Heya Dasaries,
I vaguely remember you asking that question (re: specs of the machines) back in the day, but we’re not directly privy to that information. What I can tell you is that our QA team does it on a large number of different hardware configurations/combinations. We usually grab a few copies of new hardware too. (Our QA folks are always putting in tickets for new and old toys to test on. :D)
As long as your machine meets requirements and you’re running supported hardware, and there isn’t some kind of bug or hardware/software level issue, you shouldn’t see odd behavior from a performance perspective. That’s the point of the troubleshooting after all. We have been monitoring some reports of the 10x0/20x0 series cards (Mainly the RTX) experiencing Rendering Device Lost crashes lately. Currently we suspect it has something to do with NVidia profiling. More on that here. Maybe the work around here gives you some love with the FPS issues? Beyond that you mentioned basically building a whole new rig from scratch, so we’d be back to square one on that.
Let’s take this one thing at a time though. Right now you’ve got something a bit more easily measurable. Once you’ve got a winMTR which captures the issue, definitely post it so we can take a peek. If you can also get a screenshot of your netgraph when the loss is happening, upload it to imgur, and link it to us, we’ll give that a look too.
