I tried something different. Since we're upgrading a whole department piece by piece, I went for a completely different build. Equipment: ASUS Prime Z690-P, i9-12900KF, 64GB DDR5-5200, Samsung 980 Pro M.2, Nvidia RTX 3090. Software: Win11x64 Pro, AutoCAD MEP 2022, Fabrication MEP 2022, Navisworks 2022, ReCap 2022. In AutoCAD I am constantly getting the error message "Error Loading Heidi Module - C:\Program Files\Autodesk\AutoCAD 2022\Drv\\acaddm16.hdi".

First off, I wanna call attention to the double \\ before the final name for the file. Is this a simple coding typo that has been crashing my work for the past 4+ months?

Secondly, is this a "first adopter" issue where the hardware I'm pushing is just too new to the scene? I'm not overclocking anything, because honestly, I have no want or need to with these specs. Every single other program I run is AMAZING on these setups. 300 page PDFs open in a second, 20 tabs open in Chrome and it doesn't blink, Navisworks with 30 dwgs and runs smooth, ReCap processes 50 scans in 2 hours... while I'm working.

The only complaint I have is my heart and soul, AutoCAD MEP with Fab MEP for ductwork. When it kills the hardware acceleration, its almost impossible to get anything done. So, I have to close out completely, reset the GeForce Experience to "Optimized", reload CAD, then work for another 30 minutes before... OOPS, hardware acceleration crashed again. Someone, anyone, I'm begging for help here. I will also note the first build I tried this on was an AMD-Quadro setup and it did the EXACT SAME THING! So, don't try to tell me that its just the graphics card being incompatible. This is a true CAD or FabMEP issue.

Attached is a pic of the Heidi error and my Tuner Logs from before and after the acceleration crashes.
