Stuttering issue

[pwyt_]

been having a recent stuttering issue throughout the game and menus but it was functioning completely fine months ago when i first got it. other posts say it's denuvo but idk enough about what it is to say that's the definitive cause.
the game is literally impossible to play now.

Its not denuvo, its shader compilation and sadly has no fix. The issue is when you update your GPU drivers, usually shaders are deleted because get obsolete, so the game must compile them again.

I had stutters when bought the game, but playing stutters gone. Its segas fault for make a shader system like that, it would have been better a system like Horizon who compiles the shaders at the start of the game. The problem of miku game, is has a lot of songs and stages, so on most of the song will cause any stutter until you play all the songs(for example on 2D songs like "Dramaturgy", its nearly impossible to get stutter because there is nothing 3D to compile). This doesnt happen on DX12 where is better implemented, but this game is DX11 and has to compile shaders at this way.

There is a thread to learn about shaders, for those who still dont know why is happening and blame denuvo

What is the solution? Stop updating your GPU unless you have a bug or something, youll see playing the game stutters will gone. Just update GPU 1 time per month or 2 months

If you don't want to deal with any of that you could also try simply turning off your internet while playing. That helps for most people.

I've tried all those methods but to no improvement sadly.

Kind of a shame that it's only happening now because I've literally changed nothing about my pc since I've had it apart from getting a new mouse (which I've tried disconnecting and reconnecting, which didn't help).

Even going offline on steam, turning off wifi internet on my pc and adding the firewall for the game's exe file won't work.

If they're still happening even with your internet completely disabled, my best guess is that you may have a bad USB port constantly un- and re-plugging itself. This has happened to a few others as well. Try playing the game in a window with Windows Device Manager (Just type Device Manager into Windows' Search bar) next to it. If Device Manager "refreshes" (becomes blank for a moment before coming back) at the same time the game stutters, that's the problem. If so I'd recommend a program called USBLogView which can give you more information about it.

If this isn't the case, it's worth looking at a Windows process called WmiPrvSE.exe. Open Task Manager, go to the Details tab, sort by name, then scroll down until you see WmiPrvSE.exe; there may be several of them. Again, play the game in a window next to Task Manager. What you're looking for is if the number of WmiPrvSE.exe instances changes during a stutter. For instance, if there's two instances of it running, then the game stutters and now there's three instance, this is your problem. If you want to see this easier, a program called Process Hacker can help you sort processes by when they're started, so you can see if one has opened recently, and exactly at what time.

Unless you have a potato for a CPU like me. Very few stutters in the 3D PVs but very frequent stutters on the 2D PVs.

Wow, i said because 2D songs are literally a video, so they dont need to render nothing in 3D so no shaders are required.

For curiosity what CPU?

Looked at the WMI process and there were 2-3 instances of it when it was running; ended both tasks, reopened the game in "with frame" display and it only has one instance of WMI and seems to be working fine (no stutters on menu or in rhythm game).

I can't play the game in fullscreen or else i need to switch to "with frame" display and reopen it or it will start stuttering again. Not sure what's the cause since only one WMI process shows up on task manager, even when reopened, but I'm just glad I can play this game now albeit not the best quality.

For curiosity what CPU?

AMD Phenom II X2 555 running at the base clock rate of 3.2GHz
Video encoding takes quite a bit of processing power compared to the 3D PVs. Even with a mod that reduces the resolution of the videos from 1080p to 720p, the game uses around 80-100% of my CPU during video PVs and the 3D PVs are usually at 40-60% CPU usage, with the exception of 2 of them (Decorator and Catch the Wave, which I have terrible performance in and it is almost always at 100%.)

My GPU is a lot more powerful than the rest of my system and is heavily bottlenecked. I have a GTX1050ti. So no issues on the graphics card front and I have not noticed any issues with shader compiling.

Could it just be that it runs better in windowed mode? I always play on borderless fullscreen because true fullscreen causes too much input lag.

Either way, good if it seems to be working better. The issue with that process is that it likes to pop up randomly, so I'm not sure how long just killing it once will really help for. If you're convinced it's the problem, the guide I linked earlier has instructions to temporarily disable it completely. It's a bit convoluted, but once set it up you can use a batch file to automatically apply it each time you want to play.

Tested it a few times now by opening, playing a song or two, closing then repeating and it's working fine now without duplicating WMI processes.
I'll probably update this thread or something if it decides to stutter for the fun of it later. Thanks for the help, soup

GPU is ok for this game but CPU is a miracle it works. I think i had that CPU 15-20 years ago +/-, you surely amortized it

I used to have a lot of trouble with 2D PVs too but I downloaded a mod which replaces all the videos with their 720p versions and I don't think I've had as much trouble ever since. There are many good mods for us potato-ish PC users, I'd suggest you look for some in gamebanana.com

Update:
So it's been almost a month and windowed "with frame" display of the game is working mostly stutter-free but will occasionally have a 2 frame stutter after a random amount of minutes or hours but hasn't stopped me from getting a fc so i'm not gonna scream over that yet. It might be steam doing its updates that's causing this as I set the timer back to its default value in debug after trying one of soup chan's possible solutions.
Tested if fullscreen was working (trying the theory of turn-it-off-turn-it-on) but it was super stuttery on the title screen alone, never mind the actual game. "No frame" doesn't work either without stutters as if it was in fullscreen for some reason.
