    Just wanted to know how I can do this. System profiler says my iMac is version 16.2
    I wanted to do this so I could play games on my Windows 10 dual boot I created with Bootcamp.

    It's an integrated GPU so increasing the RAM will increase the VRAM. This will only apply to a certain point, depending on how much RAM you currently have and what operating system you have, as it may already be maxed.


    1) You cannot upgrade the RAM on your model of Mac.
    2) Even if you could, increasing the VRAM for your GPU will have an infinitesimal impact on games performance. If it doesn't run smoothly now, it won't after increasing VRAM. Certainly nothing noticeable in real-world performance.
    3) Upgrading the HDD to an SSD would have a noticeable performance benefit for gaming in loading times, but for graphical intensive games, the GPU will still be the bottleneck.
    4) If you need to play some seriously intensive graphical games, the only option beyond a console/gaming PC would be an external GPU.

    Yes, and you aren't dealing with the most powerful of GPUs, so your limitations aren't because of the amount of VRAM, but the limits of the GPU itself. You won't be able to play games at high detail or resolution, and most modern games probably won't be playable at all (FPS too low).
