    Hi guys, bit of a rookie to the whole EGPU scene. Currently I have:

    - MacBook Pro 2015 13inch (3.1GHz Core i7 16GB RAM)
    - Razer X Core
    - Apple TB3 to TB2 Adapter
    - TB2 Cable (Cable Matters)
    - 23inch AOC External Monitor

    I am wonder about what graphics card to get to run X-Plane11 with high graphic settings?
    I have purgewrangler set up and ready to use with an AMD graphics card, but am also open to the idea of an Nvidia graphics card.

    Any advice appreciated. I did not buy a Windows PC as I need a Mac for various other things and wanted an all-in-one laptop.

    Unless it has already changed, XPlane 11 doesn't support GPU's, it is CPU-bound.

    MY GPU sits around 5% utilization with X-Plane 11 and my CPU runs at 99%.

    It supposed to go to Vulkan in a future release, when that happens, the flood-gates open (like it did in No Man's Sky).

    I would get at least a Nvidia 1070, or RX 580 and 8 Gigs VRAM...

    Thanks for you answer. When you say X-Plane11 does not support GPU's, does that mean the whole EGPU is completely pointless and it has no benefits to running it with X-Plane11?

    It's gaining metal support shortly. I'd go with the best AMD card you can afford and you'll be happy.

    With Metal support will this mean the eGPU will now be supported?

    X-plane definitely does depend heavily on GPUs, but also depends heavily on the CPU as well.

    When is it likely Metal will be up and running with X-Plane11?

    Probably later this year. It should still work okay as it is currently, but it will get a LOT better once Metal support is in place.

    Wow, I didn't know it was that bad. They really need to fix this.

    Hmm...
    I have been using X-Plane 10 and 11 for many, many years and I concur with the fact that X-Plane 11 is MORE CPU dependant than GPU dependant, but... having a bad GPU will affect performance hugely.

    ATM, X-Plane 11 is OpenGL based. Therefore the single-threaded CPU performance of OpenGL in combination with the GPU is the key for good FPS.
    While fluying around, X-Plane 11 uses max 2 Cores, lots of RAM and lots of VRAM (especially with Ortho-scenery loaded).

    IMHO, go with the best CPU, with a decent GPU but with lots of VRAM.

    On my iMac (27" 2017, i7 4.2 GHz, 32 GB RAM, Radeon 580 Pro 8 GB VRAM) I notice the GPU is starting to be the slowing factor. 8 GB VRAM is not a luxury.

    I hope the transition to Vulkan (PC) and Metal (Mac) will help us Mac-users. We don't have a 2080 Ti to play around with...
    Maybe the 16 GB Radeon VII in a future (i)Mac Pro will help us out.
