Mupen64plus+GLideN64 input lag

Usual information below
System: Raspberry Pi Model 3B+ (2017)
RetroPie Version: 4.4, updated all system and emulator components too around a day ago or so
Controller: Original/official PS3 SIXAXIS (BT) over ps3controller driver
The description of the problem
In all N64 games I happen to notice when using GLideN64 with mupen64plus - not referring to the libretro version - there's at least a 1 second or so input lag making games virtually unplayable. Is there any option I can tweak with to fix? I am not using hires version and in fact locked the screen res for N64 games at 720x576 to try and mitigate the issue but this didn't work... using gles2n64 or rice solves the issue

I have the same pi and controller. I don't think I notice much delay between the different plugins, or GlideN64.
here is my config uploaded.

this can add lag as you’re forcing your tv to do an up scaling operation. see https://github.com/RetroPie/RetroPie-Setup/wiki/Input-Lag#use-hdtvs-native-display-resolution
retropie already runs (most) n64 games at 320x240 and then let’s SDL to a (fast) upscale using the GPU.
the rest of the input lag wiki may help you if there’s still an issue.
weird that gles2n64 etc fix the problem but they don’t have accurate emulation so may have incorrectly quick latency to start with? not sure
