High CPU usage and performance issues #823

Open howdev opened 4 years ago

howdev commented 4 years ago

I used previous version 0.3 of the recorder and nvenc active and low quiet cpu usage at 4k recording. Now 0.4.2 CPU usage 30% and noisy, the recording is lagging and flickering even I checked the video encoder engine is active in nvidia-settings. The flickering is reduced when using 30fps instead of 60fps, but the CPU usage does not come down. I tried both the nvenc h264 and hevc. I am on Mint 19.3. I changed the cinnamon vsync, no difference. What do you think might be, nvenc driver, cinnamon or the recorder

Are you sure that the only thing you changed was updating SSR? Or did you also update other things (e.g. ffmpeg)?

howdev commented 4 years ago

Possible I had other things updated but minor version; Mint 19.x The 0.3 software encoding has less flickering than 0.4. In either version software encoding has less flickering than hardware encoding. I downgrade cinnamon to 4.2 still the same.

For the flickering problem, this is a known issue with all GNOME 3-based window managers (including Cinnamon), see: https://www.maartenbaert.be/simplescreenrecorder/troubleshooting/#the-recording-occasionally-flickers-showing-parts-of-the-desktop-background-instead-of-windows Does the problem go away if you try a different (non-GNOME-based) window manager, like Openbox, KWin (KDE) or Xfwm (XFCE)?

XFCE don't have the flickering. So I guess is Cinnamon. I couldn't try Cinammon 4.0, possibly after that version has the flickering. I remember 2019 I used this recorder and was fine.
