Fun benchmark :) I'm getting 165 fps (screen refresh rate), 4.5-5.0 in GPU time and 1.0 - 1.2 in CPU time on a 9970x + RTX Pro 6000. Definitely the smoothest graph viewer I've used in a browser with that amount of data, nicely done!

Would be great if you had a button there one can press, and it does a 10-15 second benchmark then print a min/max report, maybe could even include loading/unloading the data in there too, so we get some ranges that are easier to share, and can compare easier between machines :)

165 fps on that setup - that's awesome to hear! Thanks for testing on high-end hardware.

Love the benchmark button idea. A "Run Benchmark" mode that captures: - Load time - GPU time - CPU time - Min/max/avg FPS over 10-15 seconds - Hardware info

Then export a shareable summary or even a URL with encoded results. Would make for great comparison threads.

Adding this to the roadmap - would make a great v0.2 feature. Thanks for the suggestion!

Just to emphasize how good the performance is, I get 34.7 FPS on the Million Points demo... with sampling disabled and fully zoomed out!!!
