cards, or some sort of software bottleneck? I have gone through the usual Nvidia settings and set everything to max performance, vsync on or off doesn't seem to make much difference.
Interesting thing is, effects or resolume settings (such as "disable global effects") don't seem to make much difference. When only using 16-outputs the frame rate is about 35fps and turning on lots of effects only drops it to 33fps for example.
So, any input would be nice. For now I'll plan to only use 16 outs as that seems to be fine, but would be nice to use all 24!
thanks!
