Inspired by this question about the CPU frequency when booting the Amiga in PAL vs NTSC, I'm curious if the CPU frequency was affected by using the other display mode.
In other words, I used an ECS Amiga in North America, thus booted as NTSC. To get a little extra vertical real estate on my screen, I would run Workbench with a PAL non-interlaced mode. My A1960 monitor happily synced to the 50Hz vertical refresh rate and I enjoyed a few dozen extra lines of Workbench height.
So my question is, was my CPU running a touch slower as a result of this, or did the selection of display mode on an NTSC-booted Amiga not adjust the CPU frequency?
I'm presuming that the Denise chip's display mode wouldn't impact the CPU clock, but I'm not sure in this case. I am assuming based on the linked question's information that when I would run some games in PAL mode (I had a well worn 'PAL Booter' disk close by at all times), THAT would impact the CPU frequency. But a simple Workbench display mode selection? Presuming not...
FWIW, I had an A2630 accelerator and would be running the '030 typically, if that has any impact on the answer.
