Anyone played around with the launch config stuff for the TSIV version? I'm finding that 4x80 is far from optimal on certain systems. 6x60 gave me about a 25% boost on a GTX 770 and GTX 780, which on a GTX 860M 4x40 basically tripled my performance (from 50 H/s to 170 H/s). It would be great to hear what others are seeing with the -l parameter.

-l 4x120 gives me 420-450 h/s on my 780 Ti on today's release from tsiv. Lots of posters from the earlier release found good results with -l 8x60 on 750 Tis, but my GPU lost performance or crashed for the same threads x blocks with any number of threads that isn't 4 (i.e. my GPU didn't like -l 8x60 or -l 6x80, and got worse results, or crashed, on these launch configs).

I'm assuming you are on windows. Sounds just like what I experienced when I was running it on windows, I'm running the same card. In order to fix the crashing you can apply the tdr delay reg workaround at the link below. After I did that I was able to run at 6x120 which I found to be the best for the 780 ti. That should give you an additional gain. Let me know if you try it.

Thanks for the suggestion - up to 450-475 h/s range!
