Why am I getting Pixelated(blocky) shadows on one side of my design

[david.covarrubias]

Im not sure when this started so it might have to do with an update, but I keep getting very nice live rendering on one side of my part but extremely low res pixelated shadows on the opposite side.  I am using a new computer with what I thought was a huge upgrade in every way from my laptop.  The computer handles my files with ease but I thought the upgraded video card would give me better graphics (or at least the same ones).   I tried switching to all three graphic driver options in preferences.  I also downloaded the latest RTX A2000 12GB driver (537.58)... nothing helped

my settings for fusion:

My guess is you need to go into Fusion 360 Preferences and select "OpenGL" as your graphic driver.

Thanks, but I did try each of those options and rebooted the software each time... 

They all behaved exactly the same on this project even openGL 😞

I wish I could remember when it started.  Was it when I bought the workhorse desktop, when I upgraded to win11 or just maybe after a Fusion360 update.  

But it is just with the shadows.  If I go to Graphics Diagnostics and click on "Limit Effects to Optimize Performance" the shading goes away and so does the pixelation, but My graphics card is more than powerful enough to handle this and so is the PC itself...  The file is not heavy, and the computer is not using much of its available resources.  Graphics are super smooth when rotating with my 3d mouse...  That was always the first indicator of a bogged system on my laptop.  Here it is as smooth as can be.  I can't see any reason for bad graphics unless there is a problem in the software.

Is this something I should look for a 1 on 1 with tech support over the phone or is this the type of issue that would usually get resolved on the forum?  I've rarely needed tech support so I'm not sure what is the best way to go about this.
