But still, during the time of Windows 95/98 I could hardly play even a 128kbps MP3 with WinAmp in my Pentium 133MHz with 12MB of Ram where I had got rid of lots of bloatware. At the same time I could play it smoothly in Linux with a full blown desktop environment (Window Maker) running. So it was a bad performer in comparison even back then.
