Hello!
I did a little benchmarking today (patch attached) and there are some strange behaviours.
-
In a patch without renderer, just with a mainloop and a Timing node, vvvv seems to run always with a little more then half the fps entered in the mainloop. So with 120 fps, I’m getting max 64 fps. And it doesn’t seem to get any higher than that. With a 240fps Mainloop, I’m only getting 66fps tops.
-
When adding a renderer (just the renderer, nothing to draw is attached) my framerate drops to 40 fps, even if the mainloop is at 120 fps.
-
When I add a perf meter, the framerate jumps to 56-59 fps.
-
In the renderer I have to switch to Presentation Interval ‘immediatly’ to get more than 60 fps.
The computer I’m working on is a Athlon 64 4200+ with 2GB RAM and a NVidia 7600GTX so there should be enough performance…
