Thanks for the thought Boris but after much searching I have identified the program as Ultimate Race Pro.
The thing is though it dosen’t look quite as Ultimate as I remember it !
This was the first program I ran on my new 3DFX Voodoo 2 graphics card and I was seriously impressed but looking at You Tube video of it now shows its age.
I remember I liked the physics and control system too but I can’t test that out because although it can be downloaded for free no one has been able to make it run on W10 with a modern graphics card.
Oh well ?
