How well will it run on slowest hyperthreading p4 or pentium d?

I've run lots of gzdoom on old hardware, even 700mhz p3 with opengl 1.0 card. This is probably more demanding than most of the games in this release. Maybe a couple of the 3d shooters would struggle on this?

I guess its not inconceivable that Commodore OS could run on a P4 or Pentium D (which would be at least 15 years old), but I certainly would not recommend it.
