Raytracing slows gaming?????

[frimdent]

I read on Wikipedia that Ray tracing isn't ideal for gaming but movies and pictures due to the time it takes to produce a ray traced scene.does the Nvidia rtx cards over come this issue?

Real time ray tracing is simply very computationally intensive.
The upcoming releases from Nvidia are supposed to be good enough to do it.

We shall have to wait and see.

I am in for shopping one of the new RTX cards (still using a GTX970 in my 8700k rig and playing on 1440p/144hz G-sync). Its ok but not ideal, I just hit 60fps with my ideal graphic settings on most games and in some I barley reach it). So, when I built my new PC in December I intentionally opted against buying a 10series Nvida (back then due to high prices and the fact that I usually always skip one generation).

Anyway, I really following every little piece of information in regards to the RTX launch and performance leaks. Here a few thoughts:

1. Nvidia researched this technology for 10 years. They could have launched it last year, they could launched it next year, but they decided to launch it this year. Considering that they skipped one year with new GeForce releases shows me that they finally got it to a point where it will make an impact on the graphics market. It was not ready last year, otherwise we would have seen it (also has to do with availability and cost for GDDR6).

2. Nvidia is doing pretty well as a company overall. So there is no desperate financial need to throw a product on the market that is not ready yet.

3. Nvidia is very well aware that most players want to play games at 60fps+, and they know if they can't deliver this experience with the new technology that their loyal customer base would get a little upset

4. Price: yeah it sucks, but there is a lot of factors to consider. GDDR6 RAM, second largest chip ever build (that costs extra money), 12nn technology (gives lower yield than 14nm), new import duties on some electrical components, and R&D that was invested over the last 10 years into Tensor and Ray Tracing. I don't love the high price, but I understand their pricing to some degree. Don't get me wrong, I still would prefer to pay $600 for a RTX2080.

5. Will Ray Tracing make gaming slower? Probably yes, but I speculate that the technology is good enough to deliver 60fps at least in 1080p and 1440p. As soon that there will be optimized driver and game developer played around with that technology it will get much better than demos shown at the GamesCon. Ray Tracing will make games significantly better, but if you play online competitively and you need 144fps, Ray Tracing might not be for you.

6. Don't forget, if you play a game that uses the RTX chip for ray tracing to create the soft shadows or reflections (or both), the CUDA cores have a lot of extra resources for other stuff.

7. The same will most likely be true for the new AI AA that the tensor core is supposed to do. If that turns out to look nice and game developers integrate it into more games, not doing AA with the CUDA cores will open up HUGE resources. Just play a game and turn off all AA and see how that affects your FPS.

This is all just speculation, and it could come better or worse. But I just really think that Nvida wouldn't throw a product on the market that does not deliver. Nvida can't just live from preorders....

Just be patient and wait until mid-September. Read the reviews.

This all looks like I am very optimistic. Yeah, I don't have any reason not to be optimistic. But based on this I will NOT go ahead and pre-order a RTX without reading at least a couple of reviews when they come out.

I hope that helps.

I suspect it will be a few generations before GPUs can do real time ray tracing well enough to not have a large impact on performance. But its good Nvidia are starting now, as it needs to be developed and optimized in games first.

We saw similar trends with T&L, Physx, Tessellation etc.

Okay thanks bunch
