XMB Shadows causes lag on Rpi3

RetroArch Linux devices
#1

Hello,

I’ve been experiencing an issue with my Rpi3 ; using Raspbian Lite with nothing installed but RA, the XMB’s drop shadows are causing lag when navigating, especially when there is a lot of text displayed. When I disable the shadows (by going into Settings > Menu), the XMB is fluid again. I’ve installed Lakka and it looks like the menu is fluid here, but I didn’t pay attention if the shadows were there.

Is this normal, or am I missing something ? Here is my --features dump :

#2

Yeah, it’s normal. The text shadows and the ribbon background can both have significant impact on performance.

#3

Okay, I see. The ribbon is working fine and looking beautiful for me, but the shadows are just killing the fluidity. That may would be a good idea to enable them only for icons or titles tho.
