Sometimes, we're shocked by how bad old games often are. But it takes a special kind of bad to be this bad. This is Virtual Hydlide, the 1995 3D sequel to an ancient NES and MSX game that nobody remembers. It was bad at the time. Now, it's absolutely shocking. Just look at the poor old Sega Saturn attempting to render a forest of flat trees, flat ground AND a castle. Ready for 5fps action?
It's a well-known fact that the way to get the best performance out of a Sega Saturn was to write code specifically addressing the two different processors inside the machine, usually sending 2D graphics to one and 3D to the other. I have a sneaky suspicion that the code here was written to directly address the processor of a ColecoVision. In another room. Via sign language sent as polaroids... by second-class post.
Bear in mind that this game would have retailed for £50 when it was new. Have you seen any full-price retail games with worse frame-rates than this? And no, PS3 Skyrim doesn't count. I challenge you to find one... then let us know in the comments.
