I'd say there are two remaining roadblocks. First and biggest is kernel level anti-cheat frameworks as you point out. But there's also no open source HDMI 2.1 implementation allowed by the HDMI cartel so people like me with an AMD card max out at 4K60 even for open source games like Visual Pinball (unless you count an adapter with hacked firmware between the card and the display). NVidia and Intel get away with it because they implement the functionality in their closed source blobs.

Is HDMI really a roadblock to gaming when DisplayPort exists?

It's a blocker if you want to use a TV, there are almost 0 TVs with DP. This HDMI licensing crap is also the reason a Steam Deck can't output HDMI > 4K@60 unless you install Windows on it.

Aren't there some hardware dongles to translate from DP to HDMI?

		Last I checked, even the best ones that are high quality don't support VRR.

Up until a year or two ago, the majority of monitors (and graphic cards) used DisplayPort 1.4 and HDMI 2.1. With HDMI 2.1 (42 Gbps) having more bandwidth than the DisplayPort (26 Gbps).

This is my case with my relatively new/high-end RTX 4080 and OLED monitor. So until I upgrade both, I use HDMI to be able to drive a 1440p 240hz 10-bit HDR signal @ 30 Gbps.

		I had said I wouldn’t upgrade from my RTX 3080 until I could run “true 4K”. I finally got the 240hz 4K uncompressed but it required buying a $1300 Asus OLED monitor and the RTX 5090. It looks amazing though, even with frame gen. Monster Hunter had some particularly breathtaking HDR scenes. I think it uses DisplayPort 2.1? Even finding the cable is difficult, Microcenter didn’t have them in April and the only one that worked was the one that came with the monitor.

I want to play games on the same fancy lg tv I use with my consoles. I just checked and it does not appear to have displayport.

Does AMD not support Display Port? I'm not an expert on this, but that sounds to me like the superior technology.

		TVs don't support displayport, so it makes Linux PCs like the Steam Machine inferior console replacements if you want high refresh rates. A lot of TVs now support 4K/120hz with VRR, the PS5 and Xbox Series X also support those modes. (Some games support 120, but it's also used to present a 40hz image in a 120hz container to improve input latency for games that can't hit 60 at high graphics quality.)
