Current Generation Games Analysis Technical Discussion [2020-2021] [XBSX|S, PS5, PC]

This is more or less an carefully optimized port. I would also guess, that it uses the same packaging as PC and no decompression via hardware just brute-force CPU usage. They are a small team and according to their games legacy, they don't have the necessary knowledge/manpower to optimize a game for every platform. Using RT in that title was just overkill without further optimization. RT is always expensive, even if it is not visible in every scene. We've seen this in Battlefield 5 where there was absolut no reflection in some levels, but the performance was still much worse than without RT. And Dice has the manpower and knowledge to optimize for something like this.

I guess smaller teams, will start to implement RT in their games, once it is not much more than a flag in the engine and already runs well optimized. Their might be exceptions but all in all it is currently much more work than the traditional way (that must also get implemented).

 

Agree with all but they are now not so small

 

You can tell that Bloober didn't spend much resources on the PS5 port, considering that Observer redux already has RT on the PS5.

 

AFAIK medium is much more demanding title than redux, anyway i think its the opposite removing RT makes more sense tbh, on xsx it was only sporadic and tbh it didnt make that much difference. Imo taking out rt was a good choice, pS5 received nice res bump it was good decision that makes much more sense, RT was overkill even for pcs without dlss. So i think Bloober spend resources good on what was needed to be done to ensure optimal experience.

 

so it wasn't intentional but still stay in statement that without rt its better with higher res

 

Maybe that's why we didn't see DF comparison video until now?

 

quite surprised that ps5 has res advantage with rt on

 

Somebody didn't get the memo: PS5 framerate advantage. Xbox resolution advantage.

Amateurs.

 

If it is not using RTAO like XSX - then that would indeed make the resolution higher.

 

Df planing to chceck medium ?

 

We were - but then Sony show and they released the patch at a pretty bad time - we are all working on other things. Maybe

 

But the game doesn't use RT in every scene? So in scenes with no RT at all XSX should have a higher res then PS5, but it doesn't.

 

RTAO wouldn't need to be constrained to the areas where RT reflections are being used. E.g. you could have a game that used RT reflections selectively, but used RTAO across all areas of the game.

 

half a year more work went into the game. Parts had to be rewritten to get compatible with the API of the PS5. This way you automatically optimize a lot. Xbox has in these cases always the "disadvantage" of being compatible with the PC version. If something works well enough, it won't get it's own more optimal code-path. When porting the PC/xbox version over to the PS5, this is absolutely necessary so the game can run.
Beeing compatible with a windows PC has always it's advantages (e.g. easy ports) and disadvantages (not so well optimized, because it is not necessary to get the game working ok).

 

I'm struggling to understand how your point is relevant? I know you can have various RT effects on while having others off.

My comment was aimed at Alex's comment as he confirmed in his PC analysis video of the Medium that RTAO isn't always turned on for XSX, which would mean in scenes with no RT at all XSX should hold a resolution over PS5.

 

Not necessarily. Without understanding how dynamic resolution is determined by the system, you have no way to know how it would behave.

 

There's a reason to have reflections on or off because not every scene will have reflections. AO will exist in every scene, what would be the reason to turn off RT AO and instead use traditional rasterization AO tricks if you already have RT AO implemented?

As well, depending on the reflection and what angles it will be viewed from, screen space reflections can look virtually identical to RT reflections in certain situations. Whereas for AO, non-RT based AO almost always looks wrong. Hence why I have posts scattered around B3D mentioning how my #1 thing I was looking forward to with RT lighting was rasterization AO tricks going away because they are so bad I always disable them on PC.

Basically, with AO, you're in a situation where you either want it to all be RT AO or you want it to all be rasterization AO tricks. Otherwise mixing the two will make it look even worse than just going with AO tricks. That's because the non RT-AO will REALLY stick out.

The loading times are not especially surprising. The Galaxy S21 has a capable CPU that is not limited to 1.x GHz. It can got much higher instead for a short time.
Resolution on the other hand is a bit more surprising. The Switch has a small GPU but it should still be much faster than the GPUs in most smartphones. It does not have much bandwidth but it should also be higher than on a "normal" smartphone.
Framerate ... I guess this is again a CPU thing. The CPU in the switch is really underpowered and could do much more if Nintendo would allow a higher thermal budget for it.
