Scrolling smoothy on adobe reader

There could be a few reasons why scrolling a PDF feels less smooth in Adobe Reader compared to a web browser like Mozilla Firefox:

• Hardware acceleration: Web browsers like Firefox tend to leverage hardware acceleration better, allowing smoother scrolling and rendering, especially on lower-end or older hardware. Adobe Reader may not take full advantage of GPU acceleration.

• Software optimization: Browsers are heavily optimized for smooth scrolling and rendering of web content, which is their primary function. Adobe Reader is optimized for   PDF rendering accuracy over scrolling smoothness.

• Single-threaded rendering: Adobe Reader may be rendering PDFs on a single CPU thread, while browsers can take advantage of multiple threads for rendering and compositing.

• PDF complexity: Very complex PDFs with many images, vectors, and fonts can be more taxing for the Adobe Reader rendering engine compared to simplistic HTML rendering in browsers.

• Settings and mode: Adobe Reader may have certain settings or viewing modes enabled by default that prioritize other aspects over smooth scrolling.

To improve PDF scrolling smoothness in Adobe Reader, you could try updating to the latest version, adjusting performance-related settings if available, or switching to a different PDF viewer that may be better optimized for your system. Some users have reported better scrolling by disabling protected mode or enhanced security options in Adobe Reader preferences.

Scrolling in Acrobat is smooth. Mozilla (?) has nothing to do with that.

What Acrobat and version are you using? What is your OS and version?
