Well folks, here it is: The PS5 Pro Update. You guys know what to do and for the love of all that is holy, please remember to post findings pertaining to these threads in these same threads in the OP (or else I'm sending Mariah Carey your coordinates):

Now post away.

 

[Eggstor]

(or else I'm sending Mariah Carey your coordinates):

That is approaching a Geneva Convention violation.

Still, I'd allow it if I had a say in the matter.

 

[Nakano219]

The race lineups for the pre-update Jimny Cup races have been updated to have some of the AI in the new Sierra.

I don't know if that's just standard for all events nowadays, but the Jimny Cup is an easy one to check.

 

[Islaygaz]

Any new manufacturer paints added?

That's been pretty much the standard, at least since the Spec II update.

 

[snowgt]

The Porsche Mission X's weight in game is 1600kg, if anyone is interested. (Weight doesn't show anywhere)

 

[omegasc]

There is no longer a 30fps limit anywhere that I could check (e.g. prize roulette, café presentations), in Prioritize Graphics mode (tested on 120hz VRR PS5 Pro)

 

[wheelhp]

More wheels were added than just the rotiforms.

Brick Volvo has a 1khp swap now.

Both these things were in the patch notes

If the forthcoming real car is that heavy then Porsche has lost the plot.

 

[NJ72]

Someone hasn't seen the weight of the new M5 and it shows 😂

 

[Chevy Heavy]

It appears the Legendary Car Dealership has been expanded. There are currently 19 cars in there. Perhaps someone stumbled across an old barn full of classic cars and this is a one-month thing. I guess it remains to be seen, but a welcome addition regardless.

 

[Aloha62_2]

Welcome to electric cars.

Get ready for a lot of road damage.

 

[Eunos_Cosmo]

Other Improvements and Adjustments​

1. Cars
　- We have added the cockpit view to the following car:
　　・Mercedes-Benz AMG Vision Gran Turismo

​

Ok this is actually cool. Has anyone checked this out yet? It's one of the more interesting Vision cars but I was disappointed it didn't have an interior.

The Ferrari Ingrid is a duplication weirdly

PS5 fat owner here (perf mode, no 120Hz), I drove at Mount Panorama and felt there was something different, same thing after at Laguna Seca. I was pretty sure of me after a lap around Le Mans, draw distance has improved.

I've got far less popping trees, they looks different too like the platanus range at the entry of Mulsanne straight. I wouldn't be surprised that they lowered their quality, which would also explain why the game takes less disk space than prior to the update. I should have taken some screenshots before the update...

That's because there're plenty amount of Special Picks cars now.
The number will be 10 if you exclude the Hot Cars and Special Picks.

 

[Meythia]

I wouldn't be surprised that they lowered their quality, which would also explain why the game takes less disk space than prior to the update.

Ha, I thought the same after looking at my screenshots.
Has it always been this way, is my memory of the "prior PSSR" resolution that muddled?

 

[P-Courty]

It seems the physics have changed, I have been practicing for the AMG VC and on Tuesday the car felt understeery going into corners, but last night it felt like it did after the major physics update either 1.49 or 1.50 (whichever one it was).

Now trail braking is back to smooth suspension movement and no more understeer, the car feels great again.

Not sure if they have adjusted all suspension geometry again or whether a few cars have been adjusted

 

[snowgt]

If the forthcoming real car is that heavy then Porsche has lost the plot.

It's an EV. 1600kg is very light for current battery technology with decent capacity.

 

[Majorlazer]

If the forthcoming real car is that heavy then Porsche has lost the plot.

That's not too bad given it's all-electric and the Ferrari F80 is 1679KG curb weight. The W1 is only lighter due to being RWD and hybrid, rather than full-electric. Honestly, Porsche getting the X to be so light is once again a testamant to their engineering. No-one can match them when decide to really go for it.

Are from previous updates, but otherwise spot on!

 

[IngWeltschmer]

Don't want to get it wrong, but weren't they updated only when that race was included in weeklies? i.e., its inclusion in weeklies led to the field being updated?

Honestly, Porsche getting the X to be so light is once again a testamant to their engineering. No-one can match them when decide to really go for it.

But why would they spend that much time engineering a car that nobody wants? I don't really care how well they can engineer some stupid thing.

It's a Porsche, people will be begging them to buy one. We are not their customer base or target audience.

I literally have one in my driveway (an affordable one) and the entire reason I got it is because the next version is going to be electric. At that point, the used prices of these things will go through the roof.

Porsche is going to lose their ass on the electric Boxster, guaranteed.

Impeccable logic. Long live the 987 S!

 

[Obelisk]

Bumper cam HUD has been reorganized to place all of the assists along the bottom of the dials, allowing for a larger MFD (I think - the assist icons definitely got moved).
