Ratchet & Clank technical analysis *spawn

+ on original presets

so on Fidelity Mode in NXG analysis the 3080 was outperforming the PS5 on top of having a more expensive RT reflection than the PS5 on top of an already questionable on how the Game handles DRS (From Nixxes quotes) for the GPU to be fully utilized at the highest res possible

an Original preset would make this easier to avoid these skewed results to get published

we already got ppl "PS5 = 3080" due to this confusion . so you would need a 3090 (which is only +10% over the 3080 in average & typically 2x perf of the PS5) to 4080 to have any meaningful gap on the PS5 which is crazy

so it would be either a VERY horribly unoptimized published port by Nixxes or the Analysis is completely wrong

It's obviously completely wrong. I can get near double the PS5's performance on the 4070ti at PS5 matched settings (so way more at settings properly optimised for the Ada architecture) and the 4070ti is only about 30% faster than the 3080 in this game.
 
What happens if you just toggle off Reflex currently in the option menu?

Benchmarking with Reflex on always had a caveat in that while Reflex lowers input lag it can actually drop performance.

Should note that I missed the detail in the driver notes - Nvidia specifically refers to Directstorage performance in R&C with Reflex enabled.

Nvidia open issues said:
  • [Ratchet & Clank: Rift Apart] Game may display fluctuations in frame rate when using Reflex with DirectStorage [4212649]

I don't use reflex in this game as it has a slight performance hit, but DS still has a significant performance hit all the same, with or without it enabled. So no guarantee this next driver update will actually 'fix' the issue of DS causing GPU drops in general.

The NVIDIA rep specifically quoted this post though:

No fix for Ratchet & Clank DirectStorage issue.

That's a shame.
To which he replied that there is a fix. The implication is that this is a separate issue from DS with Reflex and that they will fix it in the next driver update. It could also mean just DS with Reflex though. He was asked to clarify but I don't think he's answered.
 
Certainly Reflex has a nasty performance hit with DS enabled. I just tested this in one area and had frame rate swing from ~80 to the low-mid 60's in a repeatable sequence with Reflex on while turning it off increased those lows by 10fps. That's without even having to reset the game. I didnt test much just now without DS (time constrained) so it wasnt clear whether performance was better again that the DS on/Reflex off results.
 
From the release notes

  • Visual improvements to some ray-traced reflections and ray-traced shadows
Will have to check that out!!

I wonder if these are more artistic changes where the RT effects have altered a scene is a way that was not intended by the artists? Do you have a save file at this point by any chance to see if it it's any different now?

LOD bias bug after fresh boot...fixed! Well, mostly.

As you can see, no difference. And it's just not a case of the DLSS reset now still sticking with the wrong bias, as you can see here from previous patch to this one (you'll have to zoom in for the boot details but then it becomes readily apparent).

(Also ensured I wasn't forcing a negative lodbias through nvinspector before these tests)

The 'mostly' part? Still has the mode-switching ballooning your vram by ~1GB. So on a 12GB card if you play around with DLSS settings, even going from fixed to dynamic res, VH textures will start to choke your card until you reload. So the previous recommendation to dial in your settings and then don't play with them after a reboot still stands.

But no need for lodbias hacks or dlss resetting after loading anymore.

Also further testing, the water caustics issue has not been fixed yet.

Awesome news! I Assume no significant performance impact that you've noticed?

Shame about the water caustic. I'm wondering if it's less a bug and more a deliberate implementation decision. Perhaps like AMD RT it wasn't working properly so they chose to leave it out at least for now. There is a water ripple texture applied so they've clearly gone to some effort to put something there in its place.

No additional performance hit from compared to resetting the lod bias in the previous patch, but there is a hit vs. the wrong lod before as you might assume, simply because it's drawing in more.

The water ripple texture exists in the PS5 version too, this is just missing the additional wave effect.
 
Texture streaming issue is back.. and now I'm having performance issues where I wasn't before. Game is stuttery now.

*Sigh*


Edit: Ok, it was my mistake. There definitely WAS issues texture streaming issues... but I forgot that I updated my BIOS and my RAM wasn't running XMP and my CPU OC wasn't there.. lol 😄

There's no texture streaming issues anymore, and the performance is where it should be again.. my bad lol

The gap between AMD and NVIDIA in RT performance in Ratchet and Clank is significant, at 1440p native, the 3080Ti is 66% faster than 6900XT, at 2160p, it's 50% faster. So it shrinks with resolution. The 4070Ti is also 40% faster than 7900XT at both 1440p and 2160p.

Not unexpected at the max RT settings but a comparison at console level RT would be really interesting (relative to no RT).
