A strange effect?

[Old Possum]

Hello all

I have noticed a strange effect on my computer with respect to SE-IV and SPWAW
If I start up Steel panthers - world at war
and then shut it down, and then start SE-IV
, SE-IV loads & runs a LOT faster.
The ships just zip acros the map, it takes mer seconds for it to process computer turns.
and the whole game takes about 10 seconds to start from cliking on the .EXE icon as opposed to about 45 seconds if SPWAW was not run first.
My system is a PII-300 running on a 100 MHz board, with 128 M of memory, a 3D- 32M Voodoo 3 vidio card and a SB-AWE16 sound card
The operating system is Windows 95-4.00 with DOS6.22 also present. All settings are set on default except for the CD-ROM which is on maxium read ahead, and the vidio card which is on maxium acceleration setting.
I am also currently playing Baulder's gate 2, Cleopatra, and also use microsoft office 98, none of these programs has the effect that SPWAW has.
Any ideas as to why this dramatic increase in performance occurs?
