All the info is really in the video, make sure you watch at 720p.
Performance is virtually the same as the standard particle. At high FPS (800+) the new particles tend to be 3%-5% slower, but are far less susceptible to frame rate drops, and over time end up running faster. BUT .... this level of performance probably won't stand up by the time I have finished all the enhancements.
I was going to wait until I had finished completely to share this but its ended up taking a lot of time, so an WIP update video it is, so I can feel like I have actually accomplished something.
I don’t have many details to give until we can fix that issue I’m afraid. At the moment its a Frankenstein mash of soft and spherical particle techniques, plus some custom blending and blurring, and other junk.
