Don't install.
 
Stutters, FPS way down-from 60 to less than 30 now. I reinstalled 1.28 from 1.29. Will try 1.27 now.
 
Are there some things from earlier versions that remain and keep performance poor despite going back to an earlier version? If so how would one get back to a working version?

Ah nice to see PX1 opening up on my secondary monitor now which is where I like to keep it.
Also nice to see it opening up to my last loaded profile as well. At least the three fans are now showing spinning appropriately where I had set them.

Temperature Hysteresis still broken, setting is completely ignored

Cool GTX
 
Did you put the fans in the "stair-step" speed control - I believe currently that is the only way to get hysteresis to work

Nope, this is my curve:

 
In my case it completely ignores the value, causing the fans to constantly spin up and down between 59-60°C during medium usage, whereas they are supposed to keep spinning until cooled to 50°C with the settings I entered.
 
It does seem like hysteresis works in step mode as you suggested. I believe it's because step mode is applied at the software level, whereas slope mode is applied at the firmware level. I think it would be best if X1 enforced software-level control whenever hysteresis is greater than 0 (regardless of graph mode) in order to prevent any confusion.

Works fine with 970 here. Much more stable than usual too.

I am having an issue where the bios updates (fastboot disabled along with CSM) and upon powering off my PC (not restarting) and powering back on, my the fan on the graphics cards runs at 3000rpm (EVGA FTW 3 3080 ti Hybrid).  It will not stop unless I reinstall the bios, however, this cycle repeats itself if I power down/power on my PC.  Current bios is 94.02.71.00.C8.  Only the fan on the card runs at 100%.  I am on Windows 10 Build 19041, UEFI Bios, Asus z370-G Gaming, CPU 8700K, 32GB Ram 3700Mhz.  Any assistance anyone can provide to stop this would be greatly appreciated.  Thanks!

You should contact EVGA about this, you explained it better than the email I sent to them, maybe they will fix it one day.

Finally... This has allowed the FTW3 Ultra LED setting to save. Love it.. :)

True this. I installed 1.3 last night and my game fps dropped. Forza 5 is unplayable. Went back to 1.2.9 and it’s working better. Might try an earlier version.

Unless I'm missing something it appears the old tab that was at the top of the GUI is still there (invisible) because I can't place the window at the very top of the screen without it being auto positioned down to compensate for a GUI tab that is no longer visible.

I recently swapped back to EVGA Precision X after purchasing a 3090. However, I am having a hell of a time undervolting it. The app is acting very erratic.. Why does the clock offset (red line) go crazy?
 
The second thing is when I hit "apply" and close the voltage curve window. The primary window shows the second image which doesnt match the voltage curve window. Thoughts?

They are displaying the same thing but in different ways. I think the primary window is supposed to be closer to the "true" curve that you will see the card following, aggregating everything going on in the VF curve window.
 
For best results, first zoom in as far as possible on the VF curve window while working. I find this avoids any unwanted drift in the curve points when saving. I also prefer mode 2 for the red offset curve, at it seems to display things in a more intuitive way.
 
If undervolting, you'll want to select all the points above your chosen voltage and drag them down to at least -200MHz. You can't go too far here, this just keeps the card from boosting above your target voltage at lower temperatures.
 
Then, set your target offset at your desired undervolt. Again, zoom as much as needed to get the desired value. Just keep in mind that the 30 series speed bins are 15MHz wide, even though the software allows you to select 1MHz steps.
 
Below your target voltage, you can then select all points and use arrow keys to reset the offset to zero. Optionally, you can manually smooth the curve leading up to your target voltage, in case your card ever drops below the target voltage under load. I prefer this, as the VF curve window will otherwise apply visual (display only) auto-smoothing to abrupt changes in clock offset, which can obfuscate the final curve.

this is junk. impossible to use VF curve tuning. the secondary window after you select a point, the next point you select, bumps the freq to 2.1ghz above...
the primary window is too small to select VF curve point by point..
msi ab is way ahead.

Not sure what this is referring to. If you have multiple points selected, they will all assume the offset of the most recently selected point. You need to deselect points if that isn't the intention. I don't recall AB being much different here.

i have PX1 uninstalled
but firstly, the secondary VF screen runs at half fps or something, super jerky to use

Haven't noticed this.
 

kim666
In ab, i  usually pull offsets on 3 points of the curve which i found my gpu settles around during different type of loads. I click apply and the curve looks what i intended.

All with the same offset?
 

kim666
in PX1, when i try to do the same method and applied, the resulting curve shows only 3 points as offset, very confusing.

If I'm understanding correctly, you are applying an offset to only three points...so only those three points are shown with an offset. This seems like a logical way for the software to behave, and indeed the expected behavior. AB may appear to be doing something different, but in actuality I suspect it is doing the same thing.
 

kim666
You can have 1950@943mv and the next point shows 1800@950mv

Yes. Because you didn't apply an offset to the next point. The curve does not auto-smooth.
 

kim666
But also the 2nd and 3rd points showed an extra 100mhz offset. Say i selected 1950@943mv in ab as 2nd offset, px1 second screen shows me 2150@943mv

You're confusing me with your mixed use of clock speeds and the word "offset".
 
When using the VF curve in any program, you are applying a relative offset (e.g. +100Mhz). You cannot expect for that to result in a specific clock speed. GPU Boost automatically adjusts the entire voltage curve based on temperature and other factors, which means that you do not have direct control over the final core clock. The clock frequency scale should generally be ignored, since it will change from when the card is idle versus under load.

The VF setting screen is just janky to navigate, not sure why but my mouse seem to drop fps  on it, so often i mis-click the next dot and have to readjust, i cant even use tab to navigate. I thought AB was bad, but this is worse, and PX1 even has a larger VF screen!

Yeah, I don't have this issue at all.

This is how my AB VF setup looks like
On PX1, it will be only 3 peaks. 
From my use, i will say ab VF screen is more indicative of how the gp moves along the VF curve on a game moment to moment load.
 
PX1 could just be a display issue, but AB makes more sense to users.

It's actually not indicative of how the GPU boosts at all. Since you've only applied an offset at three points, the card is going to follow the default curve, and only use your offset at those three points. Therefore, the three peaks is a more accurate representation of the final curve.
 

kim666
As for the last part, i cant demostrate without PX1 now, perhaps you can try it out. Just select 2 points and hit apply, the 2nd point will somehow adds a huge offset. It is just poor indication to use.

If you select more than one point in PX1, all the selected points will assume the offset of the last selected point. I agree that this behavior is annoying, but it really isn't difficult to work around by simply adjusting the offset of each point individually (which is the whole reason you'd use a VF curve to begin with).

Upgrade to 1.3.0.0 lost FPS functionality within HWM for me and subsequently OSD as well
