GPU error viewing (light) composition on full quality.
I’ve made a composition of 2000×2000 with one solid with fractal noise and three glow effects applied. I’m using a i9 machine with 8Gb of VRAM. When I open this project on my Macbook (i7 with 512Mb of VRAM) and set the preview quality to “Full” I get an GPU error message:
“After Effects has encountered a failure related to GPU-enabled effects on this frame. This is likely because your GPU is out of memory, or because the frame size is beyond the capabilities of your card”
I’ve made far more complex projects on my Macbook so I decided to create the exact same composition again, but this time on the Macbook from scratch. Now everything works just fine! So I get the feeling that something goes wrong when opening a project from another computer. Any suggestions?

That sounds odd. It’s possible that some of the values are different on the layers. For example, Glow could really expand the size of a layer. Are they both 32-bit?

Both projects are in 8-bit and both machines are running the latest version of AE (17.1.4).
To indicate the problem I’ve uploaded the two projects here:

Both are identical, but one is made on my iMac and the other one on my Macbook. The Macbook gives the GPU error when opening the iMac project and previewing set to full quality.

They’re not exactly identical. The solids are different colors and the composition lengths are very different.
That said, those differences shouldn’t be causing the error you describe. I opened both projects on my Windows machine with NVIDIA’s GT730 GPUs in it and neither one had an issue.
I’d suggest filing a bug report.
(I’ve never seen someone layer glows in 8-bit before. Usually they behave much more beautifully in 32-bit, by the way.)

You’re right, they’re not exactly identical, but in terms of CPU/GPU heaviness they are. The projects are just for testing purposes. I’m trying to run RenderGarden on both my machines and my Macbook gives this GPU error every time. At first I thought it was due to the fairly complex project I’m working on, so I ended up with these simple test cases of which I’m sure my Macbook can handle.
Working in 32 bit would be nice, but when you’re working in 6000×6000 with a lot of layers then 8 bit is far more manageable both in render times as in prerender file sizes.

The fine people at MekaJiki RenderGarden pointed out that the project settings on my iMac had GPU Acceleration enabled where my Macbook creates every new project with Software Rendering enabled. So switching to software rendering did the trick. Hyper-threaded network rendering at last!
