Sure it can! Though it will probably not run very well
Not that it ran very well on a 80286 with ega graphics either, which is basically the specs of the pcs back then.


Yes it did, I remember playing it very well, and finishing it in 1993 in my 12Mhz 286. But I also believe it depended on the graphic card you had. At that time I was using a 256KB ISA Boca VGA Card, that was fast but had some bugs with some software I used. Later replaced it with a Tridend 512Kb TVGA9000 (SVGA) and the newer card was slower than the older one in DOS (but much more stable).

And don't forget that this game was much lighter than Doom (this one required a full 486DX to play really well if I'm not mistaken).

The problem with PCs is that you can't simply measure it's performance based on CPU alone. Back then (and still now) many Top model PCs (with the fastest CPU) were sold with crappy SVGA cards. I remember seing a friends 486DX2 at 66 Mhz bought in Dec 1992 equiped with 420MB HDD, 4MB of ram and then a wimpy 512KB trident TVGA9000, instead of a good ISA SVGA card like a S3 with 1MB or 2 MB of Vram (this was before Vesa Local BUS).

I remember in 1995 having a cyrix 486DX at 40Mhz and 4Mb of Ram and when I replaced the SVGA card I was using (the same TVGA I had in the previous 286) with a VLB 1MB Cirrus SVGA card, the 3d performance in some games almost doubled. Red Baron comes to mind, since I had to switch off the turbo (and run at 25MHz) and sometimes disable the internal cache also to get the game down to a decent playable speed (this same game still crawls in my amiga 1200 equipped with a 40Mhz Apollo 1240 and 64MB of Ram).
