Quality difference between source and timeline render I'm testing some high quality footage from Arri (https://www.arri.com/EN/camera/alexa/learn/alexa_sample_footage/) and I've noticed that PP when rendering the timeline lowers the quality considerably. 

If you reference the below image, I have only added a title only and the timeline render quality in PP is awful. 

Both my playback and pause resolution is full. 

If I remove the title from the timeline the full quality is restored. This issue will occur with any PP effect. If I don't render the timeline, the program sequence runs at full quality. 

The final render out is fine, but I want to work with the footage in high quality as my machine is more than capable. What am I missing here?

CPU: i7 4770K @ 4.3

MEM: 32GB

GPU: GTX970

SSD Disks
after posting this I randomly stumbled upon a setting in Preferences. 

Preferences -> Memory

Optimize rendering for performance
Changed to "Memory"

Looks fine now.
