Pimax anomaly ( SU11)

@MasterCptn … All of that has been covered in this thread… It’s not a solution… And at least for me it’s only offered a small improvement… But to be honest I haven’t tried VR in MSFS for over 2 months so for all I know sim update 11 has fixed it

Thank you.
Are you saying that DLSS is the only solution?
Does it mean that models that worked before SU10, such as GTX and Radeon other than RTX, no longer work properly after that?
Also, it seems that there are many people who say that 3090 and 4090 do not improve, so I will ask questions elsewhere.
I have tried many times before, but I will try something other than TAA for the time being.
But anyway, if my assumption above is correct, this is not the solution.

I just did a test.
Again, the SU11 doesn’t bring any improvement.
I lowered the low end and render scale to 70, but the flickering persisted.
70 is a setting value that causes pain because the brain thinks that something is wrong with the eyes.
In other words, even minimal image quality remains deprived of a way to function properly.

Before SU10, I used custom image quality, set most items higher than middle, and was comfortable with TAA and a rendering scale of 100.

Unfortunately the SU11 didn’t bring any improvement.


I have noticed that when I use my Pimax 8kx at 90 Hz, the image flickers.

With 75 Hz all is well. I only use Normal field of view, not large.

is your 8kx the model with 2075 or 2076 in the serial number? 2075’s may have problems with running at 90hz. i’d contact pimax support about it, they might be able to give you a firmware which helps out.

Hi @tykey6 ,

Thanks for the heads up!
Indeed my 8kx serial no. begins with 2075. I will contact Pimax for a replacement firmware.

Mine is a PIMAX5K+, so the problem doesn’t occur in the first place, but I tried lowering the frequency just in case.
There was no improvement.
So far, I haven’t seen anyone other than you say they have no problems with the SU10.
Even if there is, we can only obtain fragmentary information.
For the time being, those who are working without any restrictions or deterioration can easily understand that giving out fragmentary information will not benefit anyone. Full information would be more meaningful in this place.
In any case, there is currently no clear way for anyone to restore the environment that SU10 has taken away.
And there is no announcement of what preparations can be made to get it back.
There are reports and videos that say that some things work, but that they don’t actually work.
There is nothing to believe.
This is an absurd situation.
Of course, what should be solved is the people who forced SU10, and in order to save those who are swayed by uncertain information here, clear information from the management is the most important.

I did have a problem with SU10 and I posted on here about it. On Large fov i was getting flickering scenery, but as i usually use Normal not Large fov it didn’t bother me.

The other day I accidentally started the game at Large fov and it was ok, the only difference was I was now using the Beta. I don’t know if that made the difference but the game @ Large fov appeared ok to me.

Edit: the issue still remains on Large fov, just tested it again.

I got the 8KX 4 weeks ago (model with 2076 sn) and faced the same issue. Never tried it with 75hz or lower settings. Im running an i9 13900K with a RTX 4090 so i want to have best quality. Quality and FOV was great but with such a flickering it was impossible to fly.

Pimax Support official doesn‘t know of this problem and overall the support was so bad that i returned the Pimax.

Tomorrow i will get the Varjo Aero, lets see whether i‘ll have more luck with it.

None? It still does the occasional misposed frame for me…are you sure? Not even in a different scene?

i didn’t spot anything but i only flew for about 5 mins on Large. i’ll test it for longer and in different conditions later today and post here if i spot something that shouldn’t happen.

Edit: just tested it and indeed the problem still remains on Large fov, unsure why i thought it had gone :confused:

After receiving a replacement firmware from Pimax , I can now fly at 90 Hz with my 8kx. :grin:
Pimax responded really quick and sent me the new firmware file. :+1:

Narrowing the viewing angle to avoid bugs?
If so, it is not the original performance of PIMAX.

Unfortunately, there seems to be no mention of PIMAX in the next update either.
Some people say that if the operator had the right technology, it wouldn’t take long to deal with this kind of problem, but it seems that the operator still can’t do it.

Of course the issue is still present, I have done a Zendesk report on it and upvoted the issue as well.

Now that you made this matter; in this thread, the Pimax Anamoly (11) I was the first and only one to mention that TAA was the issue and that if you switch to Nvidia DLSS and choose quality, performance or ultra performance, the flickering goes away.

Further findings after my first comment:
Runtime needs to be PimaxXR.
You also have to be very specific in Pitool Client, device settings: smart smoothing on and compulsive smooth set to 1/2. Do not use other functions. Parallell projection off, fixed foveated rendering off, hidden area mask off. MSFS VR reprojection off.

The settings I’ve activated in Pitool client, MSFS specific settings, I’m at 75hz, native, FOV large, render quality 1, Smart smoothing on, compulsive smoothing 1/2. If you go to compulsive smooth1/3, flickers start again. What is not on this list of Pitool functions is turned off. (backlight and contrast is of course active)

MSFS VR graphics are maxed out with these settings with no flickers.as I have a 4090 OC. The FPS is locked to 37,5FPS in all scenarios.

Hope this helps.

Thank you for the extremely detailed information.
I don’t have the environment to test it, but some people may find this information useful.

My feeling is that canceling TAA is not the solution, but that the high level of drawing support capabilities of DLSS is the solution to the problem.
I think the important point here is whether DLSS is decisive, or whether the FPS that DLSS brings is decisive.
This is a bit meaningful information now that the new model of RADEON is about to be released, but above all, it contains the fundamental problem of whether it is a problem that can be solved by choosing anti-aliasing.

It is interesting to see the subtlety of the Forced Smooth settings on the PITOOL settings.
The need to turn off FFR is also a little interesting, but in terms of FPS, it should be more damage, so I think it’s not very predictable.
I’m letting go of my 3080ti right now and only have a reserve 1080ti (As a temporary refuge for replacement, the 1080TI with 11GB of VRAM was better than expected. Until this SU10 happened, there was no problem at all. However, considering the current information, the 3080ti But it seems that this problem has occurred.) so I don’t have DLSS so I can’t test it, but I think it’s useful information for some refugees. For me, it’s a vexing question, what should I do with my next GPU?
Regarding this, it seems that there is no choice but to lower the altitude and see the situation.

Some say that FSR3 is an illusion, and others say that ray tracing will make a big difference as before.
There is also information that DLSS introduces disturbances to aircraft instrument displays on MSFS.
To top it all off, for us, this wide-angle VR issue adds to the complexity.

I bought some planes on sale.
I’m not going to try it outside of wide-angle VR.
Because it’s something special.
I hope this won’t be your last investment in MSFS.

Unfortunately, this method is also not universal according to information provided by other 4090 users.
Currently, there are no measures that users can take with peace of mind.
It’s been a long time since Su10.
I feel that it is insane that the management side has not announced anything for the time being.

How is your latest situation?
I’m using PIMAX OPENXR, and with the same image quality settings as before, I’m facing a few seconds of normal display, and more frequent flickering than last month, and a repetition of these two conditions.
With all anti-aliasing turned off, the frequency of flickering has decreased, but it always occurs once every ten or so seconds.
In the first place, without anti-aliasing, the health of the eyes will be in a severe state.
