Running NiceHash on my CPUs will get me about 2 sols/s, but using the nvidia card is getting me 0 Sols/s while it shows 982 I/s. Anyone know what causes this?
I’m using Nvidia drivers 21.21.13.7570 on Win 10 64-bit on a GT 730
Yes, I’m experiencing a similar thing with my GeForce GTX 560 Ti.

@nicehashdev, this didn’t occur prior to v0.3a of nheqminer. Any thoughts?
I found another thread with another cuda issue with a link to this archive : CUDADll's
This solved the problem for me.
I have not tried to get back tho version 0.2 of the miner, or used the dll bundled with it.
By the way I got this problem on two mobile gpu : 860m & 960m on windows 10 64bits.
Did your I/s drop dramatically when you switched out the DLLs? Mine was at 900+I/s and now it’s 0.68 I/s. However it is working now at 1.39 Sols/s whereas it had 0 before.
The guy on the other thread also recommended downloading the latest CUDA, which I am still working on as it’s a 1.2 GB file and going slow. Maybe that will help.
