The last time madVR HTPC worked and Envy didn't it was an Envy issue.
And we have not changed anything with the madVR LUT upload.
(Not that means a bug hasn't crept in.)Has Envy change anything?
You will need to test HTPC as well as Envy.
Also test Win32 vs x64 ColourSpace.
Maybe Envy has an issue with its x64 operation/drivers?
And a 256^3 LUT would take a very, very long time, as it will be approx. 100x the resources needed for a 65^3 LUT, and on top will use a lot of memory so there will be a lot of additional disc caching of memory going on. That will add a lot of additional processing time.
