I have a strong rig and play with every aspect of the game modded, so it's a pretty heavy load: running from an external HDD with the image mounting process it takes 16 seconds to prepare ff7 to launch and 68 seconds to actual start at the first execution. Total 124 seconds.
Launching it a second time tough reduces the waiting time quite a lot: 5 seconds of preparations and 62 for the actual start, total 67 seconds.
I guess that using an internal HDD or even an SDD should reduce the waiting times quite a lot. 30 seconds look pretty fine to me.
Reducing the number of mods I can get up to just 15-20 seconds for the whole process.
