Step 2: Install the attached Windows registry settings

Attached to this article is a file titled PCMiler_registry_settings.reg. It includes settings that prevent PC*Miler from using hardware acceleration, which can lead to faster processing times and smoother performance on older machines. 

  1. Download and install the registry file on your computer. 
  2. You should see the follow settings under Avalon.Graphics added to your Windows Registry Editor.
