@rustymg I quoted this in another thread: "Enhanced Resolution" removed from Pcsx-Rearmed on Recalbox 8.1?:

PCSX-ReArmed is optimized specifically for 32-bit ARM devices, and "enhanced resolution" option dependent on dynarec support, which is only available on 32-bit ARM, and Recalbox 8.1 is 64bit.

If you are using the "Enhanced resolution" option, you are not using Recalbox version 8.1.
Or, you are using Recalbox version 8.1, so you are using another option than rendering at x2 resolution, but the "Enhanced resolution" option is not available in 64bit (and Recalbox 8.1 is 64bit).
