Output is 1920x1080 and is fed to datapath driving 4 1024x768 displays that crop the output to a 4x4 display configuration.
The composition to test is a ramp set to circular at resolution 1024 x 1024 8bit.
The phase is is controlled via constant to speed chop into the phase of the ramp.
When running this system on the laptop screen I get full performance.
On the datapath i get only a mere 25 fps. I disconnected the x4 used a
External Monitor on 1920x1080 everything looked fine again 60 fps.
Any idea’s about this.
What is a good solution to get 4 outputs? Extra graffic Card and two dualheads.
Or a matrox Card with 4 outputs or the new Ati cards with even 6 outputs.
I also found that controlling ramps via the phase or rotating top’s via a transform are very heavy on the system. Is there a reason why ? Or could my system by setup wrong.
There is nothing about the X4 that would tax your system more vs. another monitor of identical resolution, so a Matrox would be the same (and much harder to configure properly in our experience).
How many windows did you have open in TouchDesigner when you were running a test? Having more than one window rendering can impact performance.
Well I did some testing and found in the mixxa forum some settings I did not do before.
That is nvidea vsync off triple buffering on. That gave an inmence speed improvement ofcourse.
I do believe that there is something wrong or i’m doing wrong. Basically I generate content either using ramps that are driven by controlling the phase from a chop. Or use a sop network that is distorted after that I add a texture camera’s lights ect ect. The sop networks all run fine even the more complex ones. But the compositions that use the ramp and or a transform tops have problems. All my compositions with top’s accros different systems experiance a non constant playback speed. Is that because in top’s parameters are not timesliced ? And how can I solve this.
I attach example file that will look fine at first.
simple phase modulated ramp.
When looking more detailled you will see that the animation is not fluent.
Sometime there is a little delay. You have to play with the speed sometimes to really see it.
