Dear list,
just wanted to inform you that I managed to have 2x12 fullHD screens connected and controlled by GEM. With 2 Mac Pro and 6 Datapath x4 4K external graphic cards works smooth. It is not visible from the picture, but these squares are cubes, which revolves when someone gets into interaction with the motion sensors. The result is in the attachment:

No upscaling, no additional processor between the computer and the video wall. Just smooth 15840x3240 real time rendered pixels. Thanks for your ideas and help during the process.
Best:
Popesz

Hi Iohannes,
I just wanted to ask if according to you this approach is feasible with such a gemwin dimension [dimen 7680x3240(. And if a Mac Pro could handle it with 4-8 or 12 core processor.
I'm not very learned when it comes to apple, so I cannot give an authorative answer your question.
anyhow: the number of cores are probably not very relevant here, as most of the work is done by the GPU. a resolution of 7680x3240 does not seem very high for nowadays standards.
the maximum texture size (which is the relevant spec here) for modern cards should be at least 8192x8192 pixels (e.g. my intel gfx-card on my lenovo x230 supports 8192x8192; my quite old (~10 years) nvidia GeForce 7800GTX would support only 4096x4096; what i here from the new nvidia GTX980 it should have a maximum texture size of 65536x65536 pixels).
About the NVidia GTX980, what does it mean : Maximum Digital Resolution* : 5120x3200 ? this is on : http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-980/specificati ons ++
