Alright, so anyway, I just upgraded my DOS machine to an AMD 5x86-133 (OCed to 120/40FSB), and 16MB of EDO RAM. Well, considering the specs of this thing, I nailed it down to the sound card. My current sound card is an official Sound Blaster 16 ISA card. This is NOT a knockoff. It's the official Creative Labs card. And it sucks. When I enable Redbook audio in Descent II, my framerates double because the synth chip (OPL3), is not being used. And any game that needs an assload of sound channels to run dies and putters in heavy combat, both sound wise and framerate wise. I played Descent for years on a Dell Dimension P75T, and it had similar specs to this box but with a Turtle Beach sound card, and it never dropped below 60fps. On this machine, I ace 20 - my 486-25 Thinkpad ran it better. So, any recommendations? I have SETBLASTER enabled in autoexec.bat, I've got both DOS and Windows drivers loaded, and my games run like crap. The card I want to replace it with *MUST* be 100% SB16 compatible. My machine is running PC-DOS 7.0/Windows 3.1.
