Fair point. RT is a good generation ahead even though it's still a gen behind Nvidia. Shame it's doesn't work for cyberpunk.

Anything other than a 4090 on cyberpunk struggles.
Welcome! I have that saved on the desktop so if it ever gets an update or crash and resets I can just drag it back in although my cod hours have been 0 since Diablo came out

Clickbait for a 12 minute technical video on RT, i got to 6 minutes in of him rambling the technicalities of RT, he actually said 3 times at that point that he didn't want to go in to the technicalities of RT for this bite size video, and then said "anyway" and goes back to rambling mind numbing technicalities repeating the same thing in different ways over and over again.
Everything is about the 10 minute length Youtube algorithm so they can squeeze 16 15 second adverts in it (if you're watching it on a telly where no adblock exists) and make anything and everything unwatchable.
Now completely brain dead and frustrated i'm none the wiser as to the purpose of the video or the rumour.

This is the conclusion i came to, i wanted someone to explain it to me cos it was just a complete mess of rambling jargon that made no sense to me lol.

I'll try to get through the remaining 6 minutes to see if there is a point to it...

From what i can gather AMD have been R&D'ing a new way to calculate RT and there is a huge uplift in performance, but its all for the future, an unknown future.
A 12 minute video to say that, he calls what is a full CH5 documentary (once you've taken all the adverts and recaps out) a "bite size" video, this is why i unsubscribed from him, he rambles and rambles on just to fill 9 minutes of a 10 minute+ video because the Youtube algorithm doesn't promote anything that's less than 10 minutes long.

Eh? It works just fine on my 7900XTX at the same level of performance as my 3090 did
That's my point, as well as a last gen Nvidia card. It's can't match the 4090 or even 4080.
Problem is that few people can afford cards priced over £1,000.
The cost per frame on the 4090 is poor. You don't get 2x the performance of the RX 7900 XT, even assuming this card costs £800, which it doesn't, more like £700 (far better than the RTX 3090 TI price). If you did, the price might seem less ridiculous.
It's safe to say that the RTX 4090 TI is pretty unlikely to offer 2x the performance of the RX 7900 XT also.
You'd need a card that could offer 1% lows of ~160 to get double the performance, the 4090 doesn't come close.

Its literally the only game with RT I own (unless you count Hogwarts and thats broken for all users) and too many nvidia users are reporting issues with Hogwarts because their vram is is inadequate and thats more useful. The worship of the gods of RT is overdone.

A good rule of thumb that people sometimes forget, is to try to buy something that is equal or a bit better than the top card of the last generation (AMD or NVIDIA).
The RTX 4080 should've been the price competitive card to beat AMD's 7900 series cards, but presumably they just can't produce enough.
meanwhile, there's RTX 4070 TIs selling for £800 or more... This is clearly the card that Nvidia wants to sell to consumers / mass produce. Also the RTX 4070.
On the Nvidia side, lots of people seem to be thinking this whole generation is one to skip. There haven't been the necessary price reductions at the high end to make them sufficiently appealing.

When AMD and Nvidia initially placed their orders with TSMC for the chips there was a scarcity of supply from TSMC but that is no longer the case. Nvidia wanted to lower their production but TSMC did not let them out of the contract. There is supply for the silicon if it is needed and the ram is also low in price and available, if AMD or Nv they wanted to produce more cards then they easily could. The pandemic production constraints are not really an issue anymore.
Prices have dropped but not to the point where they are enticing the millions of gamers on 1060, 1650, 2060 to upgrade and yes many will skip this gen.

Simply put- BVH transversal is a way to help accelerate ray tracing by grouping objects together based on their location.
The RT system then uses this list to find objects in that area that will possibly come into contact with the approximate path of the ray (narrows down the search). If it's decided a ray will hit that boundary, it'll split that boundary and keep doing until it finds the primitive (poly) it actually intersects with.
Short: BVH transversal makes ray tracing faster. It basically makes an index for the lighting system so it can find where the rays hit faster than just raw dogging it.
Nvidia has hardware acceleration for this because BVH transversal is very computationally expensive, you need to generate this index based on whats currently on screen/where the camera is pointed. this changes often too making it harder.
AMD uses a different method using texture data instead, amds looking into implementing their own method of BVH transversal, and in some tests it increases performance by 1.5x.

Glad you put that into more plain english for us folk! Be interesting to see how this plays out then, it will be quite the jump in RT performance if they manage to implement it properly.

You did well as soon as I hear this bloke I want to fall asleep
I think they'd probably rather commit themselves to product refreshes / improvements, if they are going to spend on more capacity. They would make more money that way.
