不知道ppd如何。。。提升了还是有要下降。。。

A卡的飘过,PS:9.3感觉CPU占用没优势。。还和9.2差不多。准备换N卡.

这个驱动有问题。貌似N卡又搞老一套,用精度换速度(这里指游戏速度)。
为了这个斯坦福官方还专门升级1.25版core,用速度(这里指计算速度,即ppd)换精度,造成1.25版core ppd大幅下降(~10%)的问题,害得斯坦福官方为N卡背黑锅,被埋怨惨了。
BS N卡官方的无耻行为,顺便问候N卡驱动程序员全家族女性成员。

顺带提一下,电流毛刺也貌似与此也有关,N卡内核计算一会儿,就要停下来,做精度修正(以免误差越来越大)。然后再继续算。
不过这只是我个人的猜测,未得到官方证实。有心人可以到官方想办法证实一下。

FAH 运算和精度有关系么???

不懂,来解释一下...

而且哪里有证明说是NV的驱动画质下降了....

What I said above is true (except I put down the wrong driver version) but there's more to the story. Let me add some details so it all makes sense.

Within the last few days (well, I guess it really may have been a week or so), a problem was noted with 185 drivers getting high PPD because the work was not being completed. This bug needed an urgent fix.

Independent of that, improvements were made to the science code had been made to an unreleased version of the FahCore (improved accuracy but more computations required). Both changes were made simultaneously in v1.25.

Benchmark values do depend on what code is being run and it's not possible to rebenchmark everything immediately after every change. Those WUs which were benchmarked with the less accurate science code will see a loss in PPD until they're benchmarked with the more accurate science code. Once that happens, some order will be restored.

I can't comment on the magnitude of the data you're reporting since I haven't verified the numbers myself. We'll need a response from the Pande Group as to what happens next.

再来官方技术人员的。

There was a bug in the core that interacted with some changed behavior in the 185.20 driver. The good news is that it doesn't appear that this particular error "contaminated" any runs; the effect here was that some results were simply not calculated (and therefore not returned), not that returned results were corrupt. Core execution was faster precisely because not all the calculations were done.

I've released an updated version (1.25) of the core that appears to fix the bug; your clients should automatically update when they get a new 59xx WU assigned, or you can manually force an update by stopping the client, deleting FahCore_14.exe, and restarting. Please reply to this thread if you still see the PPD "doubling" with the 1.25 core, as the core results are definitely missing some returned data under those conditions.

Thanks to mikeb12, Turnoz, and the F@h beta testers for helping me to unravel this issue.

貌似FAH是依照CUDA来吧 很游戏驱动貌似无关~~ 电流问题真的是因为需要纠正精度?
希望小月也来讨论一下~

177.92照样毛刺...难道N家驱动全坏了?电流毛刺还是590X的问题~STU想推卸责任是不可能的
