It’s being worked on, but it’s not a simple feature so I don’t have an ETA.
As Andy noted in this comment on GitHub, DSC is already enabled and working at lower pixel clocks, but a more complicated hardware configuration is needed to support the extremely high pixel clocks needed to support 8K@60Hz or extremely high refresh rates at lower resolutions.
It’s very reassuring that it’s being worked on. Really looking forward to it!
Driver R535 Beta mentions this feature, so I’d presume it’s out now
Added support for driving very high pixel clock mode timings such as 8K @ 60Hz. Please see the “MaxOneHardwareHead” X11 ModeValidation token in the README for details.
Confirmed. FINALLY got their crap together and can run 5120x1440@240hz on 535. About time.
Also confirmed working :)
