Well, i bought the card as a upgrade from GTX 480 about a month ago, used 3 versions of nVidia drivers so far and all of them appear to have same weird DirectX issue. 
When i plug the old GTX 480 back, no issues at all. This GTX960 error appears to be binded only with certain titles, DA-Inqisition, Witcher 3, EVE Online and GTA 5 and oldie Command and Conquer Tiberium Wars, any other games works just fine. This message also appears in Cinema4D, vRay Standalone and Unity when i turn on the Global Illumination function when rendering a model. Iam attaching a picture with the error message iam getting. I would apreaciate any info or possible solution.

Core i7 - 3770 3.4GHz

eVGA GTX 960 SSC ACX2 2GB

Looks like a TDR error. The card might have a bad overclock from the factory, unless you are manually overclocking. If you are manually overclocking, I would go back to factory clocks. If you have nay software open that can change clock speeds to the card close it as see if they issue shows up. It may be your power supply as well not giving the card enough power. Make sure all the connectors for power are plugged in on the card. Swap the power supply if you can. If this still is not working, try to under clock the card using after burner or precision x. 

Tried the PSU thing, Fortron 800W swaped for Silverstonetek 1.2kW, no effect, but uninstaled all the bloatware, Precision X included and all seems fine since. Lets hope that problems gone for good.

If you're overclocking the CPU, try setting it back to the stock clocks, and check that your RAM timings are set correctly. Try running a test with 3DMark, or OCscanner to see if the same occurs. Clear out your drivers, either by uninstalling them from the add/remove programs control panel or using DDU, then install the latest version again, but use the "custom" option, and only select the drivers and PhysX in the checkbox window.
