- Fixed Code review comments
Generally looks fine, only minor things noted.

This seems to be fixed now in (the upcoming 2.91) since (4212b6528afb0) - image draw refactor. Closing it now, let me know if the issue is still around.

This seems to be a problem in addon then, I'll edit the description to indicate this.
I didn't know it was an addon actually...
It only happens when the addon is activated (https://docs.blender.org/manual/en/dev/addons/object/edit_linked_library.html)
- In the Sidebar: Collapse and Expand the "Edit Linked Library" to see the difference in frame rate

Problem was with Viewport Anti-Aliasing. With it turned off performance is back to rock solid 60, with no perceivable difference in appearance.
Seems an unnecessary option to have enabled by default on Retina machines.

@Sam Van Hulle (sam_vh), This seems to be better in latest master, IMO good enough to close this issue.

@Demeter Dzadik (Mets), the idea you are suggesting is not impossible to be implemented, but it requires some deep changes in how the system is currently functions. It might also cause worse performance in "real" cases, because it will be more difficult to keep all CPU threads busy bu requiring to wait while tree of animation/drives is evaluated.

Thansk for the report,
Can you try the latest daily build too?

Compiling FFmpeg with NVIDIA hardware accelerated settings: https://docs.nvidia.com/video-technologies/video-codec-sdk/ffmpeg-with-nvidia-gpu/index.html

There is a new ffmpeg gui which includes options for all the new HDR 10 bit formats and Nvidia based hardware encoding here:
It may be useful to generate test files to detect what codecs currently aren't supported by by the Blender built-in ffmpeg and also compare render times with and without hardware acceleration, in order the check the necessary build flags are being set.
All the new hardware settings in ffmpeg explained: https://developer.nvidia.com/blog/nvidia-ffmpeg-transcoding-guide/#disqus_thread

Currently, the VSE ffmpeg lib can't decode AV1. Ex: https://www.youtube.com/watch?v=PVGeM40dABA
Ffmpeg 4.2 includes a AV1 decoder: https://hub.packtpub.com/ffmpeg-4-2-releases-with-av1-decoding-support-through-libdav1d-decoding-of-hevc-444-content-and-more/
And an AV1 encoder: https://trac.ffmpeg.org/wiki/Encode/AV1
Less than 45 FPS now on 2.83.5.

@Dalai Felinto (dfelinto) Got it! I thought this was exact the same issue, so I didn`t new report. But if U suggest so, I'll try.
Hi @Vyacheslav (hitrpr) - this is already marked as known issue, so although more information can help, the report already has all the information a developer would need to look at it. In your case you can just report your issue as a new bug, and the triaging team can handle the investigation and eventually merge the tasks if it comes to that. Just please refer to this task when opening a new one.

Here is another example. Even if you apply Subsurf, switched Mirror will be calculated on every move. You can test it with this file (if lags are not so noticable — increase subdiv)

D8234: Use DrawManager for Image/UV Editor is more complete, so time to abandon this patch
