Very nice to see people are actually still playing SH !!!
I thought I was one of the dinosaurs still playing this.
My friends, the problem is not with the graphics card. It's about memory and Windows compatibility. I had purchased SH CE, only to find that I could not run it in any version but Win98...
I couldn't solve this, so, I turned to DOSBOX and another DOS emulator I cannot remember right now. DOSBOX actually worked for me

, playing the game with sound and without the speed issue I experienced with another emulator.
I will post here a system configuration when I return home, unfortunately late at night...
A jewel in sub simulation world, glad it's still alive!!
