I'm currently running 640x512 interlaced, via Indivision AGA mk3, so I guess I'm good. I've not benchmarked recently, but I'll do tomorrow. Need to connect up my Amiga again, as I've been using the space to test out my Sun Ultra 5. But this seems like a really odd issue, but fortunately one that appears to have workarounds. Great working figuring this one out :)
Interesting vid Dr Chris. Watched “Q” on his channel (Hold and Modify) go about this also. I too have one of those new port holders from centurion tech 😉 Cheers 🍻
I use the Indivision Mk2 and can confirm, no issue with an Amiga Technologies NTSC Rev 1-D-4 MB with an AmigaKit sourced PiStorm32-Lite with Pi4b No modifications to the original hardware at all.
Its like its picking up timings from the monitor and using that to set things at boot. Maybe an NTSC monitor is providing timings out of sync with the PAL crystal and its stalling out causing the lag waiting to sync up? On the old wikipedia I found something called Coordinated Video Timings.
the most important chipmem speed to demos and games (C2P etc) is WriteL. however 31KHz mode etc,. I think that steals chitton of chipmem access killling speedcheck.. my guess: as chipset is designed? Let the scandouble double 15Khz to 31 and it will be fine. independent on scandoubler
@@ChrisEdwardsRestoration think it will be hard to fix. as the chipset steals the cycles.. it is by chipset design this is independent on cpucard. will not blame pistorm anyway

And then I do the same test using my NTSC 1200 with MKIII in and out and I don’t see anywhere near the same numbers. (yes i was running at a different screenmode) Which is why my scores are lower. What’s important is looking at the PiStorm with and without MKIII. There’s not much difference.

On the old wikipedia I found something called Coordinated Video Timings.
i tried it w both crystals and in the end the ntsc clocks fixed w the resolution 15khz modes
the most important chipmem speed to demos and games (C2P etc) is WriteL.
however 31KHz mode etc,. I think that steals chitton of chipmem access killling speedcheck..
my guess: as chipset is designed?
Let the scandouble double 15Khz to 31 and it will be fine. independent on scandoubler
any doubled modes rob it, tried it on the MK3 also, if its 15, shes good, 31=toilet. but they will get her fixed
@@ChrisEdwardsRestoration think it will be hard to fix. as the chipset steals the cycles.. it is by chipset design
this is independent on cpucard. will not blame pistorm anyway
@@ChuckyGang welp crap. at least i know what it is and how to get around it.
Can it be that it is the screen mode itself be far more demanding? I mean you could test double and check the values?
Chris, Are you saying if I just change the Crystal I can change my machine from NTSC to PAL?
yup
The Dell SE2722H does PAL and 15KHz. Micro Center has them for $99.
my DELL as well expect interlace even and odd scanlines wrong order. and interlace is important to me.
@@MrQuuze Which model Dell do you have?
@@Really........ i not fully sure but memory says and quickseach found similar looking one. with code u2410
What if plugging in the scanmagic does not change the access speed, but affects the timer (or calibration thereof), that is used by bustest, somehow?
Its something to do w the timing. All math and science
