Don't use Nvidia 331.40 beta drivers unless you have a 780 (or possibly Titan)

Based on reports from EVGA and OCN, it appears that the latest beta drivers, 331.40, really tank people's PPD unless they have a 780, e.g. going from 96k to 35k PPD on a 770. For me, at least, they improved my 780's PPD over 327.23, which had gotten rid of the 36-hour crash but which was noticeably slower than 320.49. These are a bit slower than 320.49, but only by a couple seconds per frame, which I consider to be a reasonable tradeoff for not having to reboot every day.

I haven't seen any reports regarding a Titan. I would think that since they're both GK110 that it wouldn't be adversely affected, but that's just a guess.
 
Damn you cruel driver world! Ever since the first drivers supporting the GTX 700 Series, every driver after that has slowly dipped the PPD til now I"m at 10K less PPD. It was about time a driver came along to fix that, but not if it screws up my other 600 series card.


*sigh*


Thanks for the warning. Hopefully the final resolves that issue.
 
I don't know how they do on anything other than a 780, but before these came out I was running 327.24, which were developer beta drivers. They were stable and faster than 327.23 and 326.80, albeit slower than 320.49. As a point of comparison, on my 780 project 8900 had a TPF of 2:51 on 320.49, 3:10 on 327.23, and 3:01 on 327.24.
