Probably because the textures were just too low resolution. You add bilinear filtering to low-res textures, you get something that looks blurry.

Yeah, the texture memory was anemic. 4KB total. If you had mipmapping on, that ate half leaving you with 2KB which is only enough to fit a single 32x32 pixel texture at 16-bit color.
