Are you using CD-ROM, DVD-ROM or CD-RW, DVD-RW?

Hello JSO. I am using virtual images of the games and using daemon tools.

I can see two possible issues. One is that playing CD audio from an image will have a much higher CPU cost than playing it from CD, which is free. What are your system specs? Another possible issue is the fact that your hard drive is busy playing the CD audio, leading to stutters when it needs to access game data. Perhaps putting the CD images on another hard drive, on another IDE channel, would help. Also, check if DMA is enabled for your hard drive.

Hello Oetker. One thing I noted was that not all CD audio based games are stuttering. For eg. Interstate '76 is smooth with virtual disk. Same with nitro pack. As of now noted that the issue is more pronounced in Midtown Madness and a little less on Fire Fight. Interestingly the stutter is present even on the vehicle selection screen in MTM (where the vehicle stutters while revolving). Will check on the DMA part. BTW the system config is in my signature. Thanks!

I remember having a stuttering problem way back when I played Carmageddon 2. It stopped when I put in any cd with audio tracks. But as you already have sound it probably does not work..

Been a while, but recently enabled DMA mode. Then noticed almost no stuttering using Daemon tools. Enabling DMA did the trick. Thanks!!
