PPC CPUs Speed by Ranger question

Snake79 · 15 January 2015, 19:39

Hi there.
How much real are readings by Ranger about CPU Speed? Isn't 100MHz of Blizzard on A1200 PPC config too low? (A4000 has 266MHz)
And another question by the way... Is it because of Picasso IV, windows are drawing so slow on A1200 PPC config? or its CPU/IDE? (A4000 PPC is very fast and responsive in that matter, with SCSI especially)...
PS. PowerPC 603e are in 160, 200 or 240 MHz variants by: http://en.wikipedia.org/wiki/PowerUP_%28accelerator%29
Thanks!

I don't know and don't really care, as usual.

But to confirm if it is QEMU issue, you can try forcing CPU model to CSPPC by adding "ppc_model=604e" to config file. (EDIT: or any other QEMU supported PPC CPU model)

EDIT: Wrong frequency may be as simple as wrong multiplier bits configured but unfortunately your screenshot does not show any low level CPU information.

"ppc_model=604e" change nothing, still have 603e, the results are the same.
Tried to edit other values (in confront to a4000 config), but without success...
Well, i understand that QEmu side is not your part, but thanks for reply.
Fortunately the A4000 Cyberstorm PPC config is working fast, storm like

Thanks!
