Pre-emptive Shader Caching - Possibility?

Not possible

Thats too bad.  I thought it would be possible if save data were used to have RPCS3 precompile the shader cache by loading every save spot, compile the shader cache and when complete move onto the next save.  But then again I guess the user could go through that process by themselves if the there were a file for each game of every save location.  Might not be perfect if an area does not have a save location, but using that strategy I would assume it could be implemented into RPCS3 if the work were put into it.  Or is the save data copyright material?
