Set L Speed Profiles to Balance Mode and
Set Resolution to 1080x2220 (FHD) or 1480x720(HD)
Performance -
If you want to increase +10-15 fps while playing games then follow the instructions.
1st - Flash Custom Kernel
By flashing custom kernel, there is high chances to increase performance of your device.
These are my recommendation,
For Lineage OS/AOSP based ROM use RZ Kernel.
For oneUI (9 above) based ROM use Phantom Kernel.
For samsung experience (7.1.1-8.1) based ROM use Zceed Kernel.
