How to handle the jitters? (or at least make it bearable)

[AwesomeCool]

Hi everyone.

I noticed that the more stuff I add to a map, the more jittery it become (no matter the resolution). It is literally becoming nearly impossible to play test the game now due to the jitters.

If you do not know what jitter is, it is when the player is moving and the map looks like it is shaking.

I was wondering if anybody found a good fix for this yet (or is planned to be fixed).  If not, is there a way that was discovered to at least lower the frequency of the jitters.

I have zero scripts installed, before anybody asks about that.

It happens no matter the size of the maps and it gets stronger the more stuff that is added to the map.

I am starting to get desperate....

please help!

It should be automatically created as bugfix scripts when you created a new project. Or at least, in my RPG Maker

Find a script made by @Source. Or just ask him.

It is not for free... but it works gracefully really. (seen it on a game before and after adding it by the creator)

It is the player character( not events) moving that causes it

If it is effectus, I already have it (and it isn't helping).

edit: effectus is helping just not with the jitters

I think I found the solution.

If you use MGC tilemap rewrite the jitter dissapears

As the player character moves, the screen has to be redrawn. This includes redrawing the events and the background.

I installed that event jitter fix and it didn't help.

MGC tilemap rewrite seems to help a lot (but not completely get rid of it).

Could we get a demo or video posted to see what exactly is happening?   Also, have you tried copying your maps and everything over to a new project and seeing if the problem persists?

You need to find the cause for the jitter before you can fix it. For example there is one case of jittering that only happens when the player speed is set to the slowest options due to a rounding bug, and one of the jitter bugfixes mentioned above fixes only this specific bug on slow player speed.

There is also the possibility that the jitter is caused by lag due to too many events or too complicated parallel processes - does your jitter also happens on small maps?

Some people (random) also experience jitter on some systems, while others do not. In case you still haven't, try sending the game to a few other people and let them test it and see if it jitters for them.

I notice that you say that it is more stuff being added, I presume events.  If that's the case how many events can you create before the effect starts and how many are moving events and or spend a long time as autorun/parallel process?

 

[Engr. Adiktuzmiko]

@headdie - that depends on the computer where it's being run... Normally, it depends on how powerful your CPU is since that's what RM utilizes. Though in some cases, people who have really good CPUs still have problems with jitters and FPS drops. For most the problem was with using an AMD processor (somehow) while for some it seems to be totally random. Some laptop computers (like mine) also encounters slow down during charging because they limit the power sent into the system if you're using the computer while the battery is still charging.

There are no definite numbers, because it depends not only on the computer (as said above), but also on what those events are.
With pure decorative events, you can add a few hundred before anything happens even on middle class computers, but a single badly designed parallel process can bring even a high-class computer to a full stop (I once tested that with an event that was intended for heavy load).


If you have any parallel processes in your common events or on your maps, the only way to test for this is to disable them one after another and check for game speed after each disable.

 

[AwesomeCool]

Sadly, I did not add events to the map yet at all (besides 10 decorative events).

The jitter seems to occur more frequently when the character is running and is not really random (passing certain points always causes jitter).

I do have an AMD processor (on the stronger side) and am starting to get desperate.

 

[Andar]

and what about your common events? They could also cause lag or jitter as I said above

 

[AwesomeCool]

I have yet to get to event building in my project yet.

I am just trying to make the maps pretty before I do that.

My fps does not drop when a jitter occurs (always at 60) and can sorta be controlled with lots of efficiency improvement scripts

There were some posts about the problem with AMD processors:

I tested my game project on my friends laptop that uses an Intel i7 processor and it still jitters.

I created a new game and used one of the sample maps and it jitters on both.

The only thing I can think of is rpg maker and windows 8.1 not getting along.

(is there a way on steam to completely reset the rpg maker program to its completely default state, i do not get the bug fixes auto-installing like theo's does anymore? I use to though).

 

[Engr. Adiktuzmiko]

Based on the thread by Commotion (if I'm right) he also has problems with Intel i7... It was on that thread I think that it seems that the issue seems to affect random people.

The only thing I can think of is rpg maker and windows 8.1 not getting along.

I'm using Windows 8.1 with a core i3 and it works fine for me...

Try reinstalling?

 

[AwesomeCool]

Re-installed rpg maker (no improvement) and tried a third computer that had less jitter, but it still was there (it was my old laptop).

I too have this issue. The jitter is independent of FPS, as it occurs at 60 FPS, 30 FPS, any FPS really. The jitter can be made less noticeable with smaller maps, fewer scripts, anti-lag scripts, etc, but never removed. This jitter is not only noticeable on my main PC, but on my laptop, my previous PC, my previous laptop, and most people who have tried the game out also notice the jitter. However, not all RPGMaker games jitter, my game for IGMC didn't jitter, and most games I downloaded through here and for IGMC didn't jitter. I've tried many different things to figure out what is causing the jitter (made my own topic here not terribly long ago about it), but alas, I have not been able to come any closer to a solution, nor anyone else.
