Hello so i've tried everything almost:
- tried to install all drivers from ASUS site / tried to use last drivers
- tried to mess with nvidia control panel, seems nothing can remove those stutter
- tried all the sub-reddit and reddit about the SCAR 18 and 4090 mobile probelms, seems nothing has fixed it (just make it better but i can still stutter)
- tried to unistall all asus bloatware (also not-asus bloatware) included armory crate but doesn't change anything
- tried ULTIMATE + TURBO / and other profiles (not manual profile as i dont want to break anything)
- tried different games and the stutter is different, it is more visible on Apex Legends and other games, but Starfield is still visible but not that much
The stutter is not normal, it's like a micro-stutter that happens every 5-10 seconds for 30 seconds or it happens every 1 minute or 2 minutes, not always. Can't find what the problem is.
It's all playable but you can definitely notice those stutter by playing, let me know if someone know what cause this.. thank you
for sure you must use Manuel Profile for better performance check this link and make a manual profile
this manual profile apply on the fans and the system so first from the link make a manual fan profile after this you can try again in games becouse from HWINFO64 that i see is the CPU has throttle and than also can make a shutter in hight fps game because your GPU have the power but when the CPU throttle he lower the frequency and that can make a problem
when you make a custom profile and test it if you have again a problem chech the temperatures again you musnt see any red numbers that is overheating you can buy a cooling pad to improve the performance and life of your laptop
you have red numbers and your CPU still overheating you can try to limit you CPU power from here
make this you thing to 100W or 110W and try to play if you have problem again try to lower them to 95 and also after every tests whit diffrence watts reset your HWINFO64 and check the temperature for every setting that you make
i am not 100% sure is that the problem but your CPU overheat and that limit the performance when reach current temperature after the cpu hit temperature limit you frequence drop when they drop the cpu has cool little bit and again start to work at max after this again hit thermal limit and you CPU go non stop to this cicle so try this and write again
also be sure you Nvidia drivers are updated
and from Nvidia control panel reset the settings that you try becouse you can mess something from there
use maximum performance from the pannel
for example you can see my HWINFO whitout reseting for 7 hours also i play 5 hourse in that time
max CPU temperature is 86
max GPU temperature is 71
try what i write and you will see some performance and better work i have hope when you make your custom profile for better fan speeds and try to limit little bit your CPU power to prevent overheating that will fix your problem but first try to make only custom fan profile like is in the link and if you have problem then try to limit your cpu and in every limit that you apply test it in games try whit 110-100-90 or 95 try some combination to see what will happen and buy a cooling pad that is still important
My rig is lower class Strix G16 G614J
In that case when you try almost everything you can try what "Scar16_4090" say do to clean windows install and test the system again
If you have some information on your PC you can do windows Backup file and restored after this
For armory crate custom fan profile and cooling pad is better to use it on every laptop you have to improve your temperatures
For Armory Crate fan profile for every laptop is different and you must try to abjust the fan speeds for your laptop
Also if you cant install clean windows 11 i thing the factory reset will do almoust the same but if you can make clean install do what "Scar" man told you and after the test dont be afraid to install Armory Crate becouse i dont think your stutter come from there
