6144x3216 pixels is definitely much higher than the native resolution of the Quest3.

Do you understand what is barrel distortion correction?   You need always to draw more pixels that panel native resolution to have 1:1 resolution.

You have to draw more pixels to account for barrel distortion correction algorytm. With that resolution in VD (godlike)you are not super sampling and not undersampling (in case choosing preset bellow godlike). When you undersampling and use Qualcomm SGSR on quest chip it upscales the  image to the native quest resolution which is much higher than a panel physical resolution since barrel distortion correction needs more pixels to work.

That's the entire point.

It is a form of super-sampling in the sense that it renders more pixels than the native resolution. The Quest3 upscaler only works on lower resolutions ("High" and lower in VD) and it only upscales to the native panel resolution (2064 × 2208). And the final image looks pretty awful anyway, so I never use it.

Aha. Process Lasso has something called Efficiency mode and that was turned off by default for il2series.exe. Efficiency mode apparently means that the process runs on the part of the CPU that is most efficient but has less processing power.

It wasn't until I specifically gave il2series.exe exclusive access to CCD0 that I got this enormous performance boost.

Glad you're getting a performance boost with Process Lasso. I just tested the same and am seeing a small gain over the default core-parking method, even outside of VR:

One additional thing you can do with Process Lasso is force Track IR to use one of the cores that is not being used by the game. I've been doing that for years to reduce stuttering.

From 50 to 70+ fps in the 1% percentile range! That is quite insane, and I can tell you that it is night and day in VR.

Setting up Process Lasso so that these settings don't apply when you're not running Il-2 is very easy. You simply go to File->Config profile->Create config profile, and then add the CPU affinity settings while that profile is active. You then switch back to the old profile and go to the File->Config-profile->Config profile switcher menu to setup a profile switch on il2series.exe

It's not a super sampling is barley enough to render at native panel resolution with right geometry. Going above that would be super sampling. Quest upscaler can work on all present resolution if  you choose to enable it.

Dude, I know what resolution I am rendering because the debug screen tells me so. Whether you want to call it super-sampling or not is irrelevant. The Quest upscaler is made for native Quest games and makes no difference on Ultra and Godlike. You can enable it but there is no difference in the image.

It's all technical terms and you just making it's  same thing, doesn't matter that you know your resolution. You are wrong that it's only for quest native games, ask guygodin VD developer if you want confirm that you are wrong. This discussion is over, I would not waste my time anymore. 

[reidarpeidar]

I am rendering 6144x3216 pixels, which was the initial claim you wanted to bicker about. The technical terms you later brought into the discussion don't matter.

Not, it's not ONLY for Quest games, I never said that, but that's obviously what it was made for. You are like that guy from Monty Python's Flying Circus:
