Hello,
Since im gaming under Linux, im wondering why i have horizontal line at the upper half of the screen when i playing games with Vsync On.
When i search for a fix i read always about the Force Full Composition Pipeline around the nvidia settings, that demands always Max Powerconsumption on the GPU.
So is there anything else what i can do? Why isn’t Vsync not working? Or is there a way how to enable/disable Force Full Composition Pipeline with a simple on/off script?
I wanted to add, that i have absolute no screentearing on my Desktop or when watching Video’s. Im using X11 btw. Its only a gaming problem.
Screen tearing appears when your graphic card of the host machine falls out of sync with the monitor connected. Simply put, this happens because of the mismatch frame rate. What does screen tearing look like? It’s when different portions of the image are showing different frames. This is more often seen in fast-moving scenes with multiple objects, for example, racer games, or explosion scenes where the motion requires higher FPS for a smooth presentation.
One of the option is:
Cap the refresh rate
If your monitor does not support the refresh rate coming out from the game, cap the refresh rate so that the image won’t exceed the limit that your monitor can handle. You may find the settings in your game console, the game app, or your computer settings.
Use in-game settings: Many modern games have built-in options to cap your refresh rate. Check the video settings of your game to see if this option is available.
Set up V-sync: V-sync (Vertical Synchronization) is a setting that synchronizes your GPU’s frame rate with your monitor’s refresh rate, preventing screen tearing. Enabling V-sync will cap your frame rate to your monitor’s refresh rate.
Related to what Kobold recommends:
I’ve had issues using the command line for setting FullComposition, you can use the tickboxes in NVIDIA settings (if you have it installed) to do the same thing.
NVIDIA Settings >
X Server Display Configuration >
Advanced >
Force Composition Pipeline >
Force Full Composition Pipeline tickboxes.
I’d add that certain games respond better to just Force Composition Pipeline (Eve online, Bioshock for example) whereas other games respond better to both options being used (Warcraft, World of Warships etc.).
All assuming you’ve got refresh rates set right in-game compared to the monitors set refresh rate.
The problem is that i don’t want to always going in the GUI and playing around. Thats to complicated to always open X Server when open a game and closing a game. A batch script should work much better.
Certain games can be weird, like they’ll have specific limits available in the games options so if the game is currently limiting itself to 60hz and the monitor is 144hz you might get weirdness.
Generally I don’t get issues with modern titles but a few older/obscure games running in wine for example won’t remember the options I’ve set and default to something else each time they’re started.
Not sure tbh, if it’s just a composition option then I’d assume it doesn’t really do much to power consumption…if anything.
Your framerate/settings are more likely to change power usage from what I understand, a decent modern card might be running a game at 60fps and barely using it’s resources but changing it to 144fps/unlimited could max out the same card…then there’s resolution, rtx and all that.
I know they increase the temperature for me, 60fps max settings would show the card at ~55-60c and when I set framerate to unlimited the temp goes into the 80s. That’s gotta be using more power.
But my card is old so I haven’t looked into it yet.
