I haven't yet looked at performance of grid (circle arc) drawing, will do that. But I just started working on a rather major optimization (that will affect mostly stars and maybe plugins drawing lots of rectangles), will have to finish that first. Atmosphere/ground have very low overhead here so I

Hi! Well, the Atom IS slow, no doubt, but it is usable as travel telescope platform, and its battery life is what made me buy one. I don't know either where to look. Which of the diagnostic numbers in your performance plugin could indicate the problem? Oh, wait - I usually have the azimuthal gr

This is better but still slower that I'd expect; Alex Wolf gets 20FPS on a GeForce 2 (compared to ~10 FPS pre-merge) and I doubt the Atom's GPU is slower. Most likely we have a performance issue specific to that GPU. Unfortunately I can't do much with that without directly working with it. (I have

Hi! I tried again on my Atom (Pineview) netbook. Building in Debug mode is OK, the program has still about 8fps. In Release version, I have about 10fps, and it makes a difference what projection or effects are used or plugins are loaded. (Perspective without atmosphere: 12fps...) At least there a

Stellarium currently uses FBOs through QGL (this has not changed with the refactor). Most likely there's either a bug in QGL or in the driver. (AFAIK Mesa drivers for pre-SandyBridge Intel GPUs are quite buggy). I think we could blacklist (based on http://feedback.wildfiregames.com/report/opengl/

Suggestion from Ferdinand has fixed the rendering: in src/core/renderer/StelQGLViewport.hpp, line 102 (StelQGLViewport constructor), replace fboDisabled(false) with fboDisabled(true) Incidentally glxinfo reports that GL_EXT_framebuffer_object is supported, I guess this is a different feature from
