Not my experience at all, it works very well with a new Acer laptop I own: the graphics work (Intel Xe - 12th gen processor), audio, touchpad, keyboard (and special keyboard keys like brightness), wifi... All I had to do is to download the firmware with fw_update, nothing more.

Also I was pleasantly surprised to hear they support Apple M1/M2 Macs. Asahi Linux gets a lot of press around here but I had no idea OpenBSD supported it.
