Unfortunately, I don't think you're going to see any improvements in future versions, and might have to roll back to 2.80 or whatever was the last working version you had, it looks like you're GPU might not be supported anymore.

The official Blender system requirements, list a minimum of Geforce 400 series cards...

... but I did run across this ...

Supported GPUs in Blender 2.80

,,, which says 2.80 may work on Geforce 200 series cards, but that's with some band-aids in the code, and reading between the lines, it looks like they're phasing support for those cards out. The work-arounds could have caused problems with newer stuff implemented in 2.81+ and had to be dropped or may just have been oversight, etc, which could explain the issues you're having in the newer versions. I'm just speculating tho. You might have a read thru the comments section there, see if anyone mentions similar problems to what you're experiencing.
