Hi @Justin,
I'm using an ASUS Zephyrus G14 (RX 6700S, R9 6900HS, 16GB RAM)
I attached a test file. I'm measuring the smoothness of moving this GPU heavy object around the canvas. The GTX 1060 used to drag this asset around smoothly (I unfortunately don't have that laptop anymore) but it was very smooth. When using the RX 6700s it's stuttery and laggy despite being much more powerful.
If you need anything else, just let me know. Thanks!

Hi Julio
Background calibration: This adds an offset to each light frame so that the median value in each frame is the same across all light frames. Each channel is treated separately. It's attempting to compensate for the sky brightness changing over the course of the night.
Subtract black level: Normally when we open a RAW file we subtract a black level which is an average of the masked pixels around the edge of the sensor. If dark frames have been specified then this step is unnecessary and can be skipped by unchecking "Subtract black level" if you think that it's causing a problem. 
Regards
Justin

Hi Brad
We've fixed a bug that was probably causing your issue so you might want to try it again when the next beta is released, which shouldn't be too long.
Cheers

Brad, could you try turning off hardware acceleration in Preferences|Performance please?
Thanks

Hi numberonesoniafan
Thanks for reporting this. I'm not sure exactly what's wrong as yet, but I note that if I change the format to RGB/32 (HDR) before converting from the scanner profile to ProPhoto, then it seems to work correctly.

Hi NotMyFault
If you disable "All layers" in the selection brush it will be quicker. The "All layers" option requires rendering the noise reduction live filter, the lab curves and the gaussian blur filter effect at full resolution for at least some of the document, which will take some time, hence the delay. You should only turn on the "All layers" option when you really need it, i.e. edges are derived from multiple layers. In your cut down document all the edges are derived from the one pixel layer, so maybe you don't need "All layers".

Hi nomi02118
The file is a panorama merged in Lightroom but we are treating it as an out-of-camera RAW file and applying lens profile corrections when we shouldn't. As a work around, in Develop go to the 'Lens' page and turn off chromatic aberration correction and the other lens profile corrections.
Hope that helps

There will be an option to use the old filter. I will seek to make improvements to the new filter in the future.

Hi Mike
Can you post a sample image, please?
Thank you
Justin

Hi Steve
Thank you for posting your image. I agree you can get a better result on this image using the old filter, which is disappointing. We will reinstate it as an option in 1.7.2.
Cheers

Hi Steve
Can you post some sample images to illustrate the problem, please? If you include the original image I will do some tests.
Thanks
Justin

No, I think it's just that one

Yes, I can reproduce this. I'm not sure what the problem is yet but it will be fixable.  

Hi Hanterdro
I believe this has now been fixed. Thanks for your help.

Hi j3rry
Good spot. This has now been fixed.
Thanks
