hi there

thanx to bjoern and tonfilm I managed to patch a patch (?!) where I can scroll horizontal over a some pictures.

problem is now: I have a setup with 3 monitors (a dualhead 2go plus a secondary output on my graphicscard (radeon x1650 agp) I have 2 renderers, one (1024x768) on the secondary output monitor and one (2048x768) on the dualhead.

if I have them both on the dualhead part of my monitors, the performance is great, no problem, but if I put the small renderer on the secondary output monitor the performance is bad, and I do not even have it fullscreen!

I dont really get this, is there a solution or should i just by a triplehead2go?

my patch is in the attachment, could somebody please have another look at this?

thanx a lot

just to let you know

I just scaled up my textures to 1024x1024 (read somewhere that that would help the performance) but it is not that big a difference

does the perfomance remain bad if you have it fullscreen?

the big renderer: no problem
the small renderer: doesnt even appear, the screen stays black

as soon as you have two renderer on two outputs, it is all rendered twice, in bad cases this would be double memory use and double performance. so yes, buy a triplehead, having one renderer leads to best performance.

but i have seen some disconnected pins with spreads in it, and the GetSlice was getting the pictures just the same way as they are already in the spread. only difference was, that the first picture was put at the end again.

and there was a * 2 at the first transform, if you just want to have an offset to adjust the screen displacement, that would be a +.

jep the only difference is that the screendisplacement should be in the way that you get an continuous sight of the pictures

the a*2 does sort of the same as the a+. does.

i think there is no other way of getting that screendisplacement withoudt double-ing performance is there?

so then i should be off buying a triplehead

ah, i see what you mean, this is because of the different aspect of the screens. but vvvv has a professional solution for distributing one content over multiple screens using the MultiScreen and MultiViewport modules:
