Combustion Settings to Speed up workspace??

#1

The aprticles in my combustion are lagging a little. I have an ATI all in wonder 9700 in an fx-51 64 bit chip computer with 1 gig of Ram and 2 Raided 10,000 RPM hard drives… why am I getting lag…
Are there settings somewhere I can tweak to speed things up?

When I open up the task manager it says that Combustion is only using about 50 Megs of memory how do i tell it to you a lot more??

Thanks.

particle previews are OpenGL-- completely the fuction of your videocard until they are rendered as video. Have you installed the proper drivers for your video card ?

sounds like you have a rocking system otherwise.

Thanks I just got a 21 Inch LCD Widescreen for it too :slight_smile:

I’ll try to play around with the OpenGL setting on my card - but I really think there’s gotta be a memory apature setting somewhere in here.

Go to the preferences: “caching” and set it to 87%
more than 87% is not recomended because windows needs a lot of memory

In the past Combustion sometimes felt back to 50MB, I always look at the cache meter on lower right.

hope that was causing your problem

Thanks. That Helped.

When possible work in 2d not 3d. This will speed things up considerably.

here is another one:
only use a composite operator if you really need it.
In combustion 4 there is also the merge operator to do quick composites of two operators.
e.g. for titles fx it is enough to create a text layer and add the other operators on top of it without a composite.
Then add your preferred render output in the schematic view.

  • make full use of the Switcher operator. (commit to disk). can save serious headaches sometimes (and cause them at other times too hehe).

  • proxies are a way of life :slight_smile:

I have an ATI card too. I found that when I started combustion 4 that it was very slow - especially the particles - so I searched around in the preferences and found a setting under openGL general settings called “use software openGL” it was toggled on by default - so I turned it off and now my combustion is running about 20 times faster! don’t know why this was the default setting. Give it a try- it might be the same problem on your machine.

If you haven’t already done this: Right click in the viewport and choose “Use Open GL” (this option is in the Window menu as well). Open GL only supports simpler blend modes, and sometimes behaves strangely, so sometimes you might have to disable it.

You may also want to experiment with Open gl rendering, you find it under “settings” in the composite operator.

You should definately disable “use software Open Gl” in the preferences, unless you encounter problems.

Good luck!
