Pi OS 64bit running on a Pi 4 4GB

A bit more experimenting this morning. My suspicion about VNC was incorrect. I made these changes to the /boot/config.txt file.

Uncomment the following lines:
framebuffer_width=1920
framebuffer_height=1080
Note: you can change the resolution here to suit your needs.

Uncomment this line:
hdmi_force_hotplug=1

Comment out these two lines:
#dtoverlay=vc4-kms-v3d
#max_framebuffers=2

After a reboot, Conky started on the right hand side and Chromium was no longer sluggish. My new guess is that something with the dtoverlay causes Chromium to be sluggish in a VNC only environment. What I don't know yet is what side effects may exist by commenting out the dtoverlay lines. If I run into any, I'll report them. If you guys run into any, please report.

As always, I recommend backing up your pi before making changes....just in case. I made a goof in my initial edits of the config.txt file which left me unable to VNC into the Pi. Had to ssh in to fix.
