I’ve been testing the dGPU and noticed the power draw on battery can be significant while gaming (~20W). I was curious what would happen if I just ignored that and let the laptop continue running. What I found is that the laptop doesn’t die, but it appears the power limits will adjusted when the battery reaches ~30%, resulting in the battery actually charging up again. This seems like an unnecessary battery cycle, however it does mean you don’t have to continually change your power draw and game settings to continue your session, just let the built in controller do it’s thing.

Or, if you run Hyper-RX Eco mode and Best Power Efficiency in Windows power profiles you will never discharge and never have any settings change automatically or otherwise. Every game I’ve played including newer resource hungry ones like Space Marine 2 and Starfield run just fine like this.
I’m on Linux, but I’m sure someone will that information useful so thanks for sharing

Well that the power profile adjusts while hitting 30% is pretty standard, but you are reducing the Systems performance by alot at that moment. I could play on balanced with the game beeing at acceptable settings all the Time without the System discharging, but why playing on max performance with higher presets to just hit best battery at 30% and beeing unable to play further.

Does Linux not have AMD Drivers? Hyper-RX Eco is part of the AMD configuration so you should at least be able to use that? Does Linux not have a way of optimizing itself for best efficiency? I’m sure there are similar settings available in Linux.
Hypr RX eco is just forbidding the dGPU to be used, that can be done by commands. Linux itself is far more ressource efficient than windows. But its not the point of the topic that was shared here. Don’t need no 180w power brick to power the fw16 running on the iGPU nor worrying about it depleting the battery.
I’ve managed to pull up to 20W from battery while on the balanced ppd profile, which I why I decided to see what happened when I just let it die. Obviously there’s a performance hit yes, but personally I’ve been unable to tell when it switches power profiles while I’m gaming, and I’ve played for long enough that it’ll have switched a couple times.
That is not correct, Hyper-RX Eco is tuning the dGPU to use power more efficiently. AMD SmartShift Eco uses the iGPU for mobile gaming to really save power.
