• 128bit write to vidmem instead of 32bit... just for speed compare... download
  Not restoring textmode is not a deal if you use VolkovCommander, otherwise type command: mode 80

• I don't really understand why is this much faster. You have to do the same amount of operations. Maybe if you could compute 4 pixels at once, and use MOVAPS [ES:DI],XMM0 instead of STOSD , then you can gain some more speed.
  
  btw if you put PUSH AX after INC AX then you can save one byte, because you need just one more INC AX (not two) at the end of the loop.

  :) FPU is in my little finger already but I really should have learn SSE
  
  some little CPU tweaks:
  
  - you can init bank with CWD instead of XOR DX,DX
  - you can use CX for Y coord instead of BX
  then you don't have to preserv BX by PUSH/POP BX pair
  and you can simple mov bl,ITERATIONS instead of mov bx,ITERATIONS
  
  some little FPU tweaks:
  
  before:
  Code:fstp st0 ;frames get rid of s fld1 ;1 frames faddp st1,st0 ;frames +=1
  
  
  after:
  Code:fdiv st0,st0 faddp st1,st0 ;frames +=1
  
  
  before:
  Code:main: ... fstp dword[si+bp] ;s frames ... ;p=(x/W-0.5, (y/H-0.5)*H/W, 0.1) fld dword[si+16] ;0.1 s frames mov word[si+bp],bx fild word[si+bp] ;y-H/2 0.1 s frames mov word[si+bp],ax fild word[si+bp] ;x-W/2 y-H/2 0.1 s frames fild word[si] ;W x-W/2 y-H/2 0.1 s frames fdiv st1,st0 ;W (x-W/2)/W y-H/2 0.1 s frames fdivp st2,st0 ;(x-W/2)/W (y-H/2)/W 0.1 s frames ;p.xy*=s fld st3 ;s p.x p.y p.z s frames fmul st1,st0 ;s p.x*s p.y p.z s frames fmulp st2,st0 ;p.x*s p.y*s p.z s frames fstp dword[si+bp] ;p.y*s p.z s frames fstp dword[si+bp+4] ;p.z s frames fstp dword[si+bp+8] ;s frames
