I have just generated a 500^3 LUT...
Yes, that is HUGE, and really has little practical use.

But, it has become possible as we are very close to releasing a new ColourSpace version that is x64 based.

The real benefit is that with an x64 version of ColourSpace we have again expanded future possibilities for all of ColourSpace's capabilities.
There will be differences between the Win32 and x64 versions, as not all supported hardware has x64 capabilities.

More info, and more associated new developments, will be announced in the coming days...

This is actually hard to believe, but I have just generated a 1024^3 LUT...
That is absolutely massive!
2.5 hours processing on my desktop PC, but a valid LUT was indeed generated.

Steve

Just for info, as part of the ongoing ColourSpace development work we have made some additional major changes to the Colour Engine within ColourSpace.
This will further increase calibration accuracy, especially when combined with the additional benefits of ColourSpace being x64 based.

The information within the LUT Size page of the website has been updated to explain in detail the benefits of generating larger LUT sizes, even when the Uploaded LUT is smaller.

Steve

It is also worth saying that we are seeing a potentially significant increase is operation speed for the x64 version of ColourSpace.
The gain is obviously variable, depending on the ColourSpace operation being performed, but is there regardless.

Combined with the additional Colour Engine improvements, this is shaping up to be a really significant update for all calibration performed using ColourSpace,

Improved color engine? You have peaked my interest! When will this new version be available? I am very interested in trying the new color engine as I have not measured an improvement when processing above 33^3 LUT for LG oleds compared to doing a 1:1 native 33^3 LUT.

If the LUT Generation Size matches exactly the LUT Upload Size the benefits in using a larger LUT Size will be minimal, but there will likely be some improvement due to at least to Nyquist sampling.
This can be seen in the linked to LUT Size page.

The Colour Engine improvements are separate development, and are actually (potentially) a significant development.
The first release will have v1 of the new Colour Engine changes, with additional change following...
(It may actually be that the 'additional' follow-up changes are an even greater improvement..., but we need the v1 changes to be completed first.)

The speed increase is also significant.

Keep an eye on the Forum for an announcement on a Beta Release, hopefully very soon.

The user will need to choose one version or the other depending on the meter used, or will it be completely transparent?

Most, if not all viable probes have x64 capability.
(Spyder is one that we do not have x64 drivers for as Datacolor seem to not care about 3rd party integration any more...)
It will more likely be other/old hardware, such as some older monitors, that will lack x64 support.
We will likely just drop any non-64 bit hardware.
No point in supporting such old systems.

Hi Steve,

Great news on the x64 update!

Has the new version been tested on Apple Silicon (M1/M2/M3/M4) Macs running Windows 11 ARM via VMWare?
Specifically, I'd like to know if there are any known issues with the x64 emulation or USB probe passthrough.

No idea - testing will need to be done.

Steve

Tested i1D3 and CR probes on my M1 Mac.
And an ASUS monitor.
All work fine.
