Feature Request: CPU/GPU execution times for XeSS and XeFG in the public API

[realdody]

XeSS Inspector gets the GPU processing time for XeFG (as shown in the images), but I can't find a clean way to do so in my own project.

It's easy to get XeSS processing time with DX12 timestamps, though that's not so simple for XeFG.

Having a nice public API to query GPU/CPU time from for both would be great. 👍

I'll see what we can do about this.

Are you looking for the total GPU overhead (include proxy -> native back buffer copies) or just the interpolation cost? The difference between the two will be the number reported when XeSS-FG is disabled: interpolation cost is going to be zero, but the total overhead will be higher due to proxy-to-native copies.

Would you also be interested in an API call for querying memory usage?

Having both would be good for profiling. But if it has to be just one, the total GPU overhead is the most useful to me.

And yeah, an API to query memory usage would be great.

Thanks for looking into this!
