Short description of error
When a movie clip is read into a background image and displayed on a 3D view, the FPS decreases in a sequence of 2K or more.Even in full HD, FPS decreases a little.
There is no problem if you play only with the movie clip editor.
Regardless of file format or file size, resolution seems to be involved.
There was no problem if the resolution was dropped to 2k or less.
Even if the sequence is full HD, the FPS will drop slightly. There is no problem if it is less than Full HD.
Below is a comparison with 2.79 under the same conditions.
Exact steps for others to reproduce the error
- Open file
- Play animation (and make sure it is not able to play at 1200FPS)
- In properties editor, toggle Show Background Image
FPS rate will drop significantly
