Blocky and slow display

[dleberfinger]

After about an hour of being upgraded to ACADE 2021 my display suddenly went haywire. Please see the image and screencast below. When zoomed out, there is no detail available. Even when I zoom in to see the text it still has a horrible appearance. Panning and zooming in and out is generally laggy and not as responsive as it was in 2020. I used the migration utility to go from 2020 to 2021 so I was under the impression that all of my settings would transfer without issue, apparently I was wrong.

Does REGEN or REGENALL command fix your "... text it still has a horrible appearance..."?

For the 'laggy' issue, read this, there are lots of things to try https://knowledge.autodesk.com/support/autocad/troubleshooting/caas/sfdcarticles/sfdcarticles/Graphi...

@pendean No, the regen commands do nothing to improve the appearance.

Had the same exact problem, the file was pointing to ACADE.FMP instead of ACAD.FMP.
