- In Nsight Systems, is there a way to highlight VSync periods when G-Sync has reduced the frame rate (i.e. increased the spacing between V-Sync clock ticks, to slow up CPU queuing)?
- Does setting Monitor Technology to Fixed Refresh (vs. G-SYNC Compatible) in NVIDIA Settings disable this, ensuring constant VSync periods (constant frame rate)?
In Nsight Systems captures, after a GPU HW Queue overrun, I see where the the driver has increased the spacing between VSync clock ticks for a few frames. But I’m not seeing a way to highlight these regions.
This would be helpful, as these are the regions where app optimization is needed.
For now I’m just disabling G-SYNC to get a fixed VSync rate, and looking for long CPU and GPU frames.
