Has anyone on the forum been able to find the "magic settings" to get a Nvidia 1080 to Plot at sustained high speed under windows 10?
All of my efforts have come to failure (starting a 46,000+ nonces... then dwindling down to 2800 nonces). I think I am going to bag it and get an RX 580 and call it a day. Everyone who seems to be happy on this forum with a high speed plotting setup seems to be running an AMD GPU.
Do I have it right? Questions/comments welcome. Maybe I can save someone else the same trouble! :)
I am far from an expert on this, I'm only 3 days old, but the fact you're starting at 46000 and its slowly dwindling down to 2800 means something is really wrong... on a 1050 ti currently I am getting 22500 sustained the whole way through a 1TB file... so please don't spend money on another video card, thats not the problem, so lets try to tackle this without you spending money...
(if I say things you already know or have done, please don't be insulted, just trying to work through it with you to save yourself hundreds of dollars)
are you running the gpu miner in an administrator window? and not just a regular command prompt? when you open it, it should say "Administrator: Command Prompt" at the top of the window, and NOT just "Command Prompt"...
I'm going to assume you're using "gpuplotgenerator" since thats honestly the only gpu plotter I know of, there are probably others so everything I say is based on my experience with that the last few days...
now our video cards are basically the same family, albeit yours is far more fun to have, but lets see if you can copy my settings and get it to work at a sustained speed, or at least a speed that doesn't slowly die off and go down right?

that is my devices.txt bat, not too impressive, very small numbers, and I do that because the larger numbers seem to blow up and crash or cause issues, but start with the basement before you build the roof right?
gpuPlotGenerator generate direct D:\plots\3514366288793510651_36864000_4096000_1024
thats my command line to launch the plotter... now first you can see I am plotting in direct mode rather than buffer, because I want plots optimized right away, and second I have a very good HDD, an Ironwolf that can sustain 100MB/s writes that I am getting with my settings...
now when using my numbers, you MUST change the command line to include YOUR ID number and not use mine, or else the plots won't help you, I'm sure you know which of the numbers this is, for those reading who do not, its the 3514366288793510651 portion you replace with your own ID...
so this will create a 1TB direct plot to the drive... modify the location, modify the ID number, and perhaps modify the size of the plot so you could run a smaller one for testing, although you could just cancel it anytime, and then delete that plot you made in a test folder, remember this is just to test sustained speeds...
it takes me 3 hours to make one of these files, but after 5min my nonces/minute remains steady... so what could be affecting you? a couple things, the most important might be your hard drive itself... open up task manager, and highlight the hard drive you're writing to, to see what kind of write speeds you're getting, it could very well be that your hard drive is the weak link and NOT your video card, I mean you've got an impressive as heck video card, its certainly not the gpu..
so while you're watching the file get created, depending on your hard drive write speeds, that may be your bottleneck and issue, although it is very weird that it slowly trails off in speed, this happened to me once, when I used a non-administrator command prompt, and the second time it happened to me was when I was writing two plots at the same time to squeeze any performance out... so I have stuck with making single plots in direct mode... give it a try!
P.S. like I mentioned earlier, I apologize if you've tried all this or know all this, just trying to save you from spending hundreds on a solution that likely won't solve the problem, buying another gpu, there is a solution, we just have to figure it out...
