Demon's Souls [BLES00932]

@"Nrgte" : Let the game run for a while. It will compile shaders every time it encounters something, that it doesn't have a shader for. That can cause stutters, usually after a while the game runs smooth. Also if you close the game and start again the compiled shaders will remain in the repository, so it's only a "very first" thing, unless you choose to flush your shaders for whatever reason.

Yeah I noticed that it get's better after a while but never gets to a point where frame drops stop completly. Also de Audio stuttering is prevalent.
