Anyone using anything else for GPU mining than XMR-gpu-stak? It's giving just 38 h/s for my Nvidia 860M 4 GB GDDR5 GPU. Though NSCPUminer works fine and gives best hashrate available for my i7 CPU in the same laptop. This laptop is left just for mining only, so nothing else eating away anything...
did you tried this one?
https://bitcointalk.org/index.php?topic=2527462.msg28396744#msg28396744i got 1800+ h/s on my monster testing server, 640h/s for 4cores of NVIDIA TESLA..

Yes, I tried that only, it's giving 38 h/s for this miner only. Do note that I have disabled CPU mining on this particular miner as it was also not giving best hashes for my CPU as well.

something is not OK with your config , i think... delete .txt files from xmr-stak (or better, backup them)... Then start the xmr-stak.exe and answer to all questions once to create again the config file
based on benchmarks, you could have 200+ h/s on your graphic card:
http://monerobenchmarks.info/Tried again by recreating config files, same issue. GPU hash rates not going over 38 h/s, no matter if I disable CPU mining or not via xmr-stak. What could be limiting it?
i think it can be driver, OS, or BIOS, but most probably driver
I tried updating/downgrading to the different Nvidia drivers which were claimed to be stable, but none of them lets it go over 38-39 h/s on GPU. I don't think Bios or OS should affect, as it's not for others as well. Is there some other version of xmr-stak available which I can try?

https://github.com/xmrig/xmrig-nvidia#usage you must choose -a cryptonight
but i think something is with your GPU (for example iu had NVIDIA TESLA and it was splitted to multiple devices/VMs)
Thanks for your help. Tried this release but got this error -

Press any key to continue . . .
easy solution: use less threads in parameter (also be sure you are using --nicehash command switch)
