Hello,

Thank you for contacting PDFTron Support.

Using client-side rendering of WebViewer is slow in IE, it is a known issue and there is nothing we can do about it. IE has a number of issues, e.g. IE has limited memory, IE’s JavaScript engine is slow, etc. For more information you can read here https://www.pdftron.com/documentation/web/guides/browser-support/
If you want to support an old browser like IE, we recommend WebViewer with a server option. With server options, most of the rendering happens on the server and not in IE. https://www.pdftron.com/documentation/web/guides/wv-server-deployment/
