**System Information**
Operating system: Windows 10
Graphics card: 3071MB NVIDIA GeForce GTX 1060 3GB (HP)
**Blender Version**
Broken: ~~(example: 2.80, edbf15d3c044, master, 2018-11-28, as found on the splash screen)~~ 2.81, unable to find Hash from Splash Screen, 2.81.16
Worked: (~~optional~~ necessary for comparison) 2.80, unable to find Hash from Splash Screen, 2.80.75
Note: Can no longer find hash numbers on Splash Screens for 2.80 onward. Any details pertaining to the location of the hash number is accepted and appreciated.
**Short description of error**
Up to date, Blender's 2.80 builds, up to 2.80.75, from what I have checked, use no more than 1.10GB of CPU when working with videos in the Video Sequence Editor. However, some builds, specifically builds *before* 2.81.16, use upwards of 4GB of CPU. However, this changes with 2.81816, where it climbs up to 1.31GB, up to date. I had not checked any further, as I feared that if I had tried, it would have climbed up to 4GB, as I was accustomed to seeing happening.
**Exact steps for others to reproduce the error**
1: Open either 2.80 or 2.81
2: Start a new file: Video Editing.
3: Add in a video, preferably something longer than 5 minutes.
4 (optional): Waveform displaying on. (This does not matter.)
5: Proceed to scrub through the video footage, either forward or back.
6: Keep an eye on the bottom-right-hand corner, watching the consumption of CPU rise.
7: 2.80: Expect it to stop at around the 1.1GB range. 2.81: Expect it to climb into the 4GB range, if not mistaken.
Cannot attach .blend file, too large, even after packing everything.
