NVidia driver 'Threaded Optimization'

Gaming and Visualization Technologies APIs OpenGL

You can enable a feature called ‘Threaded Optimization’ in the NVidia Control Panel on windows (its under 3D settings → Manage 3D settings).

I have noticed that setting this to ‘Auto’ or ‘On’ significantly increases the stuttering in my OpenGL-based application.

  1. I have searched around about information on this feature but I could not find anything besides what seems like guesswork. Is there an official guide/statement somewhere about this feature. For example what kind of OpenGL usage should be avoided?

  2. My first thought was to disable this from my application. Is there a way to programmatically disable this feature from my application. I have read about the “__GL_THREADED_OPTIMIZATIONS” environment variable on Linux. Does this also work on Windows?

  3. If the above is not possible, maybe I could detect the feature is enabled and give my users a warning about this. Is there a way to programmatically detect if the ‘Threaded Optimization’ feature is enabled?

  4. How does the ‘Auto’ mode decide to enable/disable? Is there a way that I could trigger a disable decision from my application?

You can create custom “Application Profile” for your game using NVAPI and disable “Threaded Optimization” setting in it.
