pIRender for Windows does not use hardware acceleration at this time, so it will be much slower. Sometimes MUCH MUCH MUCH slower.
Try increasing the stage width to 1808 pixels. I’d also suggest creating a simple project (very simple point emitter zoomed up so you can see it — something that doesn’t create a ton of particles) for testing. Use the same stage size, but simplify the emitter so it doesn’t take minutes to render each frame.
pIRender for Windows has problems with some widths, but I’m not sure exactly what the problem is. Here’s how I deal with it when I have “scrambled” results. First, find out if the width is evenly divisible by 4. If it’s not, increase it so it is. As an example, say I have a width that’s 790. 790 / 4 = 197.5. To increase it, round up and multiply by 4: 198 x 4 = 792. If that width does not work, then check to see if it’s evenly divisible by 8, then 16. Round up and multiply each time. Make sense?
