YES HELPS thanks, but I lose the benefit of fast shaded mode, with the models I have in 3d it's very slow
Then you need to find and install different drivers for your video card: newer or older, you'll have to experiment and restart your PC in between these installs.
Show us screenshots of both tabs of your GRAPHICSCONFIG command pop-up please.
In the meantime... instead of turning off GFXDX12... Have you installed the 2025.1.1 Update yet? ABOUT command in your AutoCAD will confirm what you have installed. If not, get it from your Autodesk Account Page here https://manage.autodesk.com/cep/#products-services/updates
Restart your PC afterwards please.
If that did not help... then start GRAPHICSCONFIG command and change the 2D Display Settings pulldown from "advanced mode" to one of the other choices. and uncheck or change one or more of these

Remember, you have a deficient video card / driver, the program can only work around that so much.
Best of luck.
