Benchmark

[epezent]

The demo now includes a new benchmark tool that you can use to gauge how many lines/points you can plot before your frame rate tanks. It can be accessed from the Tools menu bar. The tool ramps from 0 to 500 lines, each 1,000 pts. You can enable/disable anti-aliased lines to see what effect that has on performance.

Here are a few runs I did. The first three are w/o AA, the last three with AA. My laptop specs:

Intel i7 9750H
16 GB RAM
Nvidia RTX 2080 Max-Q

If you have time, please consider posting your PC specs and benchmark results!

2.26 GHz Intel Core 2 Duo (mid 2009)
8 GB RAM
NVIDIA GeForce 9400M 256 MB

OpenGL 3.2, ImDrawIdx == 32 bit, RenderereHasVtxOffset == true

200 lines (1000 pts each), the first three are w/o AA, the last with AA.

Webasm Emscripten version, running on a MacBook Pro (16-inch, 2019), 2,4 GHz 8-Core Intel Core i9, 32 GB 2667 MHz DDR4, Graphics card Intel UHD Graphics 630 1536 MB:

Safari	Firefox

This was benchmarked using the emscripten interactive demo (where I had forcefully set the max fps to 200, instead of the preferrend fps chosen by the browser).

(Note: the online demo will not allow to get fps higher than 50, since it uses the browser preferred fps)
