If you play games regularly, particularly multiplayer games, then chances are you have Discord installed. Unfortunately, a recent update to the app has introduced a bug that unintentionally harms Nvidia GPU performance.
The bug seems to have an impact on memory clocks, reducing them by up to 200MHz on a number of RTX 30 GPUs, as reported by users on Reddit. Nvidia has already acknowledged the problem and a temporary solution is in place. For the temporary fix, you need to download the GeForce 3D Profile Manager and create a new setting for Discord, which will stop the GPU from downclocking its memory while Discord is active.
The update in question is the same update that introduced AV1 streaming with RTX 40 series graphics cards, although oddly enough, users are primarily noticing this bug on RTX 30 series GPUs, and not Nvidia's latest and greatest.
The bug will be fixed with another Discord patch ‘at a later date'. In the meantime, you can check out Nvidia's support article for the temporary fix.

KitGuru Says: With newer PC games being much more demanding on GPU memory, an issue like this may have more of an impact now compared to previous generations. Have you encountered this bug with Discord running while gaming?
