[SOLVED] cpu usage limited to 30% while gaming

[ismailsaad]

hi every one !
so i just bought a lenovo IdeaPad L340-15IRH Gaming , whitch has an i5 9300hf 8gb ram gtx 1650 , so the over all performance is good but i just noticed one major problem whitch seems to be really odd, while gaming specialy on pubg or r6s, i get fps drops after like 20mins of gaming not just only fps drop but the mouse allso is lagging like i get imput lag really bad one , i use msi afterburner to see the temps and the max cpu/gpu tems goes to 85° thats good for a laptop i guess, but the issue here is msi indicates that the cpu is running at 100% while in task mannager its dosent acced 30%.
i tryed power mannagent i made every thing high performance the bios is up to date, drivers are also up to date.
does anyone had any issue like this one and found a fix?
thank you all in advance

Sounds like throtteling. Do a stress test on cpu and gpu and monitor temps and loads.

thank you for your inaswer mite,
yes i used intel ETU and i saw that the cpu throttles at 95°
somehow i cant underclock it because i cant change the core voltage

it may just require a laptop cooling pad - or lowering max cpu% in power management to ~95%

Clean the intake and exhaust slots with a brush and strong vacuum if you haven't already then invest in a good power ventilated laptop stand to push cold air into the intake port.

YOu might see if Intel's XTU (which might also allow/enable a core voltage tweak downward) might allow you to specify slightly lower all-core turbo speeds...

Better to sacrifice 100-200 MHz if possible avoid the throttle slowdowns altogether....

also Afterburner is designed to run on MSI products so using it on Lenovo may generate errors in readings. you may want to make sure your laptop is set to active cooling and USB selective suspend disabled
