Try uninstalling Support Assistant. On my R7 and R13 that solved the issue on both machines. I know others on here have had the same issue and fixed it the same way. The R15 is not that different to an R13.

Uninstall all DELL/Alienware software software and see if that solves the issue. Lots of posts on this forum with AWCC, support Assist software causing issues.

Then reinstall 1 by 1 until the issue appears again.

i think that worked! fingers crossed. no issues so far in a couple hours worth of gaming =] 

thank you! just tried this! fingers crossed. have been playing some games for a couple hours and no stutters!!!  

I have learnt with my R13 my machine runs better when I set the lights, remove the AWCC and then uninstall Dell's software that i am never going to use. I also try not to use Dells drivers. For example I use Nvidia's drivers for my graphics card.

Enjoy your new PC.

I’m having exactly this same issue that you described, every 10 or 15 minutes or so. Not even when just running games, even just at merely being on the desktop and playing music or chatting on discord or something. 

I’ve tried uninstalling support assist, Alienware command center, every single thing that says Alienware in programs, but still the problem is persisting.

Well, I take it back! I had thought that I’d uninstalled Support Assist, but I guess I either didn’t complete the process, or maybe AWCC put it back (Which I have now uninstalled as well). In any case, I noticed that Support Assist was still there this morning, so I uninstalled it one more time. It’s been a whole day now, it remains uninstalled, and more importantly, there has not been a single instance of the stuttering since then. So, the fix works! Very very thankful for this!

Glad that works for you as well.. ! Cheers!

Just wanna say I had the exact same stuttering problem and the exact same Aurora r15 specs as the original poster. After spending hours trying everything, I found this post and uninstalled SupportAssist (make sure to uninstall SupportAssist AND Dell SupportAssist, I had 2 separate apps), and this solved my stuttering issue. It’s pretty ironic an app meant for diagnosing pc issues is actually the cause of pc issues!

ive tried all of these options and i have an R 13 and its still persistent

That's how I run my R11 rtx 3060 Ti.  No Dell software or drivers.   I did try one time to see how the Dell graphic driver worked and it caused all kinds of stuttering.  Restored my configuration with Macrium and no more stuttering problem.

i uninstalled both SupportAssist and Dell SupportAssist, stuttering is a lot better but still persists a bit, i still have a lot of Alienware stuff, should i keep uninstalling?

Hi. I am here with all of you. A new owner of an Aurora R15, and yes, I have these HORRENDOUS stuttering issues about every 15 minutes. I spent a lot of time tonight investigating this. I watched the task manager and figured out that the CPU usage spikes up to 100% about every 15 minutes due to Dell related services/applications.

My OS, BIOS, firmware, and applications are ALL UP TO DATE.

There is no explanation for this except for Dell's poor software. It is not a hardware issue.

The only extra tip I can provide, beyond uninstalling ALL of the SupportAssist apps on your machine, is that I noticed the CPU usage spikes are slightly less severe if you turn off the "System Repair" feature in SupportAssist. This simply further confirms that SupportAssist is the problem and it should be uninstalled totally.

Uninstall the 2 entries in your screenshot that have "SupportAssist" in the name. I don't think it's fully removed from your machine because there are *three* different SupportAssist things to uninstall for some insane reason.
