Another Windows Update release... 186.91 is now available. As with 186.82, HybridSLI is again fully supported. I have not had a chance to run any benches, but if this one is anything like 186.82 it will be a keeper.
Grab it direct from Microsoft:
Win7/Vista 64-bit
Win7/Vista 32-bit
LV2Go has also posted 186.91.
Win7/Vista 32-bit
Win7/Vista 64-bit
NOTE: You will need to run the executable to extract it. Once the driver is extracted, look inside the directory for the 'Additional INFs' .zip archive. Extract this and copy/paste the 'nv_whql.inf' into the top level of the 186.91 directory. Once this is done, run the setup.exe app to install. This is required for the driver to recognize the hardware in the M17x. The default INF (nvfu.inf) does not support the M17x GPUs.
Update: 186.91 was released roughly 10 days after 186.82. 186.91 also offers complete support for the M17x's HybridSLI setup. After a bit of testing, it is my opinion the 186.82 remains the better choice at this time. 186.91 produced slightly lower benchmark numbers compared to 186.82. I also noticed slightly higher temps (idle and load) for the 9400 mGPU. Again, this is just my opinion and I will be staying with 186.82 until the next release. You should conduct your own testing of course. Have fun!
