Tomb Raider (1996) ostensibly required a Pentium, and I remember (though memory may be faulty) the demo refusing to run on my 486. Does this FPGA 486 support the additional Pentium instructions?

I think I played Tomb Raider on my 486. I also seem to remember I had an S3 ViRGE graphics card, so perhaps that helped

Not require, just recommends Pentium 60 minimum. Like Quake Tomb Raider loves pipelined FPU, 30 fps on Pentium 60 vs 15 fps on 486DX2@66 and 20 on DX4@100.

  • Whoa, you took me back quite a few years there!

    I really wanted a DX4@100 back then but it wasn't available in my area. I "had" to get a Pentium 60, which I was not happy about lol.

    Upgraded to a Pentium 200 MMX. Whoa!

    And then I also got a specific batch Celeron 300a to overclock.

    "Stole" my dad's Matrox Mystique, coz what does he need a "3D" card for? Played "Destruction Derby" a lot, just coz 3D card: https://archive.org/details/dd2matrox_19961205

    Wow, the times!

  • Iirc the only way of getting near 30fps on a socket 3 board is by bumping the bus to 50mhz, having fast cache and a 5x86 and enabling branch prediction and the fpu optimisations. And then wait for it to fault out. Never tried it with an Pentium overdrive though, maybe that will work but those do not like higher bus speeds. Might also be a nice difference in DX4s since the amd and cyrix parts have different fpu implementations to the intel ones.

I remember playing Star Fleet Academy demo on my 486DX5@133 and a Trident 3d SVGA card at slow motion in battles. The game requires a Pentium 75 or 90 and a DirectX accelerator.

  • Wait wait. You’re one of the rare people to ever this odd period of 486 history. What kind of overclocker did you use?
