VF Jackal! IPL indeed - Initial Program Load. Not many people know that

I was a DB2DBA for a number of years and also did a *bit* of SysProg work.

I take it you have Direct X 8.1? Makes a big difference over 8.0. Not sure about DX 8.2+ because the latest DX mentioned on Microsoft's website is 8.1. Using the correct version of DX will certainly up your frame rate.
I've got a 1.2GHz Athlon, A7V133 mobo, Elsa Gladiac Ultra vid card - and I get 60-80fps ordinarily, dropping to about 40 when a buggered up airfield comes into view and there are lots of other planes/GVs present. My spec is 1½ years old now, and if I can get this sort of performance, I would have thought you could too.
Anyway, back to mainframes. The most efficient IBM utility ever written was IEFBR14.
