Bug ID: 48162 Summary: GPU IRay DAZ Studio returning: NvAPI call NvAPI_GetInterfaceVersionString returned an error Product: Wine Version: 4.18 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: major Priority: P2 Component: -unknown Assignee: wine-bugs@winehq.org Reporter: odhinn@odhinnsrunes.com Distribution: ---
Version 1.40 of DAZ Studio could use an Nvidia GPU to render scenes in the cuda based IRay renderer. Now in version 4.12 of DAZ Studio, it no longer does.
The error in the log is as follows:
