Softedge - Flash Render

vvvv beta general

hi vvvvorum,
i am using softegde, multiscreen (spanmode) with a flash file for input.
renderer (flash) > gdi texture > multiscreen
i have some performance problems and wanted to ask if i am not seeing the point. my flash file has got the dimensions of 3320px x 800px (triplehead2go) and i am using a dual quad core @ 2,8 + 12gb ram + ati radeon hd 4800 series. when playing the flash file without softedge blending, there are no performance issues.
has anybody an idea, what could be the issue for the performance loss?
i saw, while screwing down the anti aliasing of the dx9 renderer to NONE the performance is much better… the renderer dx9 in debug mode is constantly at ca. 100.
i would be very happy about some more hints how the performance could be increased.

best regards, philipp.

hi phil203,

generally the performance bottle neck is with the GDI texture. GDI stuff is done on the CPU and even though your PC is fast 3320px x 800px every frame is a tonne for a processor to do.

got the dimensions of 3320px x 800px

I’m pretty sure the maximum flash stage size is 2880px so you’re wasting a little setting the backbuffer to 3320px but that aint going to make that much difference.

playing the flash file without softedge blending, there are no performance issues

I assume you mean no performance issues inside of the flash renderer. If so, this is because it’s playing through the flash ActiveX and there shouldn’t be any difference here than in a web browser for instance.

Check this thread out regarding a flash performance increase.
