Maplestory jittery

My problem is basically that maple story becomes jittery in it's frames. I've capped the frame rate to run at a maximum of 75 frames a second and that kept the v-sync issues and all that other tearing issues at bay. But now the frames jitter after about five minutes of playing seemingly skipping frames altogether, and just plain rough output of frames.

Highly annoying and i can't find a solution, hasn't happened to me before. the only way to fix it is to play in windowed mode, which i can't do because i'm basically blind

Computer specs:
2x 4850 radeons (drivers up to date)
4 GB ram
Screen is 1920 x 1200 and stretching maple to fit the screen
quad cpu @ 2.4 Ghz
uh plenty of memory
XP

did you run the setup.exe in maplestory's folder to get the right monitor refresh rate?

i just tried that, it still gets the jitteryness on. seems to happen after i enter a different map.

Are you doing a lot of work with your hard drive while playing the game? Try deactivating outside processes before playing the game.

or change the screen to 600 x 800 and play in windowed

hmmm i only have itunes open and google chrome. the disk light doesn't flash too much either.

playing in windowed mode fixes it, but i realy don't want to have to play like that :/

I must say, I have the weird lags / jitters now too in maple (Nvidia 9800GT should be able to play maple....)

V-Sync at 60Hz, setup is correctly at 60Hz now too...

Trying to fix this somehow... it's really odd... other (extremely heavy) 3D games seem to run quite ok... It's only 2D Maplestory that's the problem... -.-

Ever since yesterdays patch I have been getting strange jitters too. It happens in seemingly periodic 5-10 second intervals and gets annoying really quickly. I've tried everything I can think of to help it (disabling anti-virus/firewall, defragmenting and even reinstalling altogether) but nothing seems to work.

I blame it all on Nexon.

I get the jitters too. Only started since the patch, nothing is running in the back ground. At first I thought someone on another pc in the house was stealing my bandwidth, it had that sort of feell to it...but it wasn't that. It has a persistent laggy fele to it.

I jitter as well. MapleStory is at the moment burning my CPU as well. It's weird.

I'm getting this too since the last patch. The screen freezes for a fraction of a second every 15 seconds or so (haven't timed it accurately, but seems to happen at constant rate). Stopped all other programs, rebooted, no different.
I find this type of screen lag annoying, even though I am used to playing with huge internet lag.

Hmmm this is odd, the problem does not seem to be related to graphic cards, since when I massively increase the pre-rendered frames (yay for input lag ), Maple still lags and fps drops still drops... very odd...

There must be another solution to this...

Maybe it's a side effect of maple running inside Oreans' virtual machine.

Hmmmm I have found an easy solution: Just disable V-Sync for playing MapleStory.

Maybe Nexon upgraded to a forced Vsync in Maple's internal engine, or set maxfps at your set refresh rate with setup.exe.

Anyway, with Vsync off, frames keep here at 60FPS all the time, and only drop at places with mass spawn (Galloperia's or whatever their name is). And there is no tearing whatsoever.

Yeah, it almost -HAS- to be that Nexon implemented some maxfps command or internal forced V-Sync.

So: just turn V-Sync of if you have weird lags or maple is slowish.

Er, how do I go about doing all that stuff in setup.exe? I've been kind of afraid to touch it. o_o

It's done on your video card settings...it's hard to say where specifically because it differs depending on your driver, but look to disable vertical sync somewhere.

I don't see a way to do this, other than cutting the appropriate wire in the video cable. So LCD displays do not need a vertical sync signal at all?

There must be another way. Most people are not having this problem. I have seen no mention of it anywhere other than in this thread.

Uh...

You choose to force off the vertical sync from your graphics card control manager.

Hopefully my laptops have the option to shut off V-Sync. My 17 inch might have it, as it uses an nVidia card, but i dont remember seeing that in its options. :c\

Same problem here... tried driver update, didn't fix it. Also tried disabling Vertical Sync, which didn't fix it either. I'm pretty sure V-sync doesn't work with window mode anyway, and I have this same lag while in window mode. Other people I talk to have the same issue, so this appears to be an issue on Nexon's end... hope they are aware of it and fix it soon.
