Windows 10: Stuttering/Lagging In games when a (graphical) things load(?)

Hello guys, I'm Back again in this forum.I'm trying to find solution for this annoying problem for so long time.
My PC Specs is on 2nd System

So When I'm playing league of legends or osu! my frametime/latency of frames are dropping or like mini lagging (if thats what you call it, idk). It happens when on my Spotify Friends activity someone listen to music, someone is typing me a message on facebook. It also happens when I try to stream osu! or LoL in 60 fps and I got this very noticeable mini stutter/lag throught the whole instance of streaming it in 60 fps, which I know i5-8400 is capable of doing it without that mini lag/stutter. It's really annoying and I can't really find a solution. Hope people here can help me.

Windows 10 Stuttering/Lagging with Graphical Glitches


I have installed Win 10 Pro and been using it for a while. I also have a ASUS STRIX GTX 960 OC with 2GB GDDR5 video memory, and 4GB ram. Lately I have been noticing a lag/stuttering after using the computer for a while. Mind that the problem doesn't come on as soon as the PC boots up (the boot up is quite fast). Instead it starts after an hour or so into the usage. The lagging/stuttering initially starts off as some graphical artefact (the text inside a window of an app starts refreshing - it basically vanishes and then comes back on). The problem is only limited to windows of the apps and Explorer itself. After a while the system starts lagging a lot. The stuttering and graphical anomalies appear periodically and the lag is also in sync with this period.

This is the lag at the most extreme

A notepad file




Task manager




An interesting thing that happened is that while I opened the Nvidia Control Panel to take a gif recording, the graphical stuttering immediately stopped. The lag however was still there, but very minute. This leads me to wonder whether the glitch/bug is caused due to a bad Nvidia driver.
The driver in question is 361.75
I know that the driver is problematic but I also read that the newer version 364.51 is also having a lot of problems.
This is the Task Manager after I opened and closed Nvidia Control Panel





However, after the problem still came back (in about 10-15 minutes), I tried the same method - opening and closing Control Panel. This time, the problem still persisted. So maybe something else caused the stuttering to go away. I am not sure of the chain of events that precisely led to this so I couldn't recreate it.

This PC is usually very fast, can run most games on ultra-high settings (albeit at my display resolution of 1366x768) and basically runs without a hitch. However, once this sets in, after a while its annoying enough that I restart it. Then the cycle continues.

I am pretty sure that the problem is software related (maybe bad Nvidia drivers?). The graphics card is pretty new (Nov 2015) so I can basically rule out any graphics card problem. The problem however does show up in COD MW 1 (Multiplayer). The entire screen flashes in sync with the same problem. Basically, if I'm playing the game once this flashing of windows starts, the entire screen goes black and comes back on - there is no lag, just the blacking out - completely in sync with the window flashing. The screen refreshing problem exists ONLY with this game, all others run without any problems

Any help? I am ready to roll back to previous graphics drivers but a clean Windows install is a no-no. I have way too much data to backup

 

Windows 10 Stuttering/Lagging with Graphical Glitches


These are the LatencyMon stats once the problem sets in





















The problem didn't come in Safe Mode - although I only used it in Safe Mode for about 10 minutes.

*I usually only needed to input a PIN password to log into Windows. After booting into Safe Mode it started asking for my password (i.e. Microsoft Account password). It hasn't asked for the PIN since then. Is this normal? Maybe some kind of protection enabled by Windows itself?

This is the LatencyMon stat without the problem:

















As you can see it says that my system has no latency issues.
Something weird I noticed is the difference in Measured and Reported CPU speeds - 1 Mhz and 3293 Mhz. How is that possible? I mean will the system even boot up if that's the actual speed?
There is also and Indepth Latency Test shortcut created by the program. Do I need to run it as well?

 

Windows 10 game stuttering

Not sure what game(s) are giving you this problem but in my experience with Flt. Sim X, I have had similar issues of stuttering and game lag/freezes. Hopefully, others will call in with their suggestions, but mine are:

1. For stutters: happens when my processor isn't able to read/process the graphics on the screen fast enough. As I approach high density airports, I get minor stutters and drop in frame rates. This is due to low processor speed (3.4 ghz) and depleted
VAS (Virtual Address Space) required to run the game smoothly. Solution: increasing my frames to Unlimited helps, but turning down graphics, moving vehicles, etc. brings the most gain.

2. For lag/freezes: I don't experience this, as I make sure that when I boot the computer, I allow up to 15 minutes for it to fully load, with its Services, internet checking, etc. However, when you get a delay or a freeze for some time, then you need
to see what Service, Update, System checking, etc. is going on in the background. Sometimes, Anti-virus software could suddenly start a check or scheduled task could kick in. All these need to be disabled, or at least you need to find out what is starting
while you are gaming, by checking in your Task Manager. This will give you some idea of what is going on in the background.

Hope you make some progress with this.
