Nvidia is on the verge of releasing a repair for its ongoing driver DPC latency points. In a Twitter put up, Nvidia’s software program high quality assurance spokesperson Manuel Guzman stated a repair is prepared. Nonetheless, the replace launch nonetheless needed to undergo the usual QA testing process earlier than distribution.
Whereas Nvidia has gone to nice lengths to reduce enter latency and enhance responsiveness with tasks like Nvidia Reflex, customers of its drivers have been affected by DPC latency points for a number of GPU generations.
In case you are blissfully unaware of DPC latency, it’s system latency launched by a Deferred Process Name (DPC) in Home windows. DPCs have been designed for high-priority duties to defer required however lower-priority duties for later execution. Nonetheless, DPC buffers can get crammed, leading to stutters, skips, and comparable glitches in video and audio. These jarring latency signs are extremely undesirable in gaming, viewing movies, and creating or listening to music.
Individuals who suspect they’ve DPC latency points can obtain varied instruments to verify and assist reduce the problems. Nonetheless, for a correct repair, you will have a tool driver that has been coded to reduce extreme latencies in DPCs. If in case you have a laptop computer or pre-built PC, NotebookCheck maintains a listing of methods and their examined DPC latencies – decrease numbers are higher.
In line with Mr. Guzman, Nvidia has now reached a stage the place it has mounted its driver DPC latency points. After all, the proof of the pudding is within the consuming, and we will see shortly when the mounted driver(s) arrive. Because the Nvidia software program QA spokesperson says, please “keep tuned.”
GPU Monitoring Apps and Updating Nvidia Drivers
From Guzman’s Twitter thread, the place the DPC latency information emanated, there comes a strong advice to exit all of your GPU monitoring apps earlier than updating Nvidia drivers. The crux of this potential challenge is that in the event you overlook or neglect to comply with this recommendation, “the GPU monitor utility could inadvertently set a decrease energy goal leading to decrease efficiency.”
Nvidia Players Utilizing Home windows 11
Mr. Guzman additionally recommends that Home windows 11 customers with Nvidia GPUs replace to the most recent model. Apparently, Microsoft’s newest replace addresses Timeout Detection and Restoration (TDR) errors which may in any other case interrupt gaming periods.
