Cache Full ISO in RAM Question

RE: Cache Full ISO in RAM Question
Then probably "as fast as it gets" isn't fast enough and you're just getting slowdowns whenever a lot of new things are processed not when "they are loaded". Vulkan backend will likely help in here once it's done, caching iso to RAM will not.
As a matter of fact games can be broken even by the slowest hdd's speed which is still faster than UMD they expect, hence we need option to simulate umd delays and it does NOT cause slowdowns in any game.


Caching iso is neither a debug nor a performance option, it really only helps on storage with motor that completely stops after certain time on inactivity like power saving hdds(which aren't really all that common) or pretty much every modern CD/DVD/BD drive.
Just for a complete list will also mention a bug happening on Raspberry Pi which could kill IO performance and that's another situation where this option was helping, none of that code ever affected Android nor Windows through and the problem was already fixed.


Apparently all Rockstar games are pretty good at abusing PSP power and so are at least in some places/moments much harder to emulate, you can drop graphic enhancing features down/off(like rendering res or even post processing shaders) or/and use auto frameskip to help it through those more demanding areas.
