Resolution is the default Doom, 320x200.&lt;p&gt;&amp;gt; To reach the same performance on a PC something like a 486 @ 66MHz and a decent graphics card is needed.&lt;p&gt;Even accounting for the assembly optimizations, it sounds curious that the ZPU would do so much less work per cycle. Does anyone know why this might be?&lt;p&gt;PS. Doom 1 just used the standard VGA mode (13h), and the graphics card didn&amp;#x27;t matter much.</text></comment>
