Intel runs just fine on Linux, but because AMD gives so much support and lip service to open source, and because Intel is the big bad market leader, there’s a lot of “intel bad, amd good” in the open source community.
My original comment was trying to point out that “Linux Gamers” are an incredibly niche category filled with die hard linux fans with strong opinions and steam deck users. And frankly I’m surprised Intel has ANY marketshare with that crowd.
