Retroarch menu lagging

Hi all, I noticed that whenever I hold down on a playlist the menu items begin to get very laggy and stuttery, I knows it probably due to the size of thumbsnails. My question is what are some of the ways you guys reduce the file size of these images to reduce lag.

Thanks

do you have on-demand thumbnail downloading enabled? if so, the lag is probably from downloading the thumbnails from the internet.

Hmm not sure where is that under?

Nvm i found it, was already turned off.

If you don’t mind reducing the quality (slightly) of the thumbnails, you can try pngquant:

Thanks I’ll give it a try
