64k vs 16million colors
« on: January 09, 2021, 09:40:38 am »
My snap install by default was set to 64k colors, but 16m is an option.
But i'm not sure if i'm imagining it but surfing seemed slower when I changed to that.
Anyways, should I leave it at 64k , or would you switch to the higher rating?

Hi David,

Depends on your monitor, and eyesight, and what you use the computer for.
Try both with the attached file, which looks better for you?

PS.. surfing speed would depend on the card, or if you are using an onboard GPU and memory allocated to the GPU.
Cheers

David,
Unless it's old hardware (and therefore slower) I would use the true-colour set (24 or 32-bit).

You never mentioned which driver SNAP is using and whether accelerated. As https://www.arcanoae.com/wiki/panorama/handling-problems/ mentions, using 16 million colours uses twice the memory and twice the CPU as 64K colours. That's Panorama but SNAP depending on the hardware...

My snap install by default was set to 64k colors, but 16m is an option.

The ArcaOS installer always installs SNAP and Panorama at 64K colors. The user needs to change it, every time. Once it is set properly, the setting usually survives driver and OS updates.

I have no idea why they do that, it would seem that somebody, at one time or another, had a problem, so they play safe, and everybody suffers. FWIW, I do have one old DELL system (4300 series) that needs to run at 64K colors, but I think the main problem is that I am using an old TV at 1360x768 resolution, as a monitor. The video adapter only works at 1024x768, 800x600, and 640x480 though (even in win XP, which doesn't work very well). The old TV does run okay at 1360x768x32 on a newer system, so it is obviously the adapter that is causing the problem. That old system is really garbage, and I probably should get rid of it, but it is good for testing new releases of ArcaOS.
