N64 (mupen64plus-GLideN64) performance fix

[dankcushions]

slow-down in mupen64plus-GLideN64? me too. the issue is this setting:

EnableHybridFilter = True

It's a recent addition to GLideN64 that allows better upscaling (less uneven pixels), but appears to be a major performance hit. if you set this to False the performance issues go away (even at 1080p). PR incoming to fix this for future installs, but those of you running current, paste the following into a command line session:

source ~/RetroPie-Setup/scriptmodules/inifuncs.sh 
iniConfig ' = '
iniSet "EnableHybridFilter" "False" "/opt/retropie/configs/n64/mupen64plus.cfg" 

this is now fixed in the RetroPie script, so will be in the next version of the image (TBA). current installs and updates from existing images will require this manual fix.

My default emulator is lr-mupen64plus-next...

Should I change this? Or run the fix?

whoops, you're right. will update post

i think both. -next does not have a setting to reduce slowdown, so it will always be present.
