Rendering zoomed-in vector layers is very slow
Posted: Sat Mar 24, 2018 3:52 am
I have a fairly simple scene with some vector layers. Each layer has several vector shapes with maybe a few dozen points per shape, so nothing very complex. They use basic colour fills and strokes with no textures or effects.
The project is set to 1920x1080 pixels. If I render the scene at it's normal size it renders at about 10fps. However, if I zoom the camera in (either using the zoom tool or the Track camera) by a factor of about 10 so just one of the shapes is now visible in the screen and fills most of the screen, then each frame now takes about 5 seconds to render! This is 20 times slower!
I assume that this may be because it is actually still rendering the *entire* scene - ie. rasterising the vector objects at what is now 10 times the resolution, even the parts which won't be visible in the 1920x1080 output frame, and then just cropping to the part which is visible in the frame.
If that is indeed the cause for this dramatic slow-down in rendering speed, is there any way to fix it? If not, any idea what's going on?
I have been looking for options but can't find anything which seems to be related to this problem.
