twitchy graphics

[JazHaz]

Now that development of GB has been taken over by Razer ("High-performance gaming hardware, software and systems. For Gamers. By Gamers.") I would expect it to get even better, although I haven't tried a Razer version myself yet.. something I must do, now I have a Win7-64bit install again..

I use the current Razer GB version. It's good, but I feel that the performance increase isn't as good as with the Iobit versions.

Does Oolite impose some kind of V-sync of its own?
If that's the case, I'm leaning towards the conclusion that the culprit lies there.

Yes it does (at least on Windows and Linux), provided that your drivers implement the WGL_EXT_swap_control extension. But I doubt that this would be the root cause of the problem. On my laptop I do not have this extension but I still get the occasional stutter.

Any way to turn that off, I'd like to test my 'theory'?

And I still think that those occasional stutters are a whole different matter than the un-smoothness of the graphics engine.

I hope this isn't muddying the water here, but going back to the buoy video again two things struck me.
Firstly that the rotating object (in this case at least - I haven't yet checked any others) is always in the same part of the rotation when this occurs. That is the same rotational position and orientation.
Secondly (perhaps based on the rate of rotation?) it occurs regularly - every five seconds on the buoy video.

Same observation with a rotating Coriolis here: turn - turn - twitch - turn - turn - turn - turn - turn - turn - turn - twitch - turn - turn - turn - turn - turn (that sequence representing 2 complete revolutions)

You must rebuild from source. Go to src/SDL/MyOpenGLView.m, find the -init method and locate this block of code around line 217:

Code: Select all

   SDL_GL_SetAttribute(SDL_GL_RED_SIZE, 8);
	SDL_GL_SetAttribute(SDL_GL_GREEN_SIZE, 8);
	SDL_GL_SetAttribute(SDL_GL_BLUE_SIZE, 8);
	SDL_GL_SetAttribute(SDL_GL_DEPTH_SIZE, 32);
	SDL_GL_SetAttribute(SDL_GL_DOUBLEBUFFER, 1);
	SDL_GL_SetAttribute(SDL_GL_SWAP_CONTROL, 1);	// V-sync on by default.

Remove that last line and rebuild the game.

[Zieman]

Removing those lines (I also removed the SDL_GL_SetAttribute(SDL_GL_DOUBLEBUFFER, 1); line) has no effect. Oolite (this time 1.79) just fluctuates between 56 and 63 FPS, and graphics are jittery, even with constant entity count & memory usage.
I've tried with V-sync on application setting, V-sync forced on & V-sync forced off. No difference whatsoever with Oolite. Other games do recognize the V-sync setting.

You talking about the GPU's V-sync, yes? With V-sync on, I get 75fps (my monitor's native res) - with V-sync off, I get 99fps (but the 'tearing' is pretty bad).



Or am I off-track?

[cim]

For me, with SDL_GL_SetAttribute(SDL_GL_SWAP_CONTROL, 1) commented out and vsync turned off in graphics card settings, I get ... well, very variable. Between 60 and 99 FPS, depending on what I'm looking at. With either on, I get 60FPS, with a bit of variation. A little bit of jumpiness is to be expected here, because the FPS counting takes place as part of the Player update in the main thread, so even at a solid 60FPS overall, the time between FPS checks is not going to be an exact 1/60 second every single time.

I wouldn't advise commenting out DOUBLEBUFFER: that's very unlikely to help.

Have you tried the logcontrol test yet? vsync seems rather unlikely to me as the cause - if the average frame rate is ~60FPS, then even if it ran very slightly over and had to wait for the vsync, that frame would still only take 1/60 second longer to render, which shouldn't be particularly noticeable. And on a high-end system, it should be completing most frames in plenty of times unless you have a ridiculous OXP load and/or are running at too high a resolution for your GPU.

GPU V-sync, yes.
I was expecting 100+ or 200+ FPS with V-sync off, but no, only that same fluctuation between 56 and 63 fps: 59-60-63-59-56-63-59-60-59-56-60-63-56-60-63-56-59-63-60-56-59-etc.etc.
The fluctuation dampens when I start recording a video, then it is only 59-59-60-59-60-60-59-60-60-59-60-59-60-60-59-59-60-59-60-59-59-60-60-60-59-60-etc.etc., until I stop the recording - about 5-10 second after I've stopped recording, that infuriating 56-63 FPS fluctuation (and jitters) start again.

[cim]

You'll never get more than 100FPS at the moment. For now, the draw code and the update code run in the same loop, and the loop doesn't run more than once every 0.01 seconds. So that's the maximum no matter how fast your computer (and there's not really any point in running faster than that)

Here's some timing results for me. Normal first - completes in ~0.13ms and then waits for the vsync - then three anomalous ones with a visible stutter.
