    Very Slow Rendering on Gaming PC

    michael29angelo Level 1

      Rendering in Adobe After Effects CC 2017 on my gaming laptop is too slow! I have performed a test with two laptops and a desktop PC.


      Let's name my gaming laptop as PC1. This computer is where the slow rendering happens. It took 4 hours to render my video. Here are the specifications of my laptop:


      CPU: Intel Core i5-7300HQ

      OS: Windows 10 Home (64-bit)

      RAM: 4GB

      GPU: NVIDIA GeForce GTX 1050 (2GB GDDR5)


      The next laptop will be named as PC2. This took only 40 minutes on rendering the same video. The specifications are:


      CPU: Intel Core i7-5500U

      OS: Windows 10 Pro (64-bit)

      RAM: 8GB

      GPU: NVIDIA GeForce 820M (4GB)


      The desktop PC will be named as PC3 and it took almost 50 minutes to render the same video. The specifications are:


      CPU: Intel Core i3-3210

      OS: Windows 10 Pro (64-bit)

      RAM: 8GB

      GPU: NVIDIA GeForce GT 630 (4GB)


      How can I achieve fast rendering on PC1? Two of the major reasons in buying this laptop are video and photo editing. Can AE use my GPU on rendering? Please help me how to adjust or upgrade something. Thanks!

          Start by turning of GPU functions in the relevant settings. everything else will have to be figured out by tweaking the graphics driver and its settings.

            Not sure what "turning off GPU functions" will do for your rendering speeds. If anything you want the GPU to do as much as possible right? But After Effects only uses GPU for a few things so it shouldn't make a huge difference in rendering speed. The biggest factors in rendering speed are single core performance of your CPU and amount of RAM. 4GB is really very low although I would hesitate to point to it as causing a difference of 4 hours vs 40 minutes rendering time. It might though.
            The Core i5 is actually faster than the i7 (since it's a newer generation) so it's not your CPU.
            If there's an option to add more RAM to that laptop I would do that anyway. You can really almost never have enough RAM for After Effects, but it will also generally speed up your computer.
            Of course some general tips would be to check if any other programs are running in the background, and all your drivers are up to date. Also check that your laptop isn't in any power saving mode, where it's throttling down the CPU. Set the power plan in Windows to "high performance" (I'm assuming you are not running on battery when rendering).

              You try a tool called RenderGarden. It is a paid tool. It is a 7-day free trial. It is worth using it.

                That's a nice plug for RenderGarden but it's really not a very helpful answer to the OP's question is it? He's asking why he has vastly different render speeds for different computers and how he can achieve better speed on a specific configuration and you give a link to a plugin for distributed network rendering.

                But ok let's from now on, for everyone who asks anything about AE rendering speed just link to RenderGarden and be done with it then.
