Force After Effects to use certain GPU

[jensl95989480]

On use two Nvidia Cards NVIDIA GeForce GT 750M 2 GB and a NVIDIA GeForce GTX 1080 Ti with 11GB VRAM on my MacBook Pro (Retina, 15-inch, Mid 2014).  They have different CUDA compute level and different VRAM.

How I can force After Effects to use only my powerful GTX 1080 Ti?

Thanks for any advice!

After Effects doesn't use the GPU for much so you may be overestimating the advantage a better GPU will bring. That being said, more and more native effects are being GPU-accelerated. AE version 14.2 now accelerates Fractal Noise and it makes me very happy.

And, of course, a number of third party effects like Element, Red Giant Unverse, etc. run exclusively on the GPU.

AE will use the GPU that is powering your display.

The solution is simple.  Carefully remove the 750m and gently place it in the trash.   Or save for a scrap build.

Unfortunately, I can not remove it. It is firmly installed in my laptop. But maybe I can power my screen with the bigger card. Let's see ...

Hi Kevin,

This is currently a concern for me; I'm on a Dell laptop with an integrated Intel Iris Pro graphics chipset in addition to an NVidia Quadro M2000M chipset. Is there any way to set After Effects to use only one or the other without disabling the lesser-desired chipset at the BIOS level? (That's my current solution and it's less than ideal.) Thanks in advance!

Hi Chris,

Here's an article that may help. How to Force Graphics Options in PC Games with NVIDIA, AMD, or Intel Graphics

Let us know if that helps.

AE crashed, stuck with a GPU memory error splash screen.
When clicking the 'GPU information' button in Settings, it shows some random info, but the useful part says 24gb of VRAM, and that is my secondary GPU. I have no display attached to it. My displays are connected to my 16gb card.

So, AE is not using the primary (display out) card, but switches to whatever has more VRAM?

I'm on a desktop PC with Windows and 2 AMD cards. Primary is 6800 (display out) and secondary is 7900.
Looks like the error I had was probably caused by the secondary card's VRAM being full due to Davinci Resolve running on it. And AE also wanted to use it for some odd reason. I specifically directed Resolve to the bigger card for editing and I want to do animations for the video projects at the same time on the smaller card.
