I have a 2008 mac pro 3,1, 16gig of ram, various ssd drives and several video cards to choose from including pc Geforce GT 640 and Geforce GTX 770. Everything works perfectly in El Capitan, Sierra, High Sierra and even Catalina thx to doddude1's installers. The fans/heatsinks are all recently cleaned so it's not thermal throttling.
Boot camp only succeded in trashing the drive so I started from scratch with just the dvdrom, 120gig ssd and Geforce GT120 (from a mac pro 4,1)
With only a blank ssd connected it booted from the dvd and installed win10pro 1803.
Here's the issue, right click for task manager or display settings menus may take 30 seconds to respond. The initial boot screen takes 2-3 mins. Double clicking on an app is also slow to load. Actually it seems like it takes a while to notice the click, then loads as it should.
Once the app loads, for example fusion360 or cinebench15, the cpu and graphics benchmarks are just about right. Same behavior with bare windows generic drivers or Nvidia drivers installed.
If this were a regular pc I'd swear it was a chipset driver issue, but I've installed the drivers downloaded from apple and they didn't help.
I've tried five different video cards which all work fine under High Sierra or in a hackintosh. No apps or updates loading in the background. With/without a swap file, fixed size or system managed...
Anybody know what I'm missing here???
Is win10 just a no-go for the 3,1?
