GPU slowdown wins Discord bizarre bug of the week • The Log
In case you’re obsessive about frames per second or CPU and GPU utilization, you’ll have observed some unusual habits when utilizing Discord with Nvidia graphics playing cards just lately.
When taking part in video games with Discord open within the background, the Nvidia GPU reminiscence clocks run slower than they need to be.
The bug, first noticed by of us on the LinusTechTips forumappears to be tied to how Discord connects to Nvidia’s encode/decode engines for video streaming.
How far the reminiscence clocks drop appears to rely upon which card you employ. Nvidia’s 30-series playing cards appear to lose round 200MHz whereas Discord is open, though some customers have reported drops of greater than 500MHz on older 10-series playing cards.
The Register was in a position to reproduce this problem on an RTX 3060-based gaming system utilizing MSI’s Combustor take a look at suite. As quickly as we began streaming with Discord, reminiscence clocks dropped from 7500MHz to 7300MHz.
Nvidia confirmed the difficulty in a assist bulletin printed earlier this week, noting that “after a current replace to the Discord app, customers could discover that graphics card reminiscence clocks won’t attain full speeds when launching a sport.”
The chipmaker additionally famous {that a} repair is within the works and “can be pushed to customers’ PCs through an over-the-air replace at a later date.” Nevertheless, it isn’t clear what change to Discord could have triggered the issue. Some discussion board members have speculated that it could be associated to the extent of AV1 codec assist on Nvidia 40 sequence playing cards. This might make sense as the issue solely seems when utilizing Discord’s voice and streaming function.
Within the meantime, Nvidia has supplied an answer for many who cannot or do not wish to wait. The answer includes downloading Nvidia’s GeForce 3D Profile Supervisor utility and modifying the SLI profile utilized by Discord. You will discover a full breakdown here.
So do you have to apply Nvidia’s answer or look ahead to a driver patch? Properly, from what we are able to inform, you may most likely wait, since you’d be hard-pressed to inform the distinction, particularly on newer playing cards.
Even on a mid-range card just like the 3060, a 200MHz drop, nonetheless anomalous, is not that a lot. And in our testing, we discovered no noticeable drop in body charges in Doom Everlasting operating at 1080p “Nightmare” settings with dynamic decision disabled. Body charges hovered between 177 and 220, no matter whether or not Discord was on or not.
However should you’re utilizing an older card, the efficiency hit is perhaps extra noticeable. In that case, it could be essential to use Nvidia’s hotfix till an acceptable replace may be launched. ®
