Any chance your issue is the same as Extremely weird dGPU power behaviour on 140W chargers (moved)? Seems like a lot of 140W USB-PD chargers and Framework 16 laptops don’t negotiate power in a friendly way, Baseus chargers being the exception.
i contributed to the Github Issue, as i wrote about “jumpy” GPU Performance since the Introduction of the 3.05 Bios
It looks like it could be related, at least with what I’m seeing regarding the symptoms.
Edit: Upon further reading it looks like it could actually be the same issue. I think the presumption was that with a higher wattage charger the battery draw and power fluctuations would be non-existent.
It literally is the same negotiation issue. The baseus works wonders, but the UGREEN Nexode 160W and the Delta 240W show the same symptoms.
Unstable dGPU power, a lot of stuttering.
I have recently filed a git issue that seems to be similar to what you described (and plus some more). I did some testing and if you and others see similar results to mine it would point to PD being wonky rather than GPU problems.
Yes, the problem is probably the USB PD negotiation. The thing is, you need the dGPU to be installed and under stress to replicate the issue, because the CPU power delivery is flawless. The problem only appears on the dGPU in combination with some >=140W power supplies.
It’s like the laptop has a hard time allocating the PSU power to the dGPU… Weird.
not necessarily, there might be a case where A) CPU doesn’t pull more then 60w so it can get all the power from the battery meaning the power negotiation/plan is simplified and only factors in the powerplan set systemwide. The GPU can easily draw more than the battery max output and needs to know what is the connected charger wattage. B) i forgot what case B was while writing case A :-p
Just receive mine, I get what you guys are talking about…the gpu power consumption is truly in a roller coaster way…gaming on performance mode is a disaster with tones of stuck. I feel like the tdp is jumping between 120 to 145 while the battery is charged a little and discharged a little. (Mine laptop pull ~5w out of battery on 145w tdp)
Hope they could fix it soon.
Just saw a CES announcement for a multi-port USB-C charging brick that supports 500W total, with 1 port supporting 240W.
