Low frames in Calibre

dysprove · 11-19-2020, 01:22 AM

Hello,

I'm not entirely sure what happened but I opened Calibre today just to find that it is running at 1-15 fps (lol). I updated to the most recent version, but the problem still persists. Does anyone know a fix that could possibly help?

Thanks.

fps in what?? on what OS? how are you measuring fps?

I am running windows 10. I am referring to literally the fps in the Calibre application when I have an epub file open. I have an overlay, Geforce experience, that automatically puts fps counters on all of my applications and the readings I was getting from the application ranged from 1-15 fps. Basically the entire program was very choppy. I know its not a hardware issue since I regularly run recent games on 144 fps+.

Thanks

Then its a driver issue, see https://doc.qt.io/qt-5/qtwebengine-debugging.html
