Unless you have a Geforce 7xx or older it is still very bad as Nvidia is preventing the open-source drivers to work properly on newer cards with their cryptographically signed firmware.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Nothing has really changed for Nouveau yet.
A while back they released an open-source kernel driver for Turing and later (well, really they moved most of the driver to an on-GPU processor called the GSP, and released a kernel driver that's a shim between the GSP and the userspace driver), and that opens the possibility for better open-source drivers in the future (Collabora is working on an open-source Vulkan driver for Nvidia, NVK, and Nouveau is working on making use of the GSP firmware), but it hasn't changed anything for practical purposes yet.
I get screen tearing on any driver other than the Nvidia driver. Also screen flicker. Open source drivers don't work well for me. I guess still have to wait more.
Honestly at this point I think that before Nvidia does something to fix these problems we as users are going to switch to an AMD GPU.
I think we have been waiting too long and nothing happens, Nvidia must have possibly bigger interests than fixing their driver in Linux, I have been since 2020 with Linux and the Plasma experience with the proprietary driver in Xorg is still the same, I could believe that it is Plasma's fault for being badly polished but no, or worse, that it is Linux's fault, when it is Nvidia's fault for their disinterest.
And I know that practically nobody can say overnight that they are going to buy a new GPU to have a polished experience, and that's exactly what I mean, because maybe someone with an average salary will take 5 years to buy a new GPU, and in 5 years the situation with Nvidia will be the same.
one problem imo is that in nvidias view, their “linux drivers” is just CUDA, since that’s the majority of the market share, and those systems are mostly headless compute nodes anyway the desktop experience might not be worth supporting
Nate said that one of the main contributors just worked on big improvement. He'll talk more about it on this week KDE recap on his blog. https://invent.kde.org/plasma/kwin/-/merge_requests/4177
I had read about that but I thought it specifically affected users of 2 GPU configurations, can I benefit as a single GPU home user?
You can try your luck with the Nvidia's open-source kernel driver. I dun think it will work any better than the proprietary one though.
I'm on an old GTX 970 using the 530 proprietary drivers. I have since switched back to Xorg due to various issues with wayland, mostly lack of support for virtual KVM (not Nvidia's fault). I have never tried the open source drivers but this discussion makes me curious to do so.
Also, obligatory Nvidia, fuck you 🖕.
Nouveau works with older cards, performance is still about half last I checked, and most of the advanced features are missing.
Terraria should be fine though, it's a functional driver, just not much more.
As far as i have noticed nvidia open source drivers are still dogshit... Because nvidia got a stick up their ass... Anyway i recommend switching to radeon cards. I use radeon and so far i had not a single problem... Also terraria works well via proton for me
Things might get better with the 545 drivers, which should introduce direct scanout for Wayland.
