My game targets the standard 16:9 aspect ratio, and the window size is set at 1080x1920 (it's portrait).
Because it's 1080p, it looks super crisp. However, I want to see if I can give it a performance boost by reducing the resolution down to 720p, or 720x1280. It'll look slightly 'softer' on high-res devices, but nothing too horrible.
The problem is that the game is a bit complex, and going through and adjusting every object and event to work with the new resolution will be arduous and prone to error. Is there an easy way to scale the whole game down in a way that reduces the amount of pixels the GPU needs to render?
A dynamic approach is preferable, but any ideas you guys have, no matter how good/bad, will be much appreciated! Thanks.
