Looks like I've been missing all the fun!

Pics of the new home for my 6900xt lol.
I can highly recommend the O11D EVO as the results on my new loop are amazing.

Looks very nice mate, congrats!
Curious to know what clock speed/voltage settings you run with the 293W default power limit at +15%?

Been playing Guardians of the galaxy since it hit game pass at these settings:
Update, these are better. Had a boot out to desktop after 2h+ with the higher clocks.

Have you verified that the GPU voltage used is actually changing from 1.175v to 1.075v? Because typically once you go over 2600Mhz max core clock, reducing the voltage slider (which applies a offset to the voltage-frequency curve) does nothing.
I find (with several XTXH) that if I use 2600Mhz or higher, then I need to reduce the voltage using MPT to see actual verified voltage levels (monitored via HWINFO64 voltage value) reduce from the default 1.2v. If I use 2599Mhz or lower, voltage reductions using the slider in RS works as expected.

Either change it to brown or change the others to the black

Just for info I find that Global sometimes 'loses' the settings, but if you create a game profile it stays as it should
These are my 'safe' ones atm for TD2, been having some issues with it but not with other games (think I need a full wipe, waiting for the new AMD drivers to drop). Have MPT set to 347W and 2200 Fclk those are the only changes;

Just run a TS extreme @ 2550/2650, 1075mv set. According to Hwinfo 1048mv (VDDCR_GPU), 1054mv (VDDCR_SOC) was the peak. https://www.3dmark.com/spy/26952552I was going to say, find it hard to believe the first set were stable.

With 2499/2599, 1075mv set. 1019mv(VDDCR_GPU), 1061mv (VDDCR_SOC) was the peak. https://www.3dmark.com/spy/26952714
With 2499/2599, 1060mv set. 1014mv(VDDCR_GPU), 1062mv (VDDCR_SOC) was the peak. https://www.3dmark.com/spy/26952860 (winner)
With 2550/2650, 1060mv set. 1024mv(VDDCR_GPU), 1061mv (VDDCR_SOC) was the peak. https://www.3dmark.com/spy/26952957
With 2499/2599, 1175mv set. 1091mv(VDDCR_GPU), 0844mv (VDDCR_SOC) was the peak. https://www.3dmark.com/spy/26953054 (fell off a cliff)
With 2499/2599, 1040mv set. Driver crash.
I've seen the behavior of the voltage doing what it likes in the past, like you said beyond a certain point the card just pulls what it needs. It seems to of changed in behavior from older drivers as I'd looked into this before and seen the higher voltages been reported in HWinfo. Looks like my settings are the sweet spot for a 293w power limit on water.

Good testing. Those temps will definitely help keep the power draw a bit lower too.

Just ran Guardians and that pulled 1111mv with 1060mv set @2650Mhz. So 2499/2599 might be the magic numbers for the efficiency sweet spot. I'll do a few hours and run HWinfo in the background to see what numbers I get.

New driver is out with RSR etc over in the AMD driver thread.
Didnt realise we had an AMD rep either.

Seem to be very slightly better than the last driver in timespy.

VIK is good people.
@Duckwave did you ever get your Warzone issues in Caldera sorted with the 6900XT? I just picked one up at the weekend and having similar problems I think, nice high FPS the majority of the time 180+ but jarring drops to 130-140 when traversing the map or entering more busy areas. I'm paired with a 5900x and 32GB 3800 C16 DDR4, 1440p mostly low/competitive settings.

Here's how it runs for me at 1440P low settings on a 5950X+6900 XT.
