v3.4.18 SLI major issue

[vgbaron]

Beau - tried the cfg edit you posted. Had no effect. NONE of the drivers work in SLI now.

Same here with SLI Titan X (Pascal) latest driver, in Non SLI no stutters at all.

A new nvidia driver with some SLI correction is available. 376.48

But I can't test it. I'm not at home.

Thanks, but this is a P3D problem not of Nvidia and in the new driver p3D is not even mentioned.

While I still maintain that this is not a driver issue I gave 376.48 a go and no change - SLI still broken.

I hadn't said in my OP that another symptom is hanging at 100% loading stage on some app starts but not all.

There seems to be some confusion (both in these forums and at avsim) over this latest 3.4.18 issue and it is getting incorrectly associated with the existing known SLI issue which DOES appear to be driver related (as using older driver solves it). With this NEW issue it does not matter what driver you use AND the symptoms are more severe (i.e. it renders the sim in SLI as UNUSEABLE!) and includes, but is not limited to, single digit fps, flashing red info text (corner text), flashing menus and so on. The EXISTING issue appeared to be limited to effects such as contrails, smoke, etc.

It would be good for LM to at least acknowledge this new issue - as it stands our choice is to no longer update Prepar3d or not use an expensive second graphics which I (and probably many others) bought especially for Prepar3d. Of course given the time of year and the fact that we can still use 3.4.14 this urgency is reduced so Happy Holidays LM Prepar3d Team and here's to a solution in 2017 (early!).

376.48 doesn't fix it. We can roll back to the previous hotfix?

[vgbaron]

@thundercat - you can roll back *IF* you kept a copy of the prior version.

@boaz - my symptoms exactly including the occasional hand at 100%.

@Beau - yes, there has been and still is an issue with the driver and SLI but prior to this update we could at least roll back to an earlier driver and use SLI. This update has effectively killed SLI.

Done all the suggested actions, no luck, reverted back to 3.4.14. 2 GTX 780 msi here.

All,

We are investigating. Thanks for the reports.

That's all we can ask Adam.

Thanx and a Merry Christmas to all the P3D team!

I have exactly the same trouble. Is it possible to download and reinstall the hotfix 1 client.msi?
