    There is minimum raytracing throughput required to have reasonable IQ and fps at same time. That means you need some, not so small transistor investment.
    My guess is that we need ~6B transistors invested just into RT to get good enough results. That's extra cost for GPU which needs to remain competitive on rasterization side of things.

    I am really not sure when we are to see mainstream priced GPUs with 18~20B transistors.

    RTX 2070 has 11B transistors, GTX 1070 has 7B, so lets say transistor number increases by 1.5x every 2 yrs - so about 4 yrs from now and 2 GPU generations from now to hit about 20B+ transistors.

    At 1080p... how many of us here use 1080p?

    Vega 64 is as fast if not faster in BFV then 2070 obviously no Ray Tracing.

    But on a 2070, the Ray Tracing is way too slow.

    Thing with this tech is. It's the first Installment. Not worth buying until a couple of generations and needs to mature.

    But some may still want it for other single player games etc.

    Ha ha...exactly. This cycle is repeated anew.

    Only issue is that 2070 is not exactly at mainstream price. In 4 years, we are likely going to be still at 7nm as AMD stated that it is here to stay for longer. (And that's probably why they invested early into 7nm.)

    So, question is: Will GPU w/ 20B transistors on 7nm cost around same as mainstream today (inflation included). I kind of think we may need 5nm or MCM to get cost under control.
    But even if it is not priced in way that we could call it mainstream, it would be much more affordable and make more sense.
    = = = =
    Side note, I knew that performance would tank this way from math provided by developers of new Metro. And I was like:
    "Let's bring topic of 720p benchmarking. Maybe even troll with running 720p CPU benchmarks on games with raytracing."

    Am I reading those graphs wrong, or is Medium DXR performing better on the 2080 than on the 2080 Ti?

    I've not looked into all the details, but my first reaction is that I'd be surprised if we're still on 7nm in 4 yrs. If they stay on 7nm for a long time, then I guess the price of manufacture of the silicon will become cheaper as they increase yields through fine tuning of the manufacturing process, but how much it would decrease I do not know, and whether or not that would offset the increased costs of a larger die to accommodate those 20B transistors. My gut reaction is that a smaller node would be needed to keep costs under control, as you've mentioned. Who knows, but I'm not buying a Turing GPU, the next gen is probably what I'll go with, because I'm certainly not gonna wait 4 yrs from now for a GPU upgrade!

    I don't care how pathetic it is, I'm just glad it's finally been started. We've been relying entirely on rasterization for far too long. Without ray tracing, games will remain in the uncanny valley of weirdness for the rest of our lives.

    Im ok with 4K/30fps, i never puked while playing exclsuive Sony games on old PS3 and new PS4Pro Uncharted, Killzone, inFamous and all the rest are 30fps and thats fine by me, i play with gamepad anyway.
    In my case I use OLED TV as my monitor, so even if i play in 1080p /60 it actually look great, the internal upscaling is of high quality and in any case 1080p on 4k screen is just 4 pixels doubling so look good.
    So i have a choise, 1080p/60 or 4k/30 or if the game has internal scaler then maybe something in between scaled internally to 4k

    Tbh, I feel the performance-loss with RTX on is much better than I thought it'd be.

    Of-course, this technology is something we'll appreciate more in a few more generations of hardware.

    Dice has already stated that Medium settings on their RTX currently is bugged, so don't look at medium :)

    Finally 4K Ultra with DRX Low works fine above 50FPS with 2080Ti but no SLI at all. I also tried SWBF2 SLI profile for DX11 also and it works fine too well above 100FPS but no DXR at all in DX11.

    Seems obvious that they need more dedicated RTX cores on the die for this to work properly. There is just not enough space on the die.

    Why wouldn't they sell a daughter card with only RTX cores instead of trying to do it all on one PCB? That way the price of the GTX card are still a good value and if you want ray tracing you buy a 2nd card.

    Actually a cool idea. Practically, add in cards seem to be declining in popularity, Physix never kicked off with dedicated cards, (W)LAN connectivity is on every mainboard these days, as well as sound chips. It would make most sense in terms of available market customers, some just buying the GPU part and call it a day.
    Also I agree, as it seems they either need to be way better at doing RTX (software wise), or they need more die space for it... the second part is probably more of an issue here since bigger dies are always more troublesome than a better algorithm / software.

    I'm also wondering, if at any point DLSS will work together with ray tracing, which could help produce more than 30fps on 4K resolutions with current cards, for instance, and possibly stable and playable stutter free 60fps on 1440p. If they can do that at some point, I could imagine that the next iteration of RT cores can really help bring RTX to 4K resolutions (maybe 1440p rendered and then upscaled / supersampled via Nvidia's supercomputers via DLSS).

    Theoretically they could calculate raytraced reflections at reduced resolutions, then put it through DLSS and afterwards do blending composition to existing scene (or whatever method they use merge raytraced data with rasterized).

    This way only raytraced information gets DLSS threatment for greatly improved performance and removal of some artifacts... keeping rasterized image cleaner.

    It should be noted that only 1.31% are gaming in 4k. Those that play at 1440p are 3.52% of the population, which leaves the the vast majority of those not running 1080p actually using a lower resolution than a higher one by a lot.

    Some guy the other day was bragging on global chat about getting 120fps with all settings on Epic in Ark: Extinction on a GTX 1080, which of course after a few questions we discovered he was running 720p.

    I didnt know DX12 has to be enabled to use RTX.
