Emulator

Try looking at this from another perspective if you can. If you were someone who worked on the emulator, is there any information in this report that would make it easy to fix? There are several possible issues that could cause it to stutter like that.

If you play through a stage/song a second time and there's no stuttering, then it's shadercache. If it stutters exactly the same, it's something else. The only other things I can think of at that point would be disc load times maybe being too slow (Try turning on Speed up Disc Tranfer Rate in game properties?)

Otherwise, maybe someone else can verify this and we can narrow down possible causes.

is not shader cache since the game runs smooth by the first time you run it, i saw someone comment that the issue is possibly the game triyng to connect to nintendo wii wifi, and i belive that is the reason, because other users report the same issue here, and there is videos on youtube about this, so my question is, if it is in fact a problem with tha game trying to connect to wii wifi, there is a possible fix for that?
PS: im leaving a video that shows the problem, a friend of mine also have this same issue on his PC, runs smooth with this randoms freezes.

hangs at 0:30, 1:03 , 1:40 , 2:15 and 2:48

Actually, that video is pretty interesting. I wonder if it's querying something and freezing up...

Did you try the Speed Up Disc Transfer Rate option?

yes, i've run some tests configuring diffenrent types of settings and nothing seems to work, i've just formated my PC from windows 8.1 to windows 7 and i'm going to make a series of tests in both warriors of rock and GH 5, seems like only this 2 games from the franchise have this problem.

I'm running the latest dev-version of Dolphin (4.0-8122) on Windows 10 Pro x64, Intel Core i7 4800MQ @ 3.6GHz, 16GB, 128GB Samsung EVO 840 SSD with Windows and Dolphin+Iso's, nVidia Geforce GTX870m 6GB

GH:WoR NTSC: Didn't touch game properties...

Settings: OpenGL 1080p, VSync OFF, auto aspect, internal res 3x, noAA, 16x AF, Scaled EFB+Per-Pixel Lighting+Force Texture filtering @on, Ignore format changes+store EFB to textures @on, texture cache set to FAST, XFB @Disable, Fast depth calc+disable Bounding box@on, progressive scan@on, General: Dual core+Idle skipping @on, CPU Emulator @JIT Recompiler, Audio: DSP LLE Recompiler, Backend OpenAL, Latency 2. Using Ripped DSP roms Wii: Use PAL60 @on, aspect 16x9

All seems working correctly without any lagspikes @ 60FPS, I used to have the 1-2 second lagspikes in Band Hero and GH:WoR a few revisions ago but they seem to be completely gone now. Game plays perfectly, ingame calibration is on point. Playing with official GH:WoR PS3 guitar, I'm able to 5 star most songs on Expert with a Full combo here and there.

So I investigated this myself a lot more and found that this is a hardware issue on certain harddrives going to sleep during gameplay. Verified in Guitar Hero, Rockband, and Band Hero. Marking as invalid as such. I apologize for the delay.

FWIW, it appears to very large harddrives with power saving modes that are doing this.

hello, i'm the one who made this thread (lost my account so i made another lol) do you have any tips of how to bypass this HDD problem, ive downloaded a software named HDPARM that supposed to be a fix for this power saving, but in the event of this not working, if there is any other way to fix it, i'll be happy to know! btw thanks for the reply, sorry for my delayed reply haha

It's no problem. If keeping the harddrive active doesn't work, then I'll be willing to reopen this. In the time since this issue was opened, I've gotten most of the guitar hero games so I can more intricately look into things. Marking this as a new for the time being so you can look into it and I don't forget to check back in.

i recorded GH5, it's not the same game but it's the same engine that warriors of rock uses, and it have the same problem, i made sure to emulate in a way that only this problem is shown, i have put the game in training mode and played the same music a couple of times so shader cache don't stutter the emulation, also had HDPARM active and the HDD power saving on windows is off. heres the video.

Please don't enable Speed up Disc Transfer Rate when trying to show that this issue is valid. It can lead to stuttering and decreased performance depending on the circumstances. My guess is that it wouldn't cause stuttering in the pattern you're experiencing, though.

when i reported this issue a while back when this thread use to be on google, i didn't use speed up disc transfer, i only used because JMC4789 sugested for me to try, as you can see a couple comments above, and regardless of speed up disc transfer on or off the same stutter is present, on my video and on the other video from another channel that i've linked before, and again, it seems to be a problem only on these games (GH5, WoR and band hero) since the other games from the series that use another engine don't have this issue.

Based on https://forums.dolphin-emu.org/Thread-fps-stays-at-60-but-game-stutters-every-so-often?pid=433287#pid433287 and https://bugs.dolphin-emu.org/issues/7742#note-7, the issue seems to be related to connecting to the internet, like one of the comments on this report mentioned.

Can someone test if this was fixed in 5.0-15009 -> https://dolphin-emu.org/download/dev/006fc99e8e6c475bcdbb17d79000681f3892d67e/
