I have found similar results with -m 2611 and -m 2711 (the only ones I tested). With single hashes or when using benchmarks v3.00 far outperforms v2.01 but as soon as you have a sizeable hash list with a straight wordlist it can no longer keep up. It seems to be slower at transferring data to the GPU, because by using rules I was able to get excellent performance again. I will be keeping v2.01 for straight wordlist cracking and v3.00 for rules for now.
This may have something to do with switching over to OpenCL from CUDA for Nvidia, but this goes way over my head so I am just guessing here. But if someone with an AMD card would like to test and see if the same holds true for them, that would be nice. :)
Note: I hoped it had something to do with the new workload profiles so I tried setting -n -u and --opencl-vector-width manually, specifically optimizing it by trying until I found the best result for my list and setup. It still could not keep up although I did get closer: ~740 MH/s vs ~900 MH/s with -m 2711. I have a GTX 970, just for the record.
Edit: I totally missed the part where you already used rules! Try tuning manually, and see if that helps: https://hashcat.net/forum/thread-5184.html
Edit2: I use NVidia driver version 368.39
Update: After more testing it seems that rules alone are not quicker either, it is really bruteforce and hybrid modes that are quicker. I will be sticking with v2.01 for most things, but will definitely perform hybrid and bruteforce attacks with v3.00 because the speed improvement is over 100% in some cases.
