NoSupportedDevice

I get a NoSupportedDevice error on launch. the game refuses to launch. This computer originally started with an Intel A770 and the appropriate drivers, but the NoSupportedDevice error persists even without drivers, when the device is disabled, and when the device is totally disconnected from the PC altogether.

tried combinations of hardware:

A770 with drivers + 1070 with drivers +AMD integrated graphics

A770 without drivers + 1070 with drivers + AMD integrated graphics

A770 with drivers + 1070 without drivers + AMD integrated graphics

1070 with drivers + AMD integrated graphics

A770 with drivers + AMD integrated graphics

a770 without drivers + AMD integrated graphics

1070 without drivers + AMD integrated graphics

AMD integrated graphics

A770 with drivers + 1070 with drivers + disabled AMD integrated graphics

A770 without drivers + 1070 with drivers + disabled AMD integrated graphics

A770 with drivers + 1070 without drivers + disabled AMD integrated graphics

1070 with drivers + disabled AMD integrated graphics

A770 with drivers + disabled AMD integrated graphics

no change in error. this 1070 was functional with an intel 6700k CPU before this PC was build, still works fine. all drivers were up to date.
