My laptop acer swift 3 314-43, with 5500u and 16gb RAM(full specs below) have performance issues in games and some weird readings about CPU usage. All games are stuttering, even with 80fps it feels like I have 15-25 and mangohud always shows âpower throttlingâ, but more on that later.
Of course I checked that on PLATINUM level proton games, that donât have such issues according to protondb, to be sure that itâs isnât optimization stuff. All games have such problem, no matter FPS.
According to mangohud my CPU rarely eats more than 14-18W of power and loads over 35%, but itâs should be more. Also âthrottling powerâ or âthrottling power currentâ always shown.
My TDP limit is 25(itâs set correctly, I checked) and according to youtube tests I should have my actual TDP close to the limit and CPU utilization in games(same games) 10-30% higher. In benchmarks it seems⌠fine. Well, I checked on windows CR23(couldnât find more benchmarks for my CPU with TDP limit of 25) and it had ~same as expected score, then I checked basemark(vulkan, medium) in there and the score was a little bit lower than Iâm getting on manjaro. Iâm making a conclusion that my performance would be the same in CR23(or a bit better) if Iâd run it on manjaro. => benchmarks are working fine. But who knows for sure⌠Itâs 2 different tests. Maybe my integrated GPU works at full power always, but CPU works at full only on WindowsâŚ
And a very strange thing: my performance on battery is same as on AC. Literally no changes. Itâs like my laptop always thinks itâs on battery, even when on AC, and works accordingly(but judging by KDE widgets and mangohud it knows that itâs on AC).
Also might be useful: amount of RAM detected incorrectly. My laptop has 16GB, so itâs should show ~15.6, but it shows 15.
I tried: Changing CPU governor(with a lot of stuff, but on this install of Manjaro itâs Corectrl, I use it on âondemandâ cause itâs performs better than "performance). Reinstalling OS(2 times). Running memtest86+ to see if my RAM is okay(I though that stutter can be a sign of RAM problems) - nothing. Get âPASSâ 3 times and turned it off. Different protons, launch parameters and etc of course, but it isnât the problem, like I said - itâs consistent in every single game. Tried to play with TDP limit, but no matter where I set it(15w,25w,30w) - itâs always about 15 in games and rarely 15-25(in real gameplay itâs only up to 17w 80% of the time).In basemark TDP is higher on ~5w, but still not the limit, should be the limit. Turned of KDE compositor.
I didnât do much with drivers(mesa, etc) cause to me it seems like power management issues(itâs where I spent most of the time, trying different programms).
I hope someone here knows why my laptop canât work at his designed power(Itâs default TDP was set to 25W when I bought it) and only works at 3/5 of it. Why processor is always âpower throttlingâ and why from AC I have the same performance as on battery.
Thanks to everyone in advance.
