When I press this button, the viewport temporarily turns black, showing only a small corner of the scene in the top-left. Then everything displays normally. This literally happens when switching modes, and it only occurs during mode changes.

Explain how DLSS works. From my understanding, I should render at a lower resolution and then upscale it to 2K or 4K, while keeping the image sharp and not blurry, especially if we are talking about DLSS 4.5.

Right now, I don’t fully understand it. I tried using DLSS, but rendering actually became slower than without it.

I need a clear explanation or a video showing how to use it properly.

In the imager node, `P_UPSAMPLE_SOURCE_PERCENTAGE` determines the "source" pixel percentage per side.

Say you have a viewport resolution of 1024x512, with 66 % configuration, the render engine uses 682x341 film buffer internally.

Note that each upscaler backend can have its limitation on the upscaling capability. For the current DLSS we use, if it's set at/below 25%, we will fall back to linearly upscaling.

As for the DLSS swapper, we do not support other versions of DLSS by swapping the dll.
