I wish I could provide some ideas but sadly my programming knowledge is limited! Monitoring cpu usage on my pc, it looks like the encoding process for the gif only uses one core – is it possible to employ more cores to speed up encoding, or leverage a gpu?

Thank you. Oh no you have good understand and this is a really good question. The reload is done not on a target web page in hidden chrome browser, but rather it’s a reload of whole gif/png on the client side. I don’t think it’s possible to reload less than a whole image. I was thinking perhaps the image could be chopped up to smaller sections, however browsers predating CSS will have problem placing images exactly adjunct to each other. I’m currently working on speeding up GIF image generation, so that may help. I’m also open to any ideas you may have.

You can upload to something like Imgur and I’ll inline it.
