Perf HUD values available via ovr_GetInt?

Is there a way to get the values displayed in the Perf HUD programmatically through the API, perhaps through ovr_GetInt? Specifically, the "Unused performance" value could be very useful in dynamic performance scaling.

    Hello,

    I am very interested in this as well. How can we access the values displayed in PerfHUD?

    Sadly, these values are not available via the API. It has been requested before, and it's something we are exploring.

    For now, you can try using GPUView. See this talk: https://www.youtube.com/watch?v=NaQ8RJKe3cE

    Hi Cyber, thanks for the response.

    What I was hoping to achieve with this feature is something near optimal performance tuning, done dynamically and automatically. Right now, I can turn on the HUD and manually dial in my render target size until the unused percentage nears 0%. This way, I think I can squeeze out all the resolution my rig can muster without dropping frames.

    GPUView is great as a development tool, but requires instrumentation and can only offer insight into the app offline. The perf HUD already distills all the salient info about performance into one intuitive, easy-to-use heuristic. If we could just access it on a per-frame basis, we could really max out our users' GPUs. That's good for business, right? :D
