#689 Bad performance in DOS

[mats]

I'm using doom legacy 1.41 under retroarch (lastest version that supports D.O.S.) and no matter the cycles i put i get some slowdowns in the game, the music in between levels gets all stuttered always and when i quit the game and shows the Y and N message also happens there

i play the game in 640x480, is there something to improve performance?

What is the emulated CPU speed?
Which emulator core are you using within Retroarch for MS-DOS?
What platform are you running Retroarch itself on?
