When I first installed DisplayCAL, madVR, and Argyllcms, I created my first 3d lut profile and installed it with the i1display pro with no problem. I think I used the default settings to create my first 3d profile to use with madvr with the exception that I used a relative gamma of 2.2 instead of Rec. 1886 for the D6500 temp.
I created two more profiles after that but with those ones I measured the ambient light of my room and adjusted my color temp based on the ambient light measurement. For those profiles I used a gamma of 2.2 relative and Rec. 1886 respectively.
When I tried to install my last to 3d lut profiles I created, the install failed and DisplayCAL said something like there were no good PC to device tables and asked me if I would like to create them for the profile. Creating this tables took an hour and that was already after spending 40 minutes just calibrating and creating a profile.
Why would 3d lut profile be lacking these tables? What can I do about this?

If you want to install a profile that was originally created to generate a 3D LUT, you’ll have to generate these tables.

That sounds unusual. Is this an especially weak machine (CPU, memory)? Even on my seven year old dualcore, generation of high quality PCS to device tables usually takes less than five minutes.
I have an intel quad core 2.5Ghz, 4GB DDR2 Ram and an amd radeon hd 7750. This PC is about 8 years old.
Do you have any idea why I didn’t need to create these tables for my first profile?

These tables are always needed if the aim is to install the profile as display profile. Without them, you’ll get a noticeably bad result, so there’s little chance you wouldn’t have noticed.
I just want to use the 3d luts I create in Displaycal with madVR to watch videos on media players that support madVR. Can I get away with not having high quality PCS to device tables and just having low quality tables without a bad result in this scenario?

Yes, that’s why they are not created by default when you use one of the 3D LUT presets.
