The original source is clearer:

The launch version of PSSR framed almost the entire reconstruction pipeline as a single Color-Predicting Network. This gave the model a wide surface area for optimization, but it also implicitly asked the model to solve a number of disparate problems that already had efficient closed-form solutions. The talk will show how that generality became a cost, and how the upgrade walked much of it back: restoring explicit closed-form solutions where possible and focusing the model on the pattern recognition it is best suited for. The result improved visual quality and temporal stability while reducing runtime, memory, and training cost by giving the model less to do, not more.

So basically, they treated the whole render process as frame-in frame-out predictions. But by using traditional rendering techniques instead of pure ML the whole system gets faster and better (no surprise to me on that).

Games expect 3x upscaling now to meet performance targets, and ML requires exponentially more data to train a geberal model and test PSSR on a game — that’s the GPU month thing, if I had 30 GPUs it would take 1 day to train 1GPU month (ish — depends on gpu/etc).

The 540p thing is the training goes 4K -> downsample to 1080p -> downscale to 540p as an autencoder (model that tries to predict original input from progressively downscaled/bottle necked layers, with the idea it learns the best representation this way — not actually true though, not relevant here though).

The new model does the same ML but finishes with traditional compositing. That is to say, do you need an ML model to blend 50% blue onto yellow? No, you can use simple math and your ML can focus on the harder bits. So this all works faster and better with HDR. So now less work is done on that and more work is spent on upscaling.

The new model is also more deterministic, so it won’t hallucinate artifacts or turn your main character into a blond instagram model like NVidia DLSS.

Tl;dr, by replacing ML with traditional rendering you do less work, it’s faster to train and cheaper, and it does a better job overall.

Just scrape all the seeds into a mortar and pestle, grind them, throw the beans in some alcohol (rum, bourbon style Canadian whiskey, sherry), soak then leave them in a sugar bowl and save the sugar.

Now take the vanilla bean paste from your pestle and put it directly in my mouth.

I guess, but at least at home you don’t have to deal with limited devices to check the internet and esims/limited text message or calling availability

This has always been true

Do not share on social media you’ll be away on a trip, and only share your photos after you’re back

I was told this to prevent thefts, but this scam is just an even bigger variation on that (it still seems crazy people broadcast their images and locations publicly in near real time)

Excuse me, I didn’t give consent for you to put that cookie on my computer!

I keep seeing this content that’s “men are so stupid and inferior and awful” and it’s grating on me.

Like, yes, there’s definitely a strong toxic subset of men, but most of use are just… normal?

I’m in my mid 30s, when the women aren’t around we’re mostly talking about kids (those who have them), hockey, finances, house stuff, and weird health issues. Depending on the group, how stupid politics/government shit is lately.

I don’t know. It feels like the toxicity that came for incels is coming at women hard these last few years. Reddit really pushes this stuff lately.
