Nitro 5 AN515-45 bios version 1.12 has poor cpu perfomance. You might need to downgrade. smh

im sure some people who has this laptop automatically updated bios to version 1.12, because its on windows update. Rather than increasing perfomance and stability, this version make the cpu cores throttling so much that it goes like 1,6 - 1,8 Ghz. Its stutter the fps a lot.

Then, i just downgrade it to version 1.10 and the result is quite good. its stay above 2,0 Ghz most of the time, only cores 3 who often stay at 3,2 Ghz. But, it still not what i expected. I want the cores stay at 3,7 Ghz most of the time like the perfomance on this video a year ago. https://www.youtube.com/watch?v=9bmUK7D1piQ&t=9s

should i downgrade bios to version 1.03 ?

- after future testing, no need to downgrade all way back to v1.03, if your nitro already installed version between v1.04 - v1.10 keep it. Dont update to v1.12. https://community.acer.com/en/discussion/638324/how-to-downgrade-bios-on-acer-nitro-5-an515-43

- If your nitro heating a lot, its because default voltage RX 560X set by acer on p7 are too high up to 1012mV. You might need to undervolt it to around +- ~950mV. You can undervolt the p6 too if you want to decrease more temperature. In my case i set p6 and p7 to 900mV but the whole system crash :v, just set it by a little (try and error). The result is pretty good, temperature decreased from 90C down to ~80-85C, almost 10C lower. https://www.youtube.com/watch?v=jbXgk0eBfOg

- There's no way of undervolting Ryzen 5 3550H. The maximum you can tuning by using Ryzen Controller and set all *TDP (W) below 25 (25 is the default TDP set by Acer). Decreasing tcl-temp are also decreasing TDP. Soo, adjust it wisely.

-  If you are having similar problem like me. Better change the thermal paste and cleaning the fan. afaik, Thermal Grizzly Kryonaut are the best.

NOTE : averything i said here can lead to a -not working state- of your laptop even void your warranty. DWYOR.
