Long story short, following a ransom hack into our systems we had to upgrade to Windows 11 and Solidworks 22 SP.5. My desktop was certainly the best built and fastest prior on Windows 10 with Solid '19, SP5, however, it's now the slowest due to specific times. 

The biggest waits tend to be when loading making  a drawing from part or assembly. Not just a few seconds but rather minutes. Once it's able to populate parts dragging the first view takes 10-60 seconds to load the view and then able to populate projected from there without wait. It seems to run faster or closer to normal first thing in the morning typically and slows down over time the more things that get opened or the more traffic across network or some other factor I'm not recognizing. Others are seeing slight slowness but nothing requiring minutes of wait and generally only when saving, or the auto-save interval happens. Others are also on lesser built computers and deal with parts and smaller assemblies generally. None of our parts are generally too complex, basic solid bodies, sheetmetal with some occasional patterns (which are usually expected to be slower). 

In part/assembly modeling, using the orientation menu (spacebar shortcut) is also a locked up wait of extended periods. 

We are running across a network for file saves, templates, etc. and following the ransom attack we had our IT company integrate added security methods to workstations and server, Huntress and Sentinel are the 2 I'm aware of currently being used but there may be something else I'm not familiar with also.

I've been in contact for months with GoEngineer as well as our IT to not much success. 

Machine Specs: Dell Precision 3650, I7-11700K @ 3.60GHz, Micron NVMe drive, 32Gb RAM @3200MHz, Quadro RTX 4000, ethernet connection speeds of greater than 400mbs in both directions generally.  Watching resource monitors nothing appears alarming, CPU is generally 30-50% used with individual cores occasionally around 60-70% momentarily, RAM usually around 40% used, GPU 1-5% and less than 50°C.

I've tried a variety of Nvidia drivers, some better than others, currently running 517.40. List of trials: 573.24, 573.06, 516.94, 553.62, 472.98, 538.95 among others I no longer have saved. 

We've uninstalled Solidworks a couple times, moved all templates locally and saved locally incl. disconnecting from server and internet with lic. checked out, a full windows wipe, user profile rebuild on server. 

Wondering if anyone has any suggestions not listed? Suggested Nvidia driver that is known to function with '22 SP5 and windows 11 on a network license may also be worth a try.

Our next move is a complete format of computer, again (done at time of Ransomware infiltration), and re-installing Windows and programs.
