And in an extended troubleshooting effort, I deleted all the stuff that really lands in complex vector, leaving essentially linework. There are 3D data, but everything I'm trying to render 99.9% of the time is 2D as far as the screen is concerned. Most of the drafting that I do is really 2D, mostly simple vector (linework and hatching), a little complex vector (solid-shaded hatching). I'm not thrilled with my memory or disk benchmarks, but they're in the 60s for percentile, which suggests they're not the weak link.

2D graphics, on the other hand, is 462 or 34th percentile. 3D graphics, I'm at 7369 or 86th percentile. The most surprising result was fairly low benchmark score on 2D graphics with this card. I ran a benchmarking test on my machine, and found some interested results. 2x 6-core Xeon E5-2640 CPUs, 64 GB RAM, SSD, P4000 GPU, Windows 10 Pro 64-bit, very latest drivers and BIOS, etc. I had a custom computer built around the Quadro P4000 card. I decided to buy/build a new machine myself.

I upgraded to C3D 2019, and had slightly worse (than my already crappy) performance, and it was affecting my work substantially. More than enough per Autodesk's hardware specifications (the rest of the system, too). I had been using AutoCAD C3D 2014 for a while with relatively poor performance - slow and choppy panning and zooming with 2D drafting, often locking up and crashing on anything more serious - on a Dell M4800 with a Quadro K1100M card. I'm happy to see benchmark tests for other cards and hardware configurations, but I'm specifically looking for a 1:1 comparison of the nVidia Quadro P4000, since that's my card. If you've got something else (that's free), feel free to run it on your software and just let me know which you used so I can grab it myself. It will assess and stress-test CPU, memory, drive(s), 2D and 3D graphics. If you're willing to run a similar test, I'd really love to see the comparison. I used the free trial period of PassMark PerformanceTest to benchmark my machine.

Run a benchmark test on your system, or at least the graphics card, and report the results to me, please. If you're using an nVidia Quadro P4000 GPU, specifically, I'd like to ask you a huge favor.
