Community Rules
Follow the Code of Conduct
All posts on pop_os must adhere to the Pop!_OS community Code of Conduct. https://github.com/pop-os/code-of-conduct
Be helpful
Posts to pop_os must be helpful. When responding to a user asking for help, do not provide tongue-in-cheek responses like "RTM" or links to LMGTFY. Linking to direct sources that answer the asker's question is fine, but it's advised to provide some explanation as to how you got to that source.
Critique should be constructive
We within the Pop!_OS community welcome helpful criticism or ideas on ways to improve. However, basic "It's bad" or other simple negative comments don't help anyone fix anything. When voicing a complaint about something, try to point out ways the complaint could be improved or worked around, so that we can make a better product for it.
This rule applies to both Pop!_OS and its projects as well as other products available from third-parties.
Don't post malicious "advice"
It can be funny to joke about malicious commands, however this is not the venue for it. Do not advise users to run commands which will lock up their systems, steal their data, or erase their drive. Examples of this include (but are not limited to) fork bombs, rm, etc.
Posts violating this rule will be removed, even if the post is clearly in jest. Repeated offences may lead to a ban. You may understand that the command isn't serious, but a new user might not.
No personal attacks
Posts making a personal attack on any user will not be tolerated.
No hate speech
Hate speech of any kind will not be tolerated. Any violations will be removed, and are grounds for a ban.

Are you using multiple monitors? With X11 multi-monitor setups one of the monitors always tears if the framerate aren't multiples of each other (e.g. 120Hz + 60Hz works fine, 144Hz + 60Hz results in tearing with one of them). This is also the case with variable refresh rate (FreeSync), but VRR shouldn't be an issue as it's not enabled by default on X11 iirc.
You'd have to manually enable Wayland, because PopOS disables it by default (does not show in the login menu/GDM). Keep in mind that PopOS is based on Ubuntu 22.04, which is quite old at this point. Wayland might not be as good of an experience for you because lots of improvements happened over the last two years.
PopOS will release their new COSMIC wayland desktop environment with updated packages in a few months, which should work well for gaming and fix your tearing issues.
If you want to try whether Gnome Wayland solves your issue, you can edit
/etc/gdm3/custom.confand setWaylandEnable=true. After a reboot you should be able to select Wayland in the bottom right corner at login.Awesome, this was super helpful! I was using multiple monitors, so that may have been my issue, but actually just decided to go back to one the week. I haven’t had much gaming time this week, so I’ll see if the tearing is resolved.
Super excited for COSMIC!! I probably won’t upgrade right away, but the progress has looked awesome.
