465 | * Normally all GPU commands are processed before rendering the | |

467 | * -- it forces the game to render as if it was 60fps and leaves the | |
468 | * GPU idle half the time on a 30fps game, for example. | |
469 | * | |
470 | * Allowing the renderer to wait until a frame is done before | |
471 | * rendering it would give it double, triple, or quadruple the amount | |
472 | * of time to finish before we have to wait for it. | |
473 | * | |
474 | * We can use a heuristic to figure out when to force a render. | |
475 | * | |
476 | * - If a frame isn't done when we're asked to render, wait for it and | |
477 | * put future GPU commands in a separate buffer (for the next frame) | |
478 | * | |
479 | * - If the frame is done, and had no future GPU commands, render it. | |
480 | * | |
481 | * - If we do have future GPU commands, it meant the frame took too | |
482 | * long to render and there's another frame waiting. Stop until the | |
483 | * first frame finishes, render it, and start processing the next | |
484 | * one. | |
485 | * | |
486 | * This may possibly add a frame or two of latency that shouldn't be | |
487 | * different than the real device. It may skip rendering a frame | |
488 | * entirely if a VRAM transfer happens while a frame is waiting, or in | |
489 | * games that natively run at 60fps if frames are coming in too | |
490 | * quickly to process. Depending on how the game treats "60fps," this | |
491 | * may not be noticeable. | |
