Hi Bowoadis
We value your contribution to the Microsoft Community. I'm sorry to hear that your Surface device is exhibiting frame drops. Numerous things, such as out-of-date drivers, software incompatibilities, or hardware problems, could be the source of this problem.
In order to confirm that this is not a software-related problem, we will download and install the recovery image on your Surface device if you have downgraded to Windows 10 and the problem still exists. The recovery image is a fresh Windows installation specific on your Surface device.

REQUIREMENTS:
To ensure compatibility with your Surface device, it is recommended to use a USB flash drive with a minimum storage capacity of 16 GB to 32 GB and format it to FAT32. If the storage capacity exceeds 32 GB, it is not possible to format it to FAT32 as only XFAT and NTFS options are available. Please note that if a USB flash drive is formatted to XFAT or NTFS, it will not be detected on your Surface device.
NOTE: Creating a recovery drive will erase all existing files that are stored on the SSD drive. Make sure to transfer any important data on your USB flash drive to another storage device before you proceed.
Once the download is complete, create a folder on your desktop and rename it to ‘recovery’. Extract the recovery image to the folder you created on your desktop. After the extraction is complete, select all the files in the folder and copy and paste them directly to your USB flash drive. Do not copy the folder directly to the USB. Once the copying is done, remove the USB and connect it to your Surface.
