Re: [AMBER] Problems with RTX2080Ti

We've compiled with 10.0 and 10.1 for RTS-2080Ti and had no such problems.
Not sure about the driver numbers. Can you try this: go into your config.h
and change "-gencode arch=compute_70,code=sm_70" to read _75 rather than
_70. I don't think that's the problem but give it a try.
