In after effects cc, when I scrub through un-renedered portions of the timline, the image in the viewer becomes too pixelated to make out until I release the mouse again. I get the same result with even a plain video file without any effects on it. It also does it if I go to adjust an effect by scrubbing a value with the mouse. Basically this is making it so I can't preview effects or other changes to my comp in realtime. I have to pic a value, let it render, see if it's good, change the value, let it render, etc... This also accurs regardless of the resolution selected (full,half,third,quarter).
...happenening only now, after I completely upgraded my computer & software.
Is this a settings issue?
Thanks!
