Acer Predator PHN16-71 not working well after reinstalling windows 11

rajchauhan28

I purchased Acer Predator PHN16-71 recently and while after dual booting Linux i messed up some of the partition system and efi partition by mistake so i have to do a fresh windows 11 install (deleting everything and performing a new install) but after reinstalling windows update didn't added all the drivers so i installed them from acer product support after installing them everything is working fine but when i launcher Minecraft/call of duty warzone etc games of mine there is a significant fps drop.

Like before reinstalling Minecraft was on 1100 fps average but not only 600 to 700 fps and warzone was 120 fps + without DLSS but now around 100 or below

I Checked the drivers and apps installed in my friend's Acer Predator PHN16-71 but can't find anything.

If there are some settings like registry edit, some additional softwares or system settings please help me.

Or Can i go to Acer service centre or Croma (from where i purchased this laptop) to get it reconfigured by them??

Why did you reformat the boot drive and Clean Installed Windows11 on a brand-new Windows11 machine that was working fine? All you had to do was click on Reset in Windows11 and you would have kept the factory default settings and original Acer drivers. I recommend bringing the laptop to Acer Services in your country to reset the system to factory defaults and install OEM Windows11. There may be a small service charge of $25.

After reinstalling Windows 11 on your Acer Predator PHN16-71, you experienced FPS drops in games like Minecraft and Call of Duty Warzone. I have also faced this issue, but now it's resolved. To resolve this, try the following, But I am not sure which step will work for you. 

Update graphics drivers from Acer's website or GPU manufacturer. 

Run Windows Update to install missing drivers. 

Set the power plan to "High Performance" for gaming. 

Check for BIOS updates on Acer's support website. 

Close unnecessary background apps while gaming. 

Monitor laptop temperature to avoid thermal throttling. 

Update the games to the latest versions. 

Check in-game settings for performance tweaks. 

If the issue persists, contact the Acer service center or Croma for further assistance. Back up important data before seeking help. Be cautious with Windows Registry edits and backup before making changes.
