Heh, Rayman 2 PC and I have had a fair history in compatibility. The first computer I played it on was an IBM Thinkpad laptop, and it ran beautifully, though I never managed to beat it on it. Next, was a Compaq desktop, it wasn't built for gaming, and I recall Rayman 2 working fine initially, but it wasn't too long before it refused to run at all, some textures were also missing while it did work.
After that, it was the ol' HP laptop, didn't like Rayman 2 in disc form with Vista and 7. I ended up having to use a VM with Win2000 installed to play it. Come to think of it, that was what I was using when I made this ol' thing:
(Blimey, I was a bit of an numpty back then, eesh)
Eventually, got the GoG version, and everything was fine...'Til I came full circle. Here I am now on a Lenovo, Win8.1, and R2 lags like heck. Still, seeing as it is a more powerful machine, I finally got to emulate the DC version at 60FPS and 1080p, which was magnificent for the most part, sound glitches and lack of music notwithstanding.
