Slow performance with Raspberry PI 3B

[bluszcz]

Hello,

I have recently updated Raspbian on my Pi3B, and I have noticed that libsfml is included in the repositories.

I have managed to compile my project pretty much without any hustle, but then I noticed dramatic decrease of performance - game is not responsive at all, latency events/mouse clicks can be around 0.5s, and it pushed me to measure frames - and I got ~5fps... On laptop the game has few hundres fps, on workstation with Nvidia 1030 2-3k.

And this is not some sophisticated game - pretty simple board game, with main code happening here: https://github.com/deerportal/deerportal/blob/master/src/game.cpp

Does someone have experience with porting sfml projects to Pi and how they work?

Any help/comments appreciated.

Are you using OpenGL ES? The Raspberry Pi only really supports OpenGL ES and if you run OpenGL it will have to emulate the calls in software if it can't translate them to OpenGL ES.

So, I checked and actually it was using default OpenGL - it seems a default libfsfml packages configuration on Raspbian.

I am trying to compile sfml with OpenGL ES, but for now it is crashing:

I found XVisualInfo in several places in system libs:

but nothing in the special Raspberry drivers.

Including X11/Xutil.h results with:

I will keep looking, but any help appreciated.

I managed to compile and install SFML with OpenGL ES, game compiles but crashing on the linking, any tips?:

Okay, after advise on IRC I compiled master version. Performance jumped directly to min 25  fps! I needed only replace Quads with TriangleFan. Thanks.
