I have been running AutoCAD MEP 2022 since its release, and I also use Fabrication MEP 2022 for my ductwork. My aging machine had a GeForce TITAN Black video card, and I never had an issue. Last month I was able to get my hands on a Quadro RTX 4000 build for a reasonable price, so I jumped on it. Well, it has not been great. I frequently use pointcloud files - generated from ReCap, and also Navisworks. My entire workflow is Autodesk, I am not mixing brands of software. I keep my Quadro Driver on the Autodesk certified driver version (as of writing 452.57). But, no matter what I do, my Heidi module crashes, I lose Hardware Acceleration, and I ask myself, why the hell did I even upgrade? Once the Heidi module goes, its about 50/50 if my CAD file will crash as well. I thought the Quadro certification process would make this rock solid, instead its been all nightmares. I've tried testing with and without pointclouds on, different visual styles displayed, different Fabrication databases... always the same thing. Any advice would be appreciated. And for the record, the computer had a fresh install of Windows when I started last month, then all of the updates were installed, the Autodesk products were all fresh installed and updated, graphics driver is dialed in... Revit, ReCap, and Navisworks give me no problems (they run great), only AutoCAD.
