Screen is laggy and stutters even after changing settings


New Member
I tried changing my settings in Linux because it was not running at the right framerate and I am getting screen tearing but nothing has worked so far. I ran the XRANDR command and changed the settings to a higher HZ but the monitor is still extremely laggy and stutters. What could I be doing wrong?

What linux? What kernel? What video card? What monitor? What resolution?
What video drivers? A lot of things make a difference.


I actually get better performance from Linux these days than I do from my Windows box.
( Admittedly, it is nVidia 2080 vs nVidia 1080 ) .. but even so.


Remember your monitor has to support the refresh rate you type in, if you type a higher number, it may slow you down or even break. Also what is the pixel color change speed 4ms or lower is good.
This monitor is 1ms GTG. Even the cable and monitor can make a difference. For example one monitor I have supports 144Hz using the display port, but only 60Hz using HDMI.
Another monitor I have supports 60Hz in 2k (QHD) mode, but only 30Hz in 4k mode.


All these little things like flipping and texture mapping make a big difference.


A newer kernel can also speed things up. I would recommend 4.18 or newer.
I am currently running 5.8.16.

Specs are in the thread.

Go into Synaptic or Muon and install the nvidia-settings package, since you have the nvidia 455 driver installed. I don't know if that is the actual recommended driver, but it sounds about right for your video card. The nividia-setting package will give you a GUI to help you fine tune your setting. The xrandr utility is good, but the native Nvidia stuff is better.

You should also use the Driver Manager GUI in System Settings, or ubuntu-drivers devices on the CLI, to make sure that the 455 driver is recommended for your card.
