Thank you for the report! Could you please attach your test case, and elaborate on why you expected the external GPU to be used? Generally, WebKit doesn't use discrete internal GPU either, preferring the integrated one.

I am testing webkit's recent changes that purport to support running animations on the GPU rather than the cpu. There continues to be dramatic difference between what Chrome can deliver compared to safari In order for me to show webkit in the best possible light I am hoping to flag the lack of support external gpu's to your team. I have attached an SVG file for a test case that highlights the difference in performance between chrome (which supports external GPU) and safari. This is an Operating system feature that apple has supported for 3+ years. https://support.apple.com/en-us/HT208544 The difference in performance between chrome and safari is dramatic. I can upload and link to a video showing this difference in performance if that helps to clear things up...

This is appreciated! Thank you - it was unclear whether this was about WebGL, having the test case clarifies it.

This is about WebKit not having GPU acceleration for SVG filters, when Chrome does.
