Hello,

I have been asked to solve a stuttering problem.

My friend has this kinda old rig by my own standards, he use to play p3D v4.5,  it has the following specs:

• Amd ryzen 7 5700X
• 32 GO of ram, the ram being DDR4-2400
• An nvidia GTX 1660 Super

He usually plays with his meta quest 2 and some warthog hotas, when playing all is going good but suddenly for 2 or 3 seconds the graphic start stuttering, i can see it on the screen, i opened the task manager to see what is going on, the card is usually around 60% of usage at 60° temperature, from time to time i see a drop in usage when the stutter happens to something i would say around 50%, and then go back to normal after the stutter, it seems to be something happening periodically even when the sim is on idle, like running but we are not playing.

So right now i'm wondering if the rig is not bottlnecking somewhere, and if not what i kinda to find the root of these episodic stutters, i just tried to play again right now but nothing happenned, not stutter, i can't seem to reproduce it.

Any ideas people.

Many thanks.

Just a thought: as your graphics card is not a monster (don't know your resolution) and modern webbrowsers use it for rendering, maybe an open webbrowser in the background rendering advertisements ? Or a scanning of a security suite from time to time ?

I would recommend process explorer or MSI Afterburner to get deeper in detail.
