That will depend on your render settings and what you actually use to produce your 3D content. E.g. an extruded text layer that is based on a complex font with lots of lines or a font that simulates a dot raster may produce so many micropolygons that it consumes all your VRAM. and naturalyl higher quality settings will push this further. Similarly, a single huge reflection layer could consume all memory. In the end, 1 GB of VRAM isn't really that much for these types of things...
The check that After Effects is making to see whether or not to show you that message is whether you have 512MB or more VRAM free. Web browsers, other applications, and additional monitors all use a lot of VRAM.
The reason that After Effects is doing this check is because if it didn't and you ran out of VRAM in the middle of a rendering operation, a crash could occur.
See this thread:
Well I don't use the raytrace engine because the response time with AE is as fast as the internet in 1994.
At least with the gtx 470/1280 vram card.
I don't get it, Maya, 3d Max, Scratch, all work 100% fine with my card.
AE obviously requires the "motherload of video cards" to run smooth.
Also, I read the other posts and I don't feel so bad. There are people out there that have better video cards & more ram than me (16gig) and they are having the same issues.
This is clearly a problem with ADOBE. They can't expect ALL of us to buy the top of line video cards and UNPLUG extra monitors.
What's that I hear?.....I think I hear an update soon with a fix.
"Then this message isn't relevant to you. You can carry on without any concern"
The reason why I don't use the "raytrace engine" is because it lags way too much for me.
I don't think anyone here would use it as a replacement to maya or max, however, it would be so nice to be able to zip around in 3D space and "bend" a card (soild) and project onto it without it lagging. (like Nuke)
I gotta agree here. If AE is gonna crash because of low memory then there is a problem with AE! They need to fix or prevent it from crashing by watching as it happens. We could get a 8GB card and it could still crash if that were the case and we were rendering something BIG. And, as others have said, all our other programs run just fine. I'm moving over to HitFilm for RayTrace now and use AE for the motion graphics side. But thats only because Adobe sees fit to force our hands. It's evident that they have no interest in supporting us mobile graphics professionals. I have my MacPro on order for my studio based stuff but when I go mobile and need things to just work I keep my options open. I've got the most fully loaded Mac laptop there is and even this keeps getting the stupid VRAM messages even with all other apps off and no other monitors. So there is something very wrong with its calculations.

The After Effects CC (12.2) update and After Effects CS6 (11.0.4) update include fixes and changes regarding the OptiX library for the ray-traced 3D renderer that make VRAM handling better, prevent crashes, and otherwise improve the experience in this area.
Let us know how it's working for you after you've installed the updates.
