[3DS] [Feature request] XMB Performance on 3DS #16473
Comments
If anything, I believe using a .tar to compress all the assets will make loading slower, because it would have to decompress the assets. XMB is rather graphic intense. You might want to try disabling the background shader and such. |
.tar doesn't compress anything, and the problem is the amount of tiny files... |
This issue is about loading performance on XMB. Tar won't help loading performance, since it would still load the same amount of data from the disc. XMB is pretty hefty, so I'm not surprised it's slow. 800 × 240 is also pretty tight resolution for it too. Try a faster SD card? Disable all the shaders? |
I'm not sure what the new title means, XMB is already supported so I'm not asking about adding it...
I think the bottleneck is the actual console, because on a computer I can quickly copy these small files
As a comment in a similar issue put it:
The 3DS can read a medium-sized 4 MB file relatively quickly, but when trying to read a lot of small files (hundreds in this case), because of the slow access speeds, and inefficiencies of the FAT32 filesystem, it takes a long time to my understanding. |
Description
On my New 3DS, when starting up RetroArch, opening a game, closing a game, and switching cores, it spends around 1 minute on a black screen when using XMB, whereas on RGUI it only takes a few seconds.
I assume that this is because of the horrible SD random access IO speeds, and there are 1421 files in the
assets/xmb
folder, despite all of them combined taking up only 4.1 MB. Could there be an option to package these assets as a .tar and during startup, temporarily load them into RAM?Alternatively (or additionally), it would be great if it would just have to load this once, rather then reloading it when switching games/cores/back to the menu. Since it's statically linked, I'm not sure if this is an option however
Expected behavior
RetroArch loads quickly
Actual behavior
RetroArch takes a long time to do any of these tasks
