Hi everyone, im starting to do a lot of work with after affects on my iMac. iMac (Retina 5K, 27-inch, 2017) Memory 32 GB 2400 MHz DDR4 and Radeon Pro 575 4096 MB Graphics Card. Im finding the render speeds really slow and previewing the clips really slow. Is there anything I can do to help speed things up? Ive been told it is worth looking at an external Graphics Card but im a bit out of my depth on the tech side of things. Id love any tips or advice that could help?
Thanks Matt

My professional opinion is that buy a decent pc for work.
Keep the iMac(Retina 5K, 27-inch, 2017, emory 32 GB 2400 MHz DDR4 and Radeon Pro 575 4096 MB Graphics Card) for the show. If somebody asks why you charge incredible amount of hours, just show the stuff on the mac and say:
See that's what I do on this industry standard equipment for your money!

How have you setup your scratch disk? Setting up that with a high speed SSD, keeping project files on separate high speed SSD = considerable performance boost.
And I think rendering to a normal HD works out better too, I seem to recall... I remember something being said about writing long/large files to a traditional HD is better than a SSD.
- Are SSDs ok to use as scratch disks these days? Probably, but how's the write cycle degradation? Mind you, I suppose a 128Gb SSD is pretty cheap nowadaysdetritus

did you take a look at memory management? like cleaning caches, making sure enough disk space allocated, split cache, virtual memory and output to different disks?

For rendering faster, get RenderGarden ($99) to take advantage of the other cores (AE only uses one core) >
https://www.mekajiki.com/renderg…For RAM previewing, your iMac is more than fine, it is what it is really, so you need to adjust HOW you're previewing. BTW, I'm on a new iMacPro and I still have a long preview wait if I just hit spacebar with nothing really adjusted. The things you can do are:
- Adjust quality (set to Auto, Half, etc). Sometimes you need to preview in Full, but sometimes lower quality will suffice.- Use proxies for your nested comps where you don't really plan on changing things or any clips that use complex effects that take a while to render.
- Make your preview duration area smaller on the timeline. Sometimes I just want to see that 1-second of animation and have it loop over and over so I can tweak animation. No need to preview 5 seconds if you only need to see the first second.
- Toggle Effects using the switches. If you don't really need to see the effect applied on something in the comp, temporarily turn it off so previews happen faster.
- Adjust Region of Interest area, perhaps you don't need it to render the entire comp area but only a small portion of it.
