This rollout roll-out is accessible when Mode is set to Points. When rendering in Point mode, changing the Image Output resolution from the Render Settings will affect the appearance of the particles rendered as points. This is due to the fact that points are treated as pixel-sized. If you double the resolution, make sure to double the Point Alpha and Point Radius settings as well.

 

Ignore Particle Size | ignoresize – By default, the point shader calculates the alpha by considering the size of the particle and the distance to it. This option is used when the particle system contains particles that are too large and leave hard tracks with motion blur.

...

Motion Blur Limit | mblimit – If the particle system contains very fast particles, or if the motion blur step is too small, there is a possibility of rendering overload due to a huge count of particle copies. This parameter sets a limit on the number of clones to keep a reasonable rendering time.

ptSizeExtra – Script parameter that is 0 by default and can be increased to suppress grid artifacts. Increasing the value too much might slow down the rendering considerably.

The diagram below shows the render differences between two images rendered at 960x540 vs 1920x1080. The 1080p image is scaled down to 540p to show the difference in the apparent Point Alpha and Point Radius.
