Hi everyone,
just wanted to share my experience with my e-GPU rig: a Portable MEDIA-SERVER for VJING and VIDEOMAPPING.. which is going great!
I'm running my visuals at 50-60fps constant with 4 layers of Full HD contents and one layer with a heavy ISF SHADER (GLSL for VDMX),
with lot of very heavy video filters and effects (all ISF and running on GPU),
outputting to 7 monitors with different resolutions (and each with different images):
A-laptop monitor (used only for the softwares controls and NOT for any video preview - it will slow down completely the machine)
B-external preview monitor (acer 1366x768 res)
C-3 outputs of 1024x768 from DVI-D to Matrox TripleHead2go
(in the picts outputting only to 1 monitor but is effectively outputting out all the 3 DVI ports - sorry didn't have enough monitors in the house!)
D-external monitor 1 (1920x1080)
E-external monitor 2 (1920x1200)
HARDWARE:
-MBP Late 2011, 16GB RAM, 256 SSD and 500GB HHD storage;
-Akitio Thunderbolt 2 PCIe + PCIE 16x16 Extender (powered);
-MSI GTX 970 (bypassed the voltage control of the fans straight to the PSU to be always at max speed);
-Cooler Master 500w PSU;
-used small PC box (un-named);
SOFTWARE (running)
-OSX El Capitan;
-VDMX (syphoning to Madmapper)
-MadMapper;
TO NOTICE:
-i've tested the e-GPU with newer Retina MBP from 2013 and 15 and they don't work as good, actually running faster with their own built-in graphic cards;
-i've daisy-chained an Elgato Thunderbolt dock with an external SSD USB 3.0 drive and it was working still fine (when reading videoclips form it was only dropping a few frames);
-daisy chained a BlackMagic Ultra-studio mini Recorder with 1920x1080 HDMI signal in to capture another video signal and was working still fine, but dropping more frames as
heavier the patch of VDMX and Madmapper is. For less stressing patches and setups i believe can run fine.
hope it helps,
Federico
