Anyone running an nVidia card is also unable to open PhysiX Control Panel Applet? It reports missing NvCplUI.exe missing. Still, you can access it from the nVidia Control Panel, which for me is the right way to do it, but why the PhysiX icon in the CP then? Drivers v18x and before would work fine, although I didn't find the use of having a direct link to PhysiX in CP just to enable or disable it. Anyway, driver 191.07 didn't work at all for me but now 195.62 is working, only this PhysiX issue. There is a newer version of the PhysiX driver out but haven't downloaded it yet to see if it fixes this.
Also funny, GPUZ reports no OpenCL support for my 8800GT while nVidia states that series 8 and above will support OpenCL with this driver. Direct Compute is also unmarked but that is because support is only for Win 7, maybe OpenCL also?
There is also LAN driver v14.8 out at Intel.
