## Link to GitHub Issue or related Pull Request, if one exists n/a ## Description of change In summary: for SDVX VM mode, this PR eliminates the need for `Note FPS Target 120Hz` / `Game FPS Target 120Hz` patches typically used for AMD GPU via synthetic responses provided via a fake NVAPI layer. Before this change, playing on AMD GPU required patches to force the game to render at 60Hz (See #107 for relevant discussion). Basically, if NVAPI query fails, the game shows `I:NvDisplayConfig: GetMainDisplayRefreshRate = 60.000hz (DUMMY)` the game renders at 120Hz but the notes render at 60Hz, which would look stuttery. After this change, even without a real `nvapi64.dll`, spice will provide a stub implementation, just enough to convince the game that the main display is 120Hz, which causes notes to render at 120Hz as well. This can be overridden by `-graphics-force-refresh` option. Important note: if user has the `Note FPS Target 60Hz` patch but running the game at 120Hz, before this change the notes would render at 60Hz, but after this they will be at 120Hz. I don't know why anyone would intentionally lower the notes framerate, so this is not going to be fixed. If the user wants to run the game at 60Hz they can do so via `-graphics-force-refresh`. Another change - `-nonvapi` will always force down this synthetic nvapi path, even if the system has the real `nvapi64.dll`. Even on NVDIA GPU this option can be used to force this. ## Testing
