1.9.2: Read Ahead does not seem to be working for HEIC

Post by Paran902 »

Hello,

I have Read Ahead next image enabled and am mainly viewing .HEIC images which are quite large, over 8000 pixels wide, 15-18MB in size.
I assume that Read Ahead should immediately display the next image if it is cached.

However, it doesn't seem to work that way.
I open the first image, wait even 1 minute, then move to the next image using the mouse wheel and each time I have to wait 2-3 seconds for the next image to show.

I'm using Windows x64 version of XnView 1.9.2.
