Sorry to revive an old thread. I'm curious if gpu core/mem clockspeed transition from idle clockspeed to low level 3d clockspeed is causing the stutter..
It kinda works like this with my 2080ti :
- I launch any web browser that uses smooth scrolling
- I start scrolling the webpage
- I stop scrolling to read the web page
- If approx 3 or more seconds has passed since I last scrolled, the nvidia card will reduce in speed and eventually idle at 300mhz core/101mhz mem, as there is no activity on screen
- I scroll the page to read further
- As soon as the screen moves, the first scroll of the mouse, the nvidia clockspeeds instantly boosts all the way up to 1350mhz core/1750mhz mem (big jump in speed) as the gpu is now being utilised
- There is a stutter when the card boosts from 300/101 to 1350/1750

- After a few seconds, the gpu and mem clock speeds will gradually reduce in speed
- And this continues to happen each time I stop scrolling, wait 3 or more seconds, then scroll again.. Annoying!
I have observed this same activity in the xbox app and the microsoft store. In both of these apps, after 2-3 seconds of scrolling inactivity, I scroll the page and instead of a stutter, the framerate appears to drop to 1/2 or 1/4 for a second or two.
Run gpu-z in the background (or any other app that monitors gpu speed) and monitor the clockspeed of your gpu core + mem, does the gpu clock and memory clock spike when each stutter occurs?
I switched off smooth scrolling in each web browser - that had it enabled by default, as random stuttering annoyed me too much. There is another workaround for nvidia users (not sure for Ati), and that is to set each app to prefer maximum performance power plan in the nvidia control panel, this stops the clockspeeds from fluctuating after a period of inactivity, and stops the stuttering/slowdowns.
