Description and steps to reproduce [Required]

During general desktop usage, in situations of CPU/storage spikes (e.g.: launching an application, opening a video file, running an installer etc.) with an A750 card, there are huge DPC latency spikes that result in mouse freezes for 1-2 seconds and audio stuttering/crackling. I often have Discord, Edge, an Hyper-V virtual machine, and Plex Media Server running most of the time. If I replace the Intel card with an NVIDIA one, the problem goes away. (Obs.: I fully uninstall the NVIDIA drivers using DDU when using the Arc card.) I use LatencyMon to monitor DPC latency.

Hello @dcominottim,

Did you start seeing this lag in the driver v4255? Did you try with the 4311?

I will replicate this on our lab, keep you posted!

Hi, @Arturo-Intel -- thanks for the message!

I have edited the OP -- I am actually on driver v4255, the latest stable offered to me.

I don't know if the issue manifested in previous versions because I wasn't using the A750 again until about a week ago.

I will try driver v4311 and let you know the results.

Hi. I've been experiencing similar audio stutter/crackling, although not this drastic - no mouse issues or freezes. I'm on a 13700k+B760, Win 11, board audio jack. Should I open a separate issue?

[dcominottim]

From my end, it seems the latest beta driver v4311 has solved the issues, @Arturo-Intel.

@akarnokd, if you're not on the latest beta, I suggest you try it, too.

Suggest giving 4314 a try, with the audio stuttering issue fix.

[Karen-Intel]

Hi @Vegas7 have you also tested the latest driver release? v.4314 We also have a new DDU version, can you please give it a go?

@dcominottim if the newest releases have fixed the issue for you, would you agree to close this post?

Thank you and please let us know

Karen

I think we can close the issue @IGCIT
