Why do some games stutter?

LCD monitors take awhile to draw the image onto the screen (I don't know if that is the correct way to say that). If you try to run it at a refresh rate that is too high it either won't work or it will break the display.

This is weird, my concepts around this matter seem to be wrong then, I'll read a bit and come back later.

Not wrong, just incomplete.

I'm curious if maybe texture decoding is causing the stuttering. See if turning openMP on/off and openCL on/off makes any difference.

Hey, so you've really forgotten about me. My specs are the same as before. I tould you about problem months ago in the Donkey Kong post and nothing's been solved until now.

Only this time I'm using 3.0-371 64bits. I have been using a Phenom II 3.4GHz BE, 4GB RAM and W7 64.

I haven't tried neither OpenCL nor OpenMP this time. But at that time I actually tried OpenCL and got exactly the same results. And I told you that turning off the sound on DK would remove the stutter. But this didn't work with TvsC.

But I'll test those two options and post results later.

Just for the record: OpenCL made NO difference.

I haven't forgotten about you. But you can't expect me to keep track of all of the info. you've posted in various separate threads. Can you post a link to the thread that you're talking about so that I can read your post about the issue?

I'm sorry if I sounded rude. And no, you're not supposed to keep track of all the info. Here's the link: http://forums.dolphin-emu.org/showthread.php?tid=13170&page=60

EDIT: Yes, I bought a new GPU in the mean time: the Radeon 6770. I forgot about this other one http://forums.dolphin-emu.org/showthread.php?tid=13283&page=5

But the "turning off sound" trick doesn't work here.

Sorry about the double post (even if the first post was like 5 months ago). With the recent build 3.0-688 x64 and a new screen (real 16:9 1080p) I re-tried TvsC. The still stutters, but much less than before. It stutters once in the beginning of every fight and once after the first super move is used, it doesn't matter by whom. Regular specials, big combos won't reduce the game speed.
In spite of these two times, the game runs smoothly at 1080p. The game will stutter again if another fight is started.

It could just be the cache building up, try playing a fight you've previously completed on that same build

I've tried entering the same fight in practice and you were right: the stuttering does disappear. However, if I stop emulation and restart it without closing the emu I get a crash. Once I restart the emu and play the game in the same fight, stuttering is back. I guess there's no solution using an official beta build.

I've tested delroth's build with this game in particular and the problem persists. In fact it changes nothing. But I little need to test DK where the stuttering rends the game unplayable.

EDIT1: Not being able to use original discs with the emu is a pain in the neck.

EDIT2: Ok, may my girlfriend forgive me, but I'm in love with delroth. Your build fixed the stuttering in Donkey Kong Returns!! NO JOKE!! Now I can play past stage 2 on the emu T.T
