Why am I experiencing high CPU usage while viewing documents in PrizmDoc on Internet Explorer?

Question

When viewing documents using Internet Explorer 11, we are noticing an abnormally high CPU utilization. It gets worse when zooming in up to 800% through the PrizmDoc Viewer. It only seems to happen on certain machines. Why might this be happening?

Answer

A possible factor for this type of performance issue can potentially be corrected by enabling Internet Explorer’s hardware acceleration feature.

This feature can be enabled or disabled with the following steps:

  1. Open Internet Explorer 11, click on the Tools icon, and select Internet Options.
  2. Navigate to the Advanced tab and enable the Use software rendering instead of GPU rendering option.
  3. Click Apply and restart the browser.
