Forza Horizon 3 [XO, XPA]

Actually, now that I think of it, it gets tricky if they went with 60fps just because of online racing. Do you split up the userbase into 30fps and 60fps players? Probably easiest just to keep them equal, or the scorpio players would have an unfair advantage. That's regardless of whether they could hit 4k native, dynamic or checkeboard.

The "unfair" advantage this will become the norm if consoles move to faster upgrade cycles. It's unavoidable. No different than PC with multiple configurations ranging form graphics settings and refresh rates. Play with what you got....
 
Yes, racing games that are already doing physics simulations 60 times per second (or higher) won't be limited by the CPU WRT to graphics rendering time.

So, in this case, the relatively small increase in CPU speed for Project Scorpio won't be much of a factor in whether FH3 at 4k will run at 30 or 60 FPS. Especially if a FH3 patched for 4k is also able to take advantage of the GPU offloading of draw calls from the CPU. I'm not sure if FH3 was already doing that on XBO or not, and to what extent if it was.

Thanks for the explanation regarding cpu.
But what about gpu, going from 1080p30 -> 4k60 is a big jump in rendering requirements.
Is it a matter of doing it, but not ramping up quality to ultra etc
 
Partly, we don't know what framerate a game can actually push without the 30 fps cap.

For forza horizon in particular, I'd wonder how much GPU time is spent on the 4xMSAA and whether opting for just a post-process solution would free up enough resources.

What's interesting is that they were already experimenting with 4K res (Advancements in Tiled Rendering, GDC15) and cutting down render time.

That said, it is a tall ordered true. o_O

Even if it runs at average 45, highest 70, it's the minimum that matters and their stringent on not dropping frames.
So at 60 would need just as much headroom to maintain the min 60.
 
Obviously.

Edit: With the 30fps cap in place, we don't know what the minimum (or anything else) is. IIRC, there were some frame drops in DF testing, but I don't recall the context.

The point of my post was looking at what changes can be made - removal of MSAA & tweaks to the clustered renderer (tile size adjustments, for example).

But again, 8x throughput is again... a tall order.

again.

Replied prior to your edit.
My point was that the actual unlocked frame rate may not give a good or any indication of what it can do at 4k.
Any other game that has the odd dip, it may give a better indication.

Edit:
I thought it was locked, if there are the odd frame dips, then they must be pretty close to 30min.

Think it's harder to double framerate on gpu than going up resolution, so doing both will be interesting to see them do if they can.

At any rate, a more solid source than some translation would be appreciated. This just seems highly unlikely.

It wasn't easy to find that news. Actually, investigating further, the original source was a magazine called Hobby Consolas. Their headline is that FH3 is going to run like in Windows 10.

that shouldn't be much of an issue if you adapt the multiplayer mode to the lowest common denominator or you can apply filters.. Hopefully future games will be based on Scorpio and ported to Xbox One without framerate loss even if that means running the game at 720p.
 
Been playing the game at 4k on my new PC and I've got some good news for those looking forward to playing the Scorpio version. It looks like 4k at maxed out settings might be easily doable at 30 fps. The game, when locked at 30 fps, is using about 40-45% of my GPU, and up to 6 gigs of vram (with 8x MSAA!). With some simple math:

3584 cuda cores x 2 x 2000 core clock = 14.33 tflops
14.33 tflops x 0.40 = 5.73 tflops
14.33 tflops x 0.45 = 6.45 tflops

Now, this is not the most scientific method of looking at this but I'm sure if they drop the MSAA to 4 or even 2 times they can get it at a perfectly stable 30 fps with all settings maxed on the Scorpio (minus MSAA).

(first % on the gpu is usage and second one power limit)

I'm not sure if they have headroom for something extra (maybe engine optimizations) but the game looks gorgeous as is already.

I don't have the game yet, but this looks like it would be a blast.

An idea stolen at GAF would be to make the track lit up neon for nighttime racing.

PC Update Improvements

Alongside the release of the Forza Horizon 3 Hot Wheels expansion we are pleased to announce numerous critical improvements included in the Windows 10 PC version of the game. These improvements are included in today’s automatic update, and do not require the Hot Wheels expansion to take advantage of.

Expanded Driving Wheel Support

With the most recent update of Windows 10, Windows Creators Edition, we have expanded our list of officially supported steering wheels for PC. The full list of newly supported wheels:

· Logitech Driving Force GT
· Logitech MOMO Force Feedback Racing Wheel
· Logitech G920
· Logitech G29
· Logitech G25
· Logitech G27
· Fanatec ClubSport Wheel Base V1
· Fanatec CSV2
· Fanatec CSR
· Thrustmaster TS-PC
· Thrustmaster T150
· Thrustmaster T500 RS
· Thrustmaster TMX V1
· Thrustmaster TMX V2
· Thrustmaster T300RS
· Thrustmaster TX 458 Edition
· Thrustmaster TX 599 Edition
· Thrustmaster TX Leather Edition
· Thrustmaster TX F1 Edition
· Thrustmaster TX GTE Edition
· Thrustmaster RGT

Improved CPU Performance

We have observed that a large portion of players are CPU limited when trying to run Forza Horizon 3 at high frame rates, including locked 60 FPS and unlocked. By analyzing telemetry, we have developed targeted optimizations for this group of affected players by increasing the number of concurrent threads used by the render architecture. We have taken further advantage of DX12 capabilities to allow the visuals to be processed out of order during the frame, in order to reduce synchronization stalls and decrease CPU execution duration. These changes result in a significant CPU performance gain on High or Ultra settings when running on PCs of Recommended spec or better.

Updated Thread Model

We have updated our threading affinity model to make better use of all available cores. Along with this change, we have added a new graphics option to disable the new model, should you prefer. This option can be found in the Video Settings menu under “Threaded Optimization”.

More Graphical Options

We have also added some additional graphical options to improve framerate for those playing on lower specification PCs. These include:

· Dynamic Geometry Quality now has a Very Low option
· World Car Level of Detail now has a Very Low option

These are combined with some existing options to create a new “Very Low” preset that can be used with dynamic optimization.

Additionally, all options have had their descriptions updated to include information on how each setting affects the CPU performance, GPU performance, and available VRAM, so that players can better understand the performance impact that tweaking each setting will have.

Updated Minimum Specification

Along with the performance improvements coming with this release, we are lowering the minimum specification to reduce the CPU requirement and the NVIDIA GPU requirement.

Minimum Specification

i3-4170 @ 3.7Ghz

GPU
NVIDIA GT 740 | AMD R7 250x
