Steps to reproduce

  1. Open TG desktop
  2. open broadcast
  3. 95% CPU Usage Distro: Linux Mint 20.2 Uma base: Ubuntu 20.04 focal

Expected behaviour

8-12% CPU Usage.

In Windows 11 ~8% CPU Usage

Actual behaviour

80-98% CPU Usage starts to slow down. normally nothing can be done on the computer. bug TG

Operating system

Do you have NVIDIA?

Yes Nvidia

The proprietary NVIDIA driver is blacklisted, so all the rendering is software-based and high CPU usage is expected. You have to either switch to open source drivers, replace your hardware or switch to another OS.

Was he recently added to this list? because before, maybe before the new year everything was fine.

ilya-fedin commented 1 year ago

No, it was added in October 2021. Maybe you just wasn't watching broadcasts in such quality (even if you were watching this exact broadcast previously, they still can change the format or quality of the stream I guess).

Open drivers have problems on my machine, pc won't turn off in sleep mode and I need CUDA kernels. It turns out, poor support for Linux users. It's a pity, please make normal support for Linux

ilya-fedin commented 1 year ago

It's sadly not possible as the underlying toolkit (QtWidgets) has problems with NVIDIA. The only way to get good NVIDIA support is to rewrite the app to another toolkit: QtQuick, Flutter or Electron. Either way it means entire app rewrite and that's likely too much for a part of 1.82% of the userbase.

maybe you need to try a diferent linux distribution.

ilya-fedin commented 1 year ago

I don't think that would really help. Both open source (due to reverse engineering) and proprietary (due to NVIDIA's declining of Linux practices) drivers are of bad quality on Linux, unfortunately.
