After effect supports Radeon Crossfire X or Nvidia SLI?

[sungjinw66398623]

I have configured my pc's single VGA card to two VGA card as crossfire X to reduce rendering time

So I confirmed that crossfire X' function works normally and it could reduced rendering time in premiere CC 2019

but I try to render using after effect, i confirmed that only one of the two vga cards works.

Can anyone tell me? crossfire X function is only supported in the premiere CC 2019, not after effect CC 2019?

My PC environment is as follows.

OS : Window 10 Pro 64bit

CPU : Ryzen 2700X

VGA : MSI Radeon RX 580 Armor OC D5 8GB x2

Applications : Premiere CC 2019, After Effect CC 2019, Media Encoder CC 2019

Graphic Card Driver : Adrenalin 2019 Edition 19.2.3

Mainboard : MSI B350m Mortar and Graphic card each installed PCIe3.0 x16 , PCIe2 x 4 slots

Thanks

AE only uses one GPU. You shouldn't need Crossfile for Premiere, it should recognize both GPUs without a Crossfire bridge. Also, while there are a growing number of GPU-accelerated effects in After Effects, Premiere has a much more robust GPU-acceleration pipeline. It takes a long time (relatively speaking, for computers) to pass frames back and forth between the CPU and GPU, so make sure your effect stack is as efficient as possible. If you use several GPU-accelerated effects in Premiere and then have a single CPU effect in the middle of that stack, AE will have to pass the frame to the CPU to render that single effect, then back to the GPU to continue rendering the other effects.
