Does anyone know if this will help Octane Users at all?

Or cause issues ;)

New in GeForce 310.90:
Adds a security update for the NVIDIA Display Driver service (nvvsvc.exe).
Improves performance for GeForce GTX 690:
Up to 19% faster performance in Autodesk 3ds Max when interacting with large models compared to GeForce GTX 480.
Up to 60% faster performance in ray tracing applications such as NVIDIA iray and Chaos V-Ray (subject to the scene fitting into graphics memory) compared to GeForce GTX 480.
Up to 76% faster performance in the 3D extruded ray tracing capability in Adobe After Effects compared to GeForce GTX 480.

NVIDIA CUDA
Includes support for applications built using CUDA 5 or earlier version of the CUDA Toolkit. More information at http://developer.nvidia.com/cuda-toolkit

I've updated to the 310 drivers, and saw no performance increase with any of my GPU's. Sorry.
I'm sure there is unlocked resources and potential in the new drivers, and the Octane team is probably on top of it!

Many Thanks
I see you are running a mix of cardmodels... myself also... You did not have any issues after the upgrade with certain cards not being seen did you?

No problem, and nope, It recognizes the cards just fine.
I have however seen 2 blue screen of deaths (BSOD) in 2 days. Although that might just be coincidence.??

New drivers usually have only a marginal effect on Octane, since we don't use most of the driver features and the driver overhead is fairly small. (We are actively trying to minimize driver calls)

We see one major improvement of 310.90 over all previous driver versions: To see how far you can go, we built a render machine with 4 GTX 690, i.e. 8 GPUs. Turned out that having more than 5 NVIDIA GPUs is causing massive headaches, especially with CUDA memory allocation/de-allocations. Fortunately these issues are gone with 310.90.

OpenGL is still not working using an NVIDIA card as display card, if you have more than 5 NVIDIA GPUs in your system, but using the on-board Intel GPU works around this problem.

-> If you have a big system with more than 5 GPUs, you should try this driver.

Cheers,
Marcus

I have 3 GTX 690s. I have been having crashes in the Maya plugin with all 6 GPUs enabled. But much less frequently with the new drivers. I have been using the onboard Intel GPU, but it will crash occasionally too (with a "recovered from error") Windows message.
