Windows 10: How to fix in game stuttering??

I’m having the time of my life gaming in 120+ FPS games high FPS games but i run into stuttering/FPS drop . I ran a program from my pc called resource monitor to find out what’s going on & seen that the game only starts to stutter/drop FPS when my disk usage spikes really high. The Kb sizes are like 1,000,000 - 2,000,000. This happens almost every time when looking through the scope of my weapon or getting into gun fights. I have optimized my nvidia settings by adding games there & selecting high nvidia processor, added my games to windows graphics settings & have selected h

HL2 stuttering fix

Valve has released a Patch for Half-Life 2 which is supposed to fix the sound problems people were having. In most cases this is related to video memory texture trashing.

 

High end build, stuttering in every game

Hello, this is my build:

• i5-6600k
• ASUS MAXIMUS RANGER VIII
• MSI GTX 1060 6G
• Samsung SSD 850 evo 250gb
• WD Caviar Blue 1TB
• G.Skill Ripjaws V 3200 DDR4 (XMP profile)
• Dual monitor: Zowie XL2411 144hz + BenQ GW2260 60Hz

I get stuttering in the following titles:

• Rocket League: every time a new player join a match the game freeze, also when V-Sync is on I get random lag from 144 to 130 and then the game continue to run smoothly.
• GTA V: random stuttering Online and fps drops, V-Sync on.
• PUBG: random stuttering, V-Sync off.
• Rust: stuttering when loading chunks with fps drops.
• Ark: as Rust.
• Total War Warhammer: random stuttering in the strategic map, V-Sync on.

What I've done till now:

• Tried every graphic settings.
• All kind of Windows 10 optimizations like Performance mode, Xbox game mode off, disabled unnecessary services and tasks, no antivirus (Windows Defender on only).
• Hard drive defragmentation.
• Nvidia control panel optimizations for every game like Thread optimization, tried several v-sync modes, etc.
• All drivers are updated.
• No pending Windows updates.
• Temps are fine, GPU and CPU never go above 65C.
• Shadowplay overlay off.
• Playing with one monitor at once.
• Moved games from HDD to SSD.
• Tried different version of GPU drivers.
• Disabled the page on the HDD and fixed its size on the SSD with the reccommended value.
• Memtest for both RAM stick at once (8 pass each no errors).

What I've not tried yet is to reinstall the OS... benchmarks and performance in game are ok and in line with every other user... do you have any suggestions? Could it be network related? How can I analyze the stuttering?

PS: I'm testing with Latencymon and doing some screenshot of gpu and cpu usage
