Are they some graphic card benchmark for linux environment ? From my windows experience, drivers are important, and often underestimate. My linux gaming experience is very bad, lots of my game are unstable, and others use a lot more resources than with windows. However, when I ask people, some of them have no issue at all, even with a similar environment (Debian + Steam). I may consider buy specific graphic card to stay on linux, but I couldn't find any clue to know which one are more adapted.
Thx for your leads !
Go AMD. The open-source drivers already provide the best performance compared to the closed-source ones, and are included in the kernel and Mesa, which means the cards will work out of the box. For the best performance and latest drivers and optimizations you should switch to a distro with more up to date packages than Debian if you plan on buying a current gen card tho. For example, Fedora is a very good mix between working OOTB, ease of use and bleeding-edge packages.
nVidia is... difficult. The open-source drivers are getting better but are still way behind closed-source drivers, and each closed-source drivers version only works with a single kernel version. It might work OK as long as the drivers and kernel are kept in sync (I think Pop! or Nobara have nVidia specific versions for this reason), but otherwise each kernel upgrade is a risk. Plus nVidia drivers are basically shit with Wayland and cause a ton of issues.
Intel has a good track record with iGPUs so discrete cards should be as trivial to use as AMD ones, if more at the entry-level performance-wise.
Are you sure this is true? I make no attempt to keep my kennel and driver in sync and have never had any problems at all. I'm pretty sure you're wrong about this
This is kind of true, but overstating. I use nvidia with Wayland also the time and, apart from some games, it works really well. Many of those issues will be fixed when explicit sync is released.
That all said, is she that AMD is currently best for Linux.
