Graphic card p-states, screen stutters
Posted: 24 Aug 2020, 10:15
Hi Blurbusters,
When I'm scrolling the web (any web browser) or using google maps in the browser, the screen stutters each time my GPU core clocks boost from low to high speed. The memory and core clock speeds of my 2080ti keep jumping to 1350/1750, with the smallest amount of activity, such as scrolling a webpage with nothing but text, and when that clock speed change happens, for some unknown reason, the screen stutters.
I would like to know if any of you guys with an 2080ti Nvidia card and a high refresh rate monitor can reproduce this issue. You need to be using the default power plan in Nvidia Control panel. Gsync can be on or off. Please take a minute to test this out.
1 - Open Firefox (any version) or Edge (new Edge)
2 - Open Gpu-z or a Gpu monitoring utility, keep it on top so you can monitor the core/mem speeds
3 - Open Google maps, go to any location, zoom out so you can see the earth
4 - Wait a few seconds (approx 3-9), let the Nvidia card drop the memory clock speed to around 101mhz
5 - Drag the map once, any direction, with the mouse cursor
6 - Repeat steps 4 and 5 a few times
Question 1 -
After dragging the map to a new location, look at GPU-Z, do the core clocks instantly boost to 1350mhz/1750mhz (low level 3d clockspeed)?
Question 2 -
If you answered yes to question 1, at the same time the clock speeds boost to 1350mhz/1750mhz, is there a screen stutter? Judder?
This is what is happening when I'm browsing the web or using google maps. I'm not sure if its my hardware at fault, as I have tested two 2080ti's and a GT710, and I can reproduce the stuttering on two totally different machines, intel 4770k/ryzen 3700x, ddr3/ddr4, corsair rm850/corsair rm850x, tested an handful of different Nvidia drivers and also reinstalled Windows 1809/1909/2004 on both machines at least 3 times for each version. I have tested two different monitors too. I tested onboard intel graphics on my intel machine and the stuttering doesn't happen, the intel card doesn't boost in speed at all. It's only happening with my Nvidia cards, however I haven't tested an Amd card yet. I initially thought it was a Firefox issue, and started testing different configurations, such as web render on and off, testing Nightly builds which the devs recommended, which never worked, but I have been able to reproduce it on all web browsers. The issue seems to be the Nvidia card is unable to smooth transition from a low clock speed to a high clock speed without causing a stutter.
The only way to stop the stuttering is to force my Nvidia card to prefer maximum performance, locking the core clock speeds to a minimum of 1350/1750, which shouldn't be necessary.
If other people are seeing the same then I can put my mind at rest.
