Windows 10: What are the changes between Windows 7 and 10? When converting videos frames are dropped in...

We have used Windows 7 and Pinnacle Studio 21 to convert video tapes to MP4's and on a regular basis 5 frames of the video are dropped at the start and no others are dropped after. The only time frames do drop after the 5 is if you run other programs on your computer at the same time. The Pinnacle program gets interrupted while it plays and copies frames, so frames start to get dropped/skipped. This means when you watch the conversion afterwards, the video skips while it plays and doesn't play like the original.For that reason, once a video conversion starts, the computer is left alone until i

Dropped frames in Firefox after upgrading from Win7 to Win10

Someone? Maybe move this to Performance & Maintenance or to General Support.
Tried Opera Portable, YouTube videos drops frames both in Windows 7 and Windows 10. (~0.5% at 1080p60, ~5% at 1440p60)

In Summary:
Firefox drops frames (at 1440p60 2160p24/25/30) in Windows 10, but not in Windows 7 (only rarely frame drops at 2160p30).
I think 1080p60 and 1440p30 doesn't drop frames in Firefox on Windows 10.
I can play 2160p30 YouTube in Firefox for Android on Galaxy S6 Edge+ without frame lost... but 2160p24 in Windows 10 drops frames...
VLC doesn't drop frames for these videos (1440p60, 2160p24/25/30), both in Windows 10 and 7.

Another issue I have is with DOSBox under the following settings:
Code:

Video and audio stuttering in fullscreen in Windows 10, but it works smoothly in Windows 7.
However it works smoothly in Windows 7 and 10 in non-fullscreen mode, even if I change the resolution to 1728x1080. I have 1080p 60Hz monitor.

Thanks

 

Edge Chromium dropping frames on YouTube videos

Hello (system specs are on the profile).

I've both Edge Chromium dev (Version 83.0.478.10 (Official build) dev (64-bit)) and Edge Chromium (Version 81.0.416.58 (Official build) (64-bit)) installed, the browsers are fast overall but the problem is, every time I watch a video on YouTube, there are lots of dropped frames. The thing is, with Firefox I've almost no dropped frames, and with Edge, I've like 300 times as many dropped frames.
For example, in this , I've one dropped frame in Firefox (and it's in the beginning, so it's irrelevant):



While I've 393 dropped frames in Edge Chromium (both versions):




I've hardware acceleration turned on, if I turn it off, the videos become unwatchable (lots of dropped frames, as CPU can't keep up).

Do you know if there is something that can be done in order to fix it, or is Edge Chromium just slower?

Best regards.
