Same problem with my FTW3.
 
I tried many different manual overclocks, and default speeds, and often the card would not boost, temps in the 40s C, and game performance worse than my old 980s.

After playing around all day I found this:
 
#1 Shutdown your pc.
#2 Unplug psu from wall.
#3 Press & hold tower power on button for 30 seconds.
#4 Plug psu back into wall.
#5 Start pc.
#6 Start XOC. XOC should update the mcu's on the card with new firmware that should resolve the problem.
 
From 
 
And that appears to have fixed it for now. It now holds the boost without fluctuation, temperatures high 50s.
 
Particularly interesting is that the problem first manifest as not holding the boost -- however in Fortnite while alt-tabbed with the game up in the background (while running at 400+ fps), the boost was held. Then, when going back into the game, the game would dip and drop boost. It got worse (?) over time, and noticed the same behavior in Overwatch and Black Ops 4. Got the the point where it was exactly as described by the OP.
 
I will update after more gaming tonight, and send a FireStrike run or whatever other logs if the problem reoccurs.

Your talking Precision X1 and not XOC right?

Ok giving that a try. It seems to have cleared out my fan curve profile I worked so hard on ugh lol.
Will see if I can get it set back up like I had, probably tomorrow before I can really test it.

Yes, those steps worked for me using X1 0.3.3.3. 
I'll be booting later tonight to see if it's still resolved.

I get a low score in fire strike too. Not a big deal though as fire strike is a 1080p test. I don't game at 1080p. I game @ 4k. I'm #20 on the fire strike extreme graphics score list.

Nice, I'm #16 when ranked by my CPU/gpu combo

To compare do you have a link to Fire Strike?
Thanks

@d.burnette  do you have a Link to your Score?

I did not have latest version of 3d Mark and it would not update from the program, so had to get a new install.
Ran Firestrike again with a little better result.
I think my CPU/Ram is probably holding me back a bit. The card was boosting nicely during the run.

Soon as the Z390 Dark is available I will be getting my new build done, hopefully that will help.

Your rig spanks my rig. For now....

I would think it is low because of your CPU 4 Core -v- 6 Core.
Maybe 4 Cores is not cutting it well with RTX Graphics Cards.

Did you try the lock feature out in msi afterburner?

No, at least not yet. Would prefer just to stay with the one program - PX1, at least at this time.
Have not been able to game much since, will have some time tomorrow and see if it still does it. I know since I have gotten a MCU update and new firmware.
 
Thanks much for the info, and I may end up trying it yet!
 
 
 

I am throwing in the towel here.
For whatever reason, whilst this game worked just fine initially with my new 2080 Ti FTW3 Ultra, now the card can't run it.
 
I did complete sweep of the drivers with DDU, and a complete clean install of the latest Nvidia drivers.
 
No dice, not a change. Card runs at 1350 Mhz and performance is really,, really bad. I have played this particular game for probably the last year or so pretty much on a daily basis, and have never seen this. 
 
Really, really frustrated...
