Forward+ Rendering is a technical term that is extremely important in rendering and optimizing game graphics (technical art). A drawing method that achieves both translucent drawing and a large amount of light placement by dividing the screen into tiles and applying only the light related to each tile to pixels.
An example in the real world: ``Batch sorting and delivery by area (by neighborhood association)'' by a postman.
When delivering mail (light), conventionally (forward), each time there is a letter, the mailman goes to the house (object) on a motorcycle to deliver it. With Forward+, mail is sorted by neighborhood association (tile) in advance, and the bike that delivers it to the neighborhood association packs only the letters belonging to that area into bags and distributes them all at once, dramatically reducing the effort required for delivery (drawing passes).

Detailed mechanism and operating principle
Forward+ (Forward+) is enabled, the entire camera screen is divided into tiles into a grid, the lights existing in each tile are listed in advance, and lighting, including translucency, is calculated efficiently.
