Hey everyone! In this quick video I will explain you, how you can speed up your render by assign Adobe After Effects to a specific Nvidia GPU on an multi-GPU system. This method works with other applications as well. Firstly, you should create a copy of “exe“ file. Go to Adobe After Effects Support Files folder, select AfterFX, press ctrl c ctrl v and rename it to something normal, like “AfterFX_gpu2“. Then drag-n-drop both exe files to a taskbar or create shortcuts on a desktop. Right click, right click, select Properties. At the end of Target add “ -m“ and rename it. Add “ -m“ in original shortcut too. Then go to Nvidia Control Panel, disable SLI mode. Then Go to Manage 3D Settings, Program Settings, and add After Effects exe file. After that assign Cuda and OpenGL to specific GPU. Then add a copy of exe, that we created earlier, and assign it to other GPU. Hit Apply. Perfect! Now you can launch two copies of Adobe After Effects, each of them will use its own GPU with separate graphics card memory pool. This might be very useful, when you have a lot of CPU cores, RAM and several Nvidia Cards, and you would like to use your render PC power as much as it possible. Otherwise both copies of After Effects would use only first graphics card and could easily run of GPU memory when working on intense complex projects. To minimize render time, change Output Module to image Sequence, I prefer OpenEXR DWAA format, it's tiny, fast and almost lossless, much better than PNG or TIFF on 4k resolutions. Then you should change Render Settings to Multi-Machine and check that Skip existing files option is enabled. Revise Output path and Save your project. Hit render and look, only second GPU works now. Ok! launch second copy of After Effects, open saved project and Press render. In case you are working with time-depending effects like reel smart motion blur, temporal denoisers, echo and others it would be better to split render region. Also some effects have its own GPU selection menu, like Neat Video Denoiser, check effect settings before rendering. That's it! Thank's for watching!
