The solution, above, is forcing the drm device to be always "on", disabling automatic "runtime suspend" before it freezes (so at boot).

What are the side effects of this disabling runtime suspend? Temperature, CPU?

Re: Fast(er) image rendering to screen on a Pi3

For reference if anyone is reading, I've tried another version

https://github.com/audetto/TwinklebearD ... in.cpp#L68

using SDL_BlitSurface + SDL_UpdateWindowSurface but it generates massive rendering artefacts.
On the other hand, it looks like it is faster.

Fast(er) image rendering to screen on a Pi3

I am working on a computer emulator and I have the need to display a bitmap to the screen fast (60FPS?) I have tried using Qt and I get about 30 FPS at the cost of massive CPU usage.

Re: Still using Minecraft?

This is definitely true and Minecraft resonates a lot more than Minetest or some other "piworld". In the same way that people on a pi are encouraged to use LibreOffice (hoe many users does MSOffice have?) some effort towards fully open 3d worlds would be welcome. Having said that, I struggled to fin...

Still using Minecraft?

I still see a lot of articles and examples about python scripts for Minecraft Pi. Why do I say "still"? Minecraft Pi is a dead project, never to be updated again. Only runs on the Pi. Its integration in the destkop is less that optimal with odd mouse behaviour. There are pretty good FOSS alternative...
