Please try to use --gpu-platform directive to resolve the igpu/discreet gpu issue in sgminer
Benchmark doesn't really give much details about error feedback, to see those, you need to mine directly to a working pool and right click on miner -> diagnostics, there you can see more detailed error captured in the output dialogue window
How would I go about doing that? I tried adding it to the user defined command line option in the Managed Software section, but it only flashes and will not load when running a benchmark using sgminer.
umm, you can add that to the profit profile specifically for sgminer (and forks)
also, you need to specify the correct number, 0, 1 or 2 for the --gpu-platform, it's rig specific.
check sgminer --help for details.
***
worst come to worst, just use command line and mine to someone else's address using examples for starters, there you should see all the error messages in the console. of course, if you are familiar with command line, then just replace the command, addresses as you see fit. Else, consider it a tiny donation.
