Sets the GPU thread priority.
A value that specifies the required GPU thread priority. This value must be between -7 and 7, inclusive, where 0 represents normal priority.
Return S_OK if successful; otherwise, returns E_INVALIDARG if the Priority parameter is invalid.
The values for the Priority parameter function as follows:
- Positive values increase the likelihood that the GPU scheduler will grant GPU execution cycles to the device when rendering.
- Negative values lessen the likelihood that the device will receive GPU execution cycles when devices compete for them.
- The device is guaranteed to receive some GPU execution cycles at all settings.
To use the SetGPUThreadPriority method, you should have a comprehensive understanding of GPU scheduling. You should profile your application to ensure that it behaves as intended. If used inappropriately, the SetGPUThreadPriority method can impede rendering speed and result in a poor user experience.
