Renderer EX9 quite slow

vvvv beta question
1

hey guys,

i just upgraded from version 40beta22 to 45beta24.1 - ok it has been a long time :-). so now rendering a blank quad in the ex9 renderer causes a count of 1200-1400 ticks which is quite slow. in 40_22 it only takes 150 ticks. is this a known issue? i couldn’t find an anwer about that in the forum so that’s why i’m asking you.
what can i do to increase speed?

by the way i have already tried to solve this problem by updating my dx-redist.

thanks for your help,

simon

helo simon, sounds strange. what do you mean by “ticks”? how about beta23?

@joreg: see documentation about debug mode xD

does Renderer TTY say anything? does this happen on a different pc also?

Simon and I played around with different settings. the same problem occurs in beta_23. it works with a normal speed after changing the back buffer format from X8R8G8B8 to anything except A8R8G8B8 and X8R8G8B8. The tick count is now around 160, the same as in beta_22.

It’s interesting that the default value for the back buffer in beta_22 is X8R8G8B8 too and the renderer does not slow down, so there might haven been made a change in the rendering from beta_22 to beta_23.

We tried the same on different pcs, but only one had this problem. So if you use a ATI Mobility Radeon HD 2400 you might have the same problem.

Is it possible to change the default back buffer format for the ex9 renderer in vvvv?

hmmmm. i saw some issues that could be related to this when I first started using an i7 chip with vvvv. I started this post, https://discourse.vvvv.org/t/5727.

My solution to the problem revolved around changing the format of the backbuffer.

I never really really dug much further as I only use my i7 for non vvvv related stuff. Our quadcore’s no problems at all.

Are you using an i7 by any chance simon?
