BGE standalone player plays animations laggy or stuttering - game itself is 60fps

Game Engine Game Engine Support and Discussion

Hey i tried to make a game on the BGE and when i tried it out in the standalone player or exported it Keyframe and Texture Animations were played in a laggy or stuttering way, but the game itself ran at 60 fps and i could navigate fluidly through the environment.:(:frowning:

This weird thing only showed up in the standalone player when started out of the blender window or an exported executable.
if i started the game in the embedded player in the blender window all ran just fine even if i maxed the size of the window so it was basically fullscreen.

it is nothing related to messed up settings, because just to test i made a completely new file with the default cube animated with an action actuator in the game engine.

Video example:

My computer is a mid 2011 intel i7 macbook pro with an intel HD 3000 integrated Graphics card.

Does anyone know how this happens and how to fix this?
Iā€™d love you for making my work not for nothing

From looking at your video, I think you need to check out these settings:


Youā€™re telling it to use the set animation frame rate of 24 frames per second.
I could be wrong so just try it first.

You should also turn off vsinc as this can reduce your frame rate.

I canā€™t replicate your problem though, have you tried updating to the newest version of Blender?

Iā€™m seeing a few things;
ā€œOutsideā€ processes seem to be a bit high, so exit some background applications. Also, like Smoking_mirror, your animation framerate is low. The framerate youā€™re seeing in the profiler is the physics framerate, under the world tab.

I noticed that in the Viewport the framerate dropped to 45 when playing the game, while the embedded shows 60 all the time. Maybe disabling ā€˜use Framerateā€™ will solve it. (with vsync on)

This let the game run asynchron and is not a good advice. You will loose control over the timing. This means the game will run with different speed on different systems. This can result in a different feeling.

I know. I was just curious if this would fix the problem. Itā€™s peculiar that frame rates differ so much between two players. If by any chance ā€˜use Framerateā€™ is causing this, then you know thereā€™s a problem with it. (I wouldnā€™t be surprised if itā€™s a bug).

Restarting my computer did the thing
maybe there was an odd background process from a dumbly ported game from steam, that caused interferences

I always disable the Use Framerate option since it can cause stuttering and other strange timing issues. You should setup your logic on such a way that it is not framerate dependent.

I guess this was solvedā€¦?

@Moguri - You mean set up motion using a delta time? I thought the physics system is tied to the FPS?

Well, really logic should run, with physics, at a fixed time step :wink:

No friend i think this is good for you got high FPS in all situations.you can manage this level by level of game in same scene i think.
