Do the linux drivers also suffer from the power spikes the windows drivers have for vega64?

Originally posted by Brisse View PostI kind of understand why they went with 35-90hz since this model came out before AMD introduced LFC in their driver, but now that LFC is a thing, it definitely runs better at 120 or 144hz. Also, BluRay's @ 23.976fps doesn't sync well at 90hz but will sync perfectly at 120/144hz.
For BluRays FreeSync might also be interesting. Using Windows, mpv already works with FreeSync.
BTW: While I don't play under Linux, I use a custom EDID there too. Simple reason: default mode in the EDID is 60 Hz and many Wayland compositors don't allow switching modes yet, so I have an EDID with the 144 Hz mode.

Yep, I've always been running mine at 56-144

Freesync/Adaptive Sync monitors define their dynamic refresh rate range in the EDID. It's then up to the graphics driver to respect these limitations.
Funny thing is that the range can be modified in the EDID and as long as you put in reasonable numbers it might work. For example, my MG279Q officially supports Freesync between 35-90hz, but I prefer to run it at 44-120hz. 57-144hz will also work. LFC takes care of the lower limit and duplicate frames up to three times, so the actual range if running 44-120hz is 44/3 = 14.7 - 120fps.

No, I've done it on Windows using CRU. I hope something similar will be possible on GNU/Linux once Freesync gets properly implemented.

Do you modify this in Linux?
I read about an tool CRU for Windows but don't know if such thing exists for Linux.
