Cineversity

I have a query. I have quite a good machine, but while playing back a simulation as simple as this, I dont know why Cinema4D does not utilise the full power. I do not get a fast playback. it is quite choppy. Please can someone tell me if I am missing anything? Attached below are the usages of CPU, RAM & GPU while playback of simulation.

Hi nikhil_shahapurkar,

I could guess how the scene was created (looks like one of the recent tutorials), but I think that guessing/assuming is a waste of time on both sides.
Typically you need to share the scene-file, so we can talk about facts.
If you need an upload link, please let me know. (Amazon, Dropbox, Apple, Adobe and Google are the only one I use)

Generally speaking: Some calculations do not have a multithread option. I don’t know if the problem is in a high setting of your Cloth Object, but that is guessing.

Technical problems, if it is one, will be re-directed to the Support.

All the best

Hello! Thanks for the response.

I am basically wondering, since I have used the same settings as shown by the instructor in the recent tutorials, how come his playback is faster than mine. So I am trying to explore what the playback actually uses - CPU, RAM or GPU. Does it matter if I have only 1 GPU or would 2 GPUs help?

Even in X-Particles if I give trails to the default settings over a few frames the fps drops and becomes choppy.

I am basically learning Cinema 4D since last 8 months. So very new to it and am trying to understand how everything works. My file size is around 10MB. So can you share any details as to how I can share it with you. Also, since the cloth tag has been cached, I will basically need to send you the cache file also. Please can you tell me where it gets saved?

Hoping to solve this issue soon.

Thanks and regards,
Nikhil

Hi Nikhil,

I have sent you an upload link. I will have a look into your file in the morning (I’m in L.A., CA), I will get an automated email when a new file arrives, no additional message needed.

If you like to compare it, I would like to encourage you to use the files provided. I do not know the specs of his machine, but I assume he has a very nice set up.

Yes, I hope I can find something.

My best wishes.

P.S.: you should test the latest Cinebench and google results, to get an idea how your set up is doing in comparison.

Hello. I tested the latest Cinebench on my computer. it scores 6357

Hi Nikhil,

Your scene is not equal to the scene in the tutorials. I have compared the provided files from your side and the one EJ.

The most obvious one is the number of clones, if that is set to the same number, your scene is not at all slower.

I have made a screen capture, and the two run relatively equal if set up to the same amount.

The only measurement that I can provide is the fps of the screen redraw, while I was recording the screen capture on a 5K monitor, which slows things down, while other processes might randomly run on the system.

I know EJ back from the Pixelcoprs (15 years ago), even at that time he was already a broadcast professional, well connected in his field, and you can certainly assume that his gear is as fast as he likes to have it.

You might check the Level of Detail settings, if things go really slow, or set the Subdivision to zero for the setup time. A common mistake that many people do is a) set the subdivision and the number of clones to high, while in set up mode, and b) place all kind of stuff in the scene that is not needed at that point, or leave things in the scene, that could be deleted. Keep it simple as long as possible, save often and place items not needed on Layers while shutting all the options (generate, animation, etc.) off from that layer.

All the best
