This is a very capable graphics card,

Noooo, it's the bare minimum card one would need in order to call something a "dedicated GPU." It's the mobile version of the 1030, and honestly a 1030 isn't that great to begin with. Just being honest here, not busting your balls.

If you're maxing out your GPU (I could see it clearly in one test, at least), it's going to cause stuttering. Your GPU simply doesn't have the overhead for those benchmarks to run smoothly, and it may even be throttling down a bit due to overheating (didn't spend a whole lot of time on the test videos, but I don't recall seeing any GPU temperatures). My advice would be to download something like MSI Afterburner and monitor your VRAM usage and GPU temperatures and start there, as they're the most likely culprits.

I was thinking GPU-Z, but Tzaar's suggestion is also good.

Try to identify everything that changed between running well and stuttering. Maybe a Win10 update, a new AV program, etc.

This one case will be hard to crack, but from my experience, I can say its a faulty GPU (this shit happens more often in laptops since there is worse cooling system than in regular PCs).

I see you mainly did software-based changes, and I have a few more:

1. Shuttering may happen by bottleneck which is your HDD, try installing a game on SSD and check results again.
2. Check your SSD / HDD health with CrystalDiskInfo (not a Mark one)
3. The final option will be "nuking" your whole system, which is:

1. Make a backup of your SSD with a tool like Acronis True Image 2020 (it have a 30-day trial) [just in case]
2. Wipe SSD and reinstall with a fresh copy of W10, install drivers and that one game and check again if it shutters, if it does restore with image you made before

I have the same gpu and had this problem a while ago. Reinstaling DMC5 game ready drivers solves all issues for me.

Hi, my opinion is that the problem is not with the video card, but with RAM. Try testing it with AIDA 64. I would recommend lowering the RAM voltage using the BIOS. It seems to me that your motherboard used auto-voltage for RAM and this is the reason for freezing.

Dejabu(｡･Θ･｡)…I recently replied with a similar story.

Maybe the Windows update is suspicious...?

I have the same problem with GeForce GTX850M.
But this freezing thing with decreasing fps begins after several hours of playing with GeForce card. First the place in the laptop where the card is installed becomes hotter and all that St. Vitus’s dances begins.
After that I finish playing, gave my laptop half an hour of a rest & start playing again. And everything repeats in several hours.
Does anyone know could it be connected with graphics card cooler?

UPD
I’ve tried to return Windows to factory settings, reinstalled driver from NVidia site, but it’s all the same.
Laptop is about more than 4 years old, I suppose.

I had a similar issue early last year, and would see regular momentary pauses/pulses in certain games and in the Heaven benchmark (which would also show the framerates tanking then resuming).

In my case, the thermal compound on the GPU had dried up too much and was no longer effective, so it kept throttling the GPU every 2 seconds or so. Removing and reapplying fresh thermal paste fixed it, but this was on a desktop card, so it was fairly straightforward. It might be trickier to do on your laptop.

I have no magic answer for you, but here are my experiences with similar problems. Maybe it can give you some more ideas to try.

On a desktop PC, GPU would randomly go into "Super Slow Motion" mode. It was due to thermal throttling. It was so slow, even desktop wallpaper would take about 10 seconds to draw on the screen if I minimized a window. After inspecting, I found that a heat sink had fallen off of the card. No stuttering in this case, the card just turned into a potato whenever I used it for more than a few minutes.

I had a stutter on my gaming laptop, it happened about every 30 seconds when plugged into wall power. In addition to making games hard to play, I also did audio recording on this laptop and my recordings would have a stutter at the same frequency as the gaming stutters. It ended up being due to Lenovo battery management software. Basically the software works by turning battery charging off/on in order to manage lithium-ion battery health (keep it around 50% when plugged in, to maximize battery lifetime). So it seems every time it toggled between modes, I had a momentary stutter. This software operated independently of Windows power settings, my Windows settings didn't seem to make any difference.

Once I had a horrible Nvidia performance in only certain games and it was driving me crazy. The games used to work fine and suddenly they were nearly unplayable. I downgraded Nvidia drivers until I found one that worked. I literally tried every single version in reverse chronological order until I found one that works (over 1 year old, at that time) , and I simply never updated the driver again after that.

I also helped a co-worker figure out a some stutter problem that was caused by their webcam face unlock software feature, when that was uninstalled the stutters went away.

And finally, my laptop at work had bad video performance problems with multi-monitors and that was solved by a BIOS update. (It is conceivable that a BIOS update could cause the problem to present itself, too!)

good luck!

sounds like a thermal problem
have you monitored the gpu temp?

Try turning off game mode

Hm, I won't be of much help here but I just wanted to let you know I have a very good PC and PremierPro and AfterEffects stutter for me as well, I have to set the output to 1/4 on the preview for it to run smoothly.

But since your games are also stuttering you might have an actual issue.
Have you checked your PSU? A friend of mine could run games at very good graphics then a year down the line couldn't anymore, his PSU broke at one point and after replacing it he could run games at very good graphics again. So the PSU might be outputting to little power for your GPU? It's possible, but it could result in the PC restarting or turning itself off as well. Depends on your set up.

Seeing as you already formatted I would think its a hardware fault OR you have a virus that stayed in the files, or maybe even a bat file that is running itself and taking up a lot of your resources... its possible...

I may be wrong, but in that video it seems the stutter only happens whenever the temperature is >= 82°, which is also in sync with the memory switching between 2500mhz and 3000mhz

So I started playing AC Origins recently and I had the same stuttering problem in this game(1050 ti). After some research, the solution was rolling back to older game ready or studio drivers. I installed 446.14 game ready driver, and now it runs smoothly.
Steam discussion

Had the same problem (frequent 2-second stuttering) in some "demanding" games (Witcher 3, Battlefront 2, Division 2, GR: Wildlands....), no matter the resolution and graphic detail.

After uninstalling my anti-virus, it magically went away and I'm now happily 60fps'ing in 1080p in my potato (laptop i5-8300 + 1050).
Apparently, some anti-viruses are overly aggressive while protecting your PC and are constantly scanning game files.

Try to alt+tab out of your game and check the control panel to see if your anti-virus is consuming a lot of resources (cpu/memory).

I found a thread where people describe throttling problems with the MX150 and either a 8250u or 8550u. It may not be exactly the same issue, but I guess it's worth a shot to read through them and maybe try out a few of the recommendations there.

https://www.nvidia.com/en-us/geforce/forums/geforce-graphics-cards/5/262139/geforce-mx150-performancethrottling-issues/

I am not sure what to make of your video. Thermal throttling should not look like that. The jump in RAM frequency from 2500 to 300MHz seems odd (but might be a measurement issue because of the short freeze?). I personally think undervolting the GPU might make sense. That way you can see if the GPU can handle a full load, if it does not pass certain thresholds (like 82 degrees).

It's most likely the GPU running too hot. Your video says 80° and more, so the GPU throttles to safe itself. It happens to my PC if I turn off my GPU fans and forget to turn them on again before playing a game. Basically you're expecting too much of your GPU or it's not getting enough cooling (depending on how you want to view it).

Don't have anything specific for your laptop, more of a general remark (that may or may not be applicable in this case).
Many times laptop manufacturers have their own version of the graphics driver - I believe this is mostly due physical limitations in the machines that forces them to disable or alter certain functions to lessen impact of heat, or to make a certain video card run with other components that it's not really meant to be run with, or to make it consume less power so they can keep the power supply small, etc. If this is the case on your laptop, and you then upgraded to latest driver from card manufacturer (instead of latest from laptop manufacturer) you possibly bypassed these restrictions and therefore made it stutter as it fully activated all functions and tries to do it's job but don't have the resources to do that.

Just check so this isn't the case. Should be clearly stated on either your documentation that followed the laptop when you bought it, or via manufacturers homepage/support.

If the stats shown on this video are accurate, the graphic core is running overclocked but the memory is underclocked.

Video stats:

Graphics: 1911 MHz
Memory 2505 MHz

Real specs:

Check with GPU-Z while running the test to confirm this info.

right click, personalize, choose composition with aero off, next change to one with aero on, now check if stuttering changed.

I have little doubt. Its the temps.
Either CPU or GPU overheat and downclock, usually on the same heat pipe so irrelevant which one is it.Could have started because of dust accumulation or bad thermal paste.,
Open clean and repast.

Did you try a speech therapist? :p

Most things suggested are usual standard replies and most of the time not a solution however so much can have happened which we don't know about, stilll has warranty on it, or contact asus, check their forum? Most likely if more people had such issues they will know more then us.

Update:

So it turns out that it was not actually because of the heatpipe popping off of the board, because that is now fixed and the problem still presists. The technician guy told me that the GPU is broken, and the whole motherboard needs to be replaced, and said that buying a new laptop would be way worth the money. I still have a warranty, so the warranty company can pay me 60% of the price I bought the laptop for me to buy a new one (I need to let them have my old one tho). I was thinking of buying an Asus ROG Zephyrus G14, the rtx 2060 version. Sounds good or no?
