After Effects - How To Increase RAM Preview & Rendering Speeds
Original source date
Answer
Open up After Effects. Here, navigate to Edit, Preferences > Memory. On the settings window, you can see how much RAM you currently have on your PC, and how much After Effects has been reserved to use. To allocate more memory to After Effects, reduce this value to at least 3 GB. This will also depend on how much RAM you have installed. If you have less than 8 GB of RAM, set this value to around 3 GB. Navigate to the Media & Disk Cache tab. Make sure to empty your disk cache from time to time. This will increase your performance and frees up storage on your hard drive.

Close Memory-Intensive Processes & Apps
Prevent other programs from running in the background which you don’t need while using After Effects. Especially resource-intensive programs such as other Adobe applications will use up your available memory and prevent you from properly using the software.
