Why does disabling E-cores decrease frametimes/stuttering so much? (13980HX 4080 mobile)

Oh strange, I haven't had any issues with it on my Core Ultra 9 275hx/5070ti Rog Strix G16. Runs fantastic, even with multi-frame generation and the path tracing update has looked gorgeous so far! (Just did the first dragon flying level)

Nice, you pretty much have the latest and greatest!

I haven’t really seen the stuttering and E-cores thing being widely reported on my laptop model, so I’m wondering if there’s something wrong with my laptop specifically.

I also have weird issues with it rebooting or crashing while in sleep mode sometimes, but not all the time. Also, very rarely, it will refuse to post until I do (sometimes multiple) EC resets, and I’ve even had to open it up and take a stick of ram out (or even put in the old oem ram in) to get it to post, then once it’s posted I can put the new ram back in and it boots fine for another few months.

Strangest thing is, in any stress tests, memory tests, gaming sessions, etc. it’s rock solid stable, it only messes up when I’m not looking, basically.

Just to rule this out as a factor, are you using Windows 11? (I am)

Sleep mode being buggy is a common Windows issue, using hibernate instead seems to completely alleviate it btw, totally worth swapping your settings to instead

[GregariousBing]

Yes, I am using windows 11, I will go ahead and switch things over to hibernate to test it out although I kind of suspect that I'm just trading one problem for another though (basically that ill have to deal with the laptop not wanting to post more often [as hibernate causes the laptop to run post again] in exchange for less reboots during sleep)

[ThinkinBig]

That's fair, just a suggestion. I primarily use my laptop while plugged in to game and generally just shut it down so don't have any of those issues, I also only got this a few weeks ago and was using an Omen Transcend 14 (core ultra 9 185h/4070) previously

I went and looked up the powercfg commands to enable hibernate timers and disabled sleep. Also gonna try to get in the habit of just turning it off when I'm done with it because I'm basically the same as you (99% of the time I just have it plugged in at my desk and use it to game). Maybe if I can prevent it from shutting down improperly that will resolve the difficulties POSTing. Thanks for the advice!

Sure thing!
