Ratchet and Clank: Rift Apart RDNA 2 Ray Tracing

[shankly1985]

So I am watching DF video on this game and like them are blown away by just how good this game looks truly looks next gen. But its the Ray tracing part why I am creating this thread to talk about it.

I remember a thread on here I tried looking for it to post but was unable. Within that thread was talk about this games pre-release and how bad it was doing Ray tracing "Low Quality" Missing Reflection etc RDNA 2 in the console was talked about it being not strong enough etc

Fast forward to the games release and.... Everything that was slated as been improved 10 fold link below jumps you right to the RT part but I recommend you watch it all tbh

So what some people on here can take from this is do not slate something from pre-release until its out and reviewed.

Edit

This video was recorded before the 60fps RT performance patch also. DF will be doing another video for that mode.

checkerboarded RT at not quite 4K and not always 30FPS, the power

They is a RT 60fps mode that DF will be doing a video on soon.

Edit

Its not just RT though look at everything else that game is doing. Its a very good showcase for basically the consoles first true next gen title. Consoles improve even more over time.

Or the fact it got widely slated prompted the developer to put more effort in?

No I don't think that is the case. The slating was this forum, looking at YouTube comments from pre-release footage you do see people excited for the game no real complaint about RT

This forum wasn't the only place where people were critical of the low resolution reflections, etc.

IIRC they put out a post defending it as a trade off at the time.

I must admit I didn't go far to looking. I just remember in this forum the day that game was shown it got slated for the 30fps low frame rate and not so great RT reflections.

Its £450 for the console. Point me in the direction of a pc that comes close.

Plus to the quality that is on offer from this game.
No pc game released at the moment comes close the the level of detail this game is offering.

The bit where they zoom into a fly and it offers that much detail is mind blown.

These are the areas you see mostly pop in etc with all this now gone I rate these upgrades over a lot of improvements for next gen.

Reason being its stuff you actually notice while playing.

 

[shankly1985]

And the release version isn't perfect, there are still many areas that could be nitpicked when it comes to ray tracing even though yes it looks better than the first demo.

here is a quick example I put together in 2 minutes, this is a scene from early in the game.

I've drawn circles around 4 areas to discuss:

Red: Reflection on metal floor lacks detail from the leafs, despite the reflection being very close to the screen and a very small distance between the leafs and floor, the reflection is just a green blur

Blue: This gold metalic circular objects are reflected back as a black object on the floor. This is a ray tracing flaw. The gold metal object also reflects, so if you allow it's surface to reflect off the floor, part of it will reflect back to the metal circular object. This would create an infinite ray tracing reflection loop that would kill performance. To avoid this problem, it's color is changed to black so that nothing reflects back.

Purple: The poster's reflection is reduced enough in quality that none of the writing on the poster can be seen in the reflection

Green: None of the flowers are reflected on the floor, even though the metal beams behind the flower are reflected. It implies there was a design choice made to exclude the flowers from the BVH table to save performance (i guess reflections of Foliage is very performance intensive). This gives the reflection on the floor a fake look, because the flowers should partially block the beams from being able to reflect yet its as if the flower bed simply doesn't exist

Nit picked being the key word here.

You could do this with every game ever released tbh
What matters the most is in motion while sitting back and enjoying the game.
I am very suprised they managed to up the quality of Ray tracing while still adding in more detail.

 

[shankly1985]

Does not look like my cup of tea at all this game, however I will begrudgingly admit to being impressed with the reflections from that video.

Perhaps this could be one of the first PC games to actually have a decent RT implementation that looks better than 'unrealistic' raster?

Sadly I doubt Sony would release this series onto the PC.

 

[shankly1985]

Not bad for a console, but why is there so much blur as you get closer to the left and right edge of the screen?

Probably motion blur picture is taken from motion.

 

[shankly1985]

I dont think they can with current PC SSD tech can they? Doesn't this game utilise the drive in the PS5 to perform the loading when jumping between areas?

It's a very good question tbh right now in the PC current state I would say no with current SSDs
I think the game would require nvme drive

 

[shankly1985]

Yep, unless RTX IO shows up we won't see it on PC and even when RTX IO shows up, having your game's minimum spec required a RTx3000/RX6000 GPU and 5GB/s pcie4 Nvme drive is a recipe for failure, so few people have the hardware to run this game that they'd have poor sales and a whole lot of people complaining they want refunds

I believe Windows 11 being shown this month will be the release for Direct Storage

[shankly1985]

Cant wait till it's finally available and we can see a bit faster load times. I also hope Microsoft gives us quick resume I'd love that.

I can't see this ratchet and clank game on PC until closer to the end of this generation simply because the IO requirements can currently only be met by 1% or less than 1% of PC gamers and that figure will have to come much much higher before Sony considers it

Yeah totally most PC gamers are still rocking hard drives and first generation SSDs.

 

[shankly1985]

Really this nonsense again? We even have ps4 exclusives now on pc and equivalent gpus run them on par with a ps4 or ps4 pro. There is no such thing as magic fairy dusty console optimization.

Now why don't you put your pc components on members market? Tons of people will want to buy them and you can go play some irrelevant console kiddie game.

No they really is

The ps3 had 512mb shared ram

You try running GTA 5 on a pc with that much shared ram.

Console devs get extra out of the hardware because its simple one configuration for them all.

PC is much harder to optimise for because of the amount different hardware configuration available.

 

[shankly1985]

Indeed. That was only true for the ps3/xbox360 era since the architectures were very different.

But as expected, people are peddling the same old misinformation just like in most other areas.

Not true at all.
Next generation games for the console devs will squeeze more out of the hardware available to them than they could with pc.

I have always looked at pc being brute forced.
