NVidia GPUs slow down due to Discord?

Hi all,

There a report out today that a NVIdia GPU might slow down when you are accessing Discord's online website.
When playing games with Discord open in the background, Nvidia GPU memory clocks are running slower than they ought to be.

The bug, first spotted by folks over on the LinusTechTips forum, appears to be linked to how Discord ties into Nvidia's encode/decode engines for video streaming.

How far memory clocks drop seems to depend on which card you're using. Nvidia's 30-series cards appear to lose about 200MHz while Discord is open, though some users have reported drops of more than 500MHz on older 10-series cards.

Older GPUs seem to be more fallable, with newer 30 Series less affected.

Mind you: How many of our members play games with Discord running in the background? Whether this affects BOINC crunching via GPU's, I do not know !!

Tim
