Hello! I am working on a Falling Sand + Artillery game. <a name="p-160148-tldr-why-is-stretching-images-over-a-higher-resolution-significantly-more-expensive-even-if-the-original-image-res-stays-the-same-is-there-a-smart-way-to-render-something-on-multiple-layers-and-then-upscale-that-without-loss-or-blur-2" class="anchor" href="#p-160148-tldr-why-is-stretching-images-over-a-higher-resolution-significantly-more-expensive-even-if-the-original-image-res-stays-the-same-is-there-a-smart-way-to-render-something-on-multiple-layers-and-then-upscale-that-without-loss-or-blur-2" aria-label="Heading link"> TL;DR: Why is stretching images over a higher resolution significantly more expensive, even if the original image res stays the same? Is there a smart way to render something on multiple layers and then upscale that without loss or blur? To kee…

Does the grid size of your sand simulation adapt to the resolution?

Yeah, but once again, just the internal resolution, not the output resolution. The sand grid is defined like this: int[] sandGrid = new int[MAP_WIDTH * VSCREEN_GAME_HEIGHT]; …with MAP_WIDTH being the internal horizontal res multiplied by the factor of how big you want the map to be. But this grid…

Would you mind creating a minimal sketch that reproduces and isolates the performance issue you’re seeing? That would help diagnose the issue, and figure out whether that’s something maintainers need to look into.

Hello @Braunstein , I was inspired by your topic and shared code in the Gallery: Processing PGraphics Image Scaling and Renderer Test Tatooine came to mind and I found the image (classic scene) I was remembering: [image] Scientists discover 3 Earth-size exoplanets that may have double su…

Hello! @glv That’s a really cool sample sketch you made. I’m too young to have watched the original trilogy in theatres, unfortunately :^) But I’m glad my little screenshot inspired you! As for the problem- I didn’t know P2D uses the GPU instead! It is indeed much faster now. Though, a different p…

[image] Braunstein: The performance P2D gets is amazing, but ideally, I’d like to have the best of both worlds- the untreated image of JAVA2D and the performance of P2D. I experienced the same problem when I was creating the G4P (first released in 2009). In G4P text drawn using the P2D / P3D …
