My application is showing cyclic framerate drop for no reason( rendering the same point of view, simple static scene).
I decided to use nsight to see what’s happening but unfortunately, when nsight graphic debugger is attached, the framerate becomes stable.
Here are some (tiny) screenshots of the frame times over time.
Thank you for your answer.
I’ve finally found the cause, and forget to write the solution here.
The problem was that I had a few very large textures that I used to generate smaller SDF during loading, but never released them. As a result the GPU memory was saturated.
