Elon Musk is a piece of shit.

Test

It’s hard to believe this MR head been open for over 3 years. I don’t understand why they didn’t release it in 46 as an experimental feature. I’ve begrudgingly resorted to using kde again just for this feature.

Another release and no vrr, big surprise.

I’ve got 3 displays. I just noticed something interesting; if I apply my settings in LACT I notice some flicker, if I then logout of my gnome session and relogin it seems fine, no flickering yet. I’ll do some more testing.

I just tested memtest_vulkan on linux, everything default but set Mclk to 1300, and it passed. But, there was still some flickering, not non-stop, but every once in a while I would get a flicker.

Basically no increase with default voltage either. If I bump mclk +10 it starts to flicker. Set it back to 1250 and no more flickering. I will have to test that on windows when I get some time.

Fedora 39 + Mesa 23.3.2. Yea, the mclk is stable at 2500mhz default and even increasing it say 50mhz seems to cause flickering, that will sometimes go away then come back. Adrenaline version is latest, 23.12.1.

Windows:

mclk: 2650
clk: 3000
voltage: 1020
power limit: 15%

Linux LACT settings:

mclk: 1325
clk: 3000
voltage offset: -80
power limit: 333w

It’s a powercolor hellhound 7900xt.

Performance is night and day now, thanks for the hard work
