With just facial tags, handles, eye tracking etc. animation is very smooth with no noticeable lag. As soon as I enable body tracking thing start severely lagging and animation becomes very choppy. Is this normal and is there a setting to tweak performance for this?

Yes, it's processor-intensive. Body tracking takes up a lot of resources and will work best with devices that have our minimum specs or beyond. If you try body tracking and see the framerate in the lower left corner turn orange, that means either the puppet is complex enough to be causing strain or your system is struggling to meet that framerate. The options around this are to lower the framerate, simplify the puppet, or test on a higher spec machine.
Ok, so its a fairly new computer with 32 gig of ram and an 10th generation i7 (Intel Core i7-10710U) running at 1.10Ghz.
About 400 gig free space on the main drive.
The graphics are just intel onboard (Intel UHD graphics) perhaps that is the choke point.? I need to look into where I can find whether or not it supports OpenGL 3.2.
couldn't find anthing about open GL but this is some info on the onboard graphics
I'm not a hardware expert but at quick glance those seem like they should work.
If you try to body track with the example stick figure character from adobe.com/go/ch_bodytracker, what kind of framerate are you seeing? For me on a 2016 Macbook Pro I usually get between 15-24 fps with body tracking on.
