GPU for nVidia?

[TeaLeaf]

Any sign of an nVidia compatible version of F@H for GPUs?  I know it's meant to have been delayed/shelved due to nVidia's core architecture being crap, but I have a couple of 8800GTX cards sitting in this machine rendering word documents and spreadsheets for most of the day, so wondered if they could be put to more use.

December 2006 We have been looking into the ability to run Folding@home on nVidia G80's and have found a bug in the G80 driver. We have informed nVidia about it and are waiting for them to resolve it.            

March 2007 We are nearing completion of our next major revisions to the GPU core. We hope to have it out in a month or two (but GPU coding has been notoriously complex).

The question has been asked, and answered many times in this thread, and elsewhere.
The problem is that the drivers supplied by nVidia don't work with the GPU client. FAH is waiting on working drivers from nVidia. As you may know, nVidia has been having problems developing drivers due to the MS Vista release.
This is not an issue which can be solved by a FAH client.
 
Historically, the FAH GPU client development was started on an nVidia platform, but persistent problems with data accuracy/integrity seemed to be inherent with nVidia GPUs, so the GPU client was fully developed using the ATI X19XX platform instead.
 
NVidia has touted the potential of their latest processors for GPGPU implementations.  
There is speculation that nVidia has realized that scientific inaccuracies remain in their current chips, and that the FAH GPU client would reveal those flaws (bad news for nVidia), so working drivers have not been forthcoming.
If the design flaw persists in the 88xx chips, then we won't see a working nVidia-FAH GPU until the design bug is fixed in their next generation chips.
 
NVidia is welcome to disprove the speculations... are they listening?

Hm, interesting :g:

Thanks BB, that's the news I was referring to in my last post, just wondered if there was any change.

Going over some Danish IT articles, rumour has it that the 8800 can be made to work with the f@h software as it is, however not at maximum performance. I have not been able to find more about this though.
