I expect having multiple people file bugs might not be a bad thing, it shows there is a spread of developers requiring that it works, rather than just a lone voice.
Its likely only Producer really tries to set up frame control properly, the games might not even know about such things. Dropping a frame on a games is much less critical than it is on a simulator.
As for putting in a fix into Producer because NVidia don't have a reasonable update rate of the drivers is really pushing the problem onto the wrong set of people, just because we a more friendly and approachable. Push NVidia on it, there drivers are generally very good, but still not good enough - you arn't able to use their SLI hardware you bought because their drivers arn't good enough yet.
Well you always have the source code, so you you have hack together a local workaround.
I will try to report this to them. How do you submit bug reports to
Nvidia, btw? By sending mail to [EMAIL PROTECTED]?

I understand this quite well, however please keep in mind that this bug:
1) Is in the drivers at least since March 06 or so when I first tested
OSG with my (then) new SLI system.
2) Nvidia releases new Linux drivers every 6 months only and the next
release will be probably in February '07 or so (8774 was released in
August). There may or may not be a new driver this months, but that's
just speculation.
3) Only OSG/Producer seem to be affected - everything else seems to be
working fine for me, even games in Linux. Strictly speaking, it is most
likely Nvidia's bug however if only OSG has a problem with SLI systems I
am not sure how much they will be willing to address it. SLI on Linux
doesn't seem to be their highest priority - not everything is supported
yet and the stability is not the best neither.

However, I will defer this decision to Don and you. I just want to be
able to use OSG on the machine I bought for that purpose.

No, that is not what I meant - I do not want to override the install
directory, I would like make install (or installdbg) to install also the
debug version of the libs. This doesn't seem to be possible at the moment.
I'm not sure what you are after. The build system is pretty flexbile, perhaps Don can point in the right directly on his return.
