You can use the Screen Configuration tool to achieve a similar effect to pixel doubling - just set the resolution of your monitor to something lower.
We would like to get it back in as an option, but don't as yet know if it will be possible to do so.
I saw this in the blog article. The problem is if I set the resolution to half full hd to achieve the same effect, the monitor has to do the upscaling. It's fine, but from what I saw, not all monitors will accept a "non-standard" resolution input.
For now, I guess it is still possible to use the old driver, even with the Pi4. I simply assume it will be removed at some point in the future.
In case someone has an idea... I use pixel doubling to put an app I made with Pygame in fullscreen. The raspberry pi wasn't powerful enough to manage the whole Full HD resolution with an acceptable frame rate, so the app works at half the resolution internally, and pixel doubling makes it full screen without any lag (using the gpu I guess).
I thought of using a "half hd" resolution, but it seems that my monitor with accept it. ( I may have done it wrong, I don't know...)
It is possible to scale it using Pygame, but again, the pi isn't powerful enough.
Pygame2 solves it on some platforms. I can use it to scale the app using the gpu, and it's fast enough. Unfortunately, it doesn't seem that SDL2 uses the gpu on the raspberry pi with raspbian yet... unless the new video driver changes that, but I will need to get a Pi4 to test it first
