Debugging multi-pass support at the moment, exposed an option to write the HLSL to disk with spirv-cross. We normally go straight from SPIR-V to DXIL for the cross compilation but it can be helpful to look at the intermediate HLSL to sort out some issues.

There's something about that graph that I really like. I'm going to borrow that :D

Implot is great! Here the smoothed result is a 60 frame moving average. I have no frame-in-flight mechanism yet though. Need to set that up and add time stamp queries for true present-to-present times.

Let me see if I can cook something up before collapsing from tiredness. I've typically just looked at an exponentially moving average of timer queries, but I'm pretty tired of being at the mercy of whatever noise phenomenon might get in my way to get something sensible and reliable from it.

Lately I've actually become more partial to actually "just looking at the time series", but on demand in a separate project. But I realize I can actually just display a graph like this in a tooltip on hover

How specifically do you decide on the upper and lower display range?

parsaie.bsky.social•157 days ago

Right now, ymin=50% of the moving average, ymax=150% the moving average.
