Forza Motorsport - Performance Tips

Hi, I will try to help those who were suffering with performance as i was in the first days. Hope you all have the same luck as i did.

Tips for Performance in Current Game State

First things first

You really need a cpu with strong single thread performance to maintain 60fps at least.
If you have a cpu with more then 6 physical cores and it has Hyper Threading/ Simultaneous multi threading, disable it for the game (Over bios, proccess lasso or anything you want to use. The game really doesnt know how to use it all besides loading in the current state.
Enable resizable-bar on nvidia profile inspector if you have nvidia or SMA in AMD GPU (I just tested Nividia because i dont have access to a AMD powered GPU capable of the same performance or even to run the game at low). It will not increase performance, but will improve a little VRAM usage and stability.
Update the driver, i dont know if amd already uploaded one. But the nvidia game ready driver improved a bit.

Now to the game settings

First of all, if you are switching between configs and nothing changes, i recommend deleting the configuration file and start the game to generate it again, located at:

Steam:

%LOCALAPPDATA%\Microsoft.ForzaMotorsport\User_SteamLocalStorageDirectory\ConnectedStorage\ForzaUserConfigSelections\UserConfigSelections

MS Store:

%LOCALAPPDATA%\Packages\Microsoft.ForzaMotorsport_8wekyb3d8bbwe\LocalCache\Local\User_GamingLocalStorageDirectory\ConnectedStorage\ForzaUserConfigSelections\UserConfigSelections

It solved a problem for me with the intro, the first audio was always crackling.

PS: There you can find some configs that suggest support for nvidia frame generation, absent from the game currently.

Now for the real part, the main settings from my testings.

Track texture quality: Thats the BIGGEST impact on the game, its mislabeled as textures only, but it is related to LOD too, this seriously impact gpu and cpu performance, the most stressing test isnt even the benchmark for this, is the complete Suzuka Circuit, i was getting like 37 fps even on test drive. The difference from medium to high for me is almost 50% or more.

Shadow: Second on the list of impact besides obvious ray tracing. medium to high is a big impact in performance, but not nearly as track textures.

RTAO: If you have RT enabled, its a big impact too, but i could not notice any big difference between low to high, but i may be blind.

The rest of the settings is normal, just see if you want or not. I ‘ve setted most at medium just because i dont want to keep changing setting by setting anymore and for VRAM limitations.

Notes

Dynamic render quality works as DF stated. low = 720p, medium = 1080p, High = 2k, and ultra = 4k.
Every setting you change, make sure to restart the game, sometimes it can apply just by reloading the track, most times dont. So, make sure to restart it.
To DLSS/FSR work, you need to set resolution scale to auto.

And that’s it from what i remember from my investigations yesterday. Hope it Helps at least somebody.

Here is the settings that i used to get 60fps on BM as an example:

I still prefer to use DLAA instead of DLSS Quality, because ingame i have not experienced any framedrops from 60 except for cutscenes that the bottleneck is the bad use of CPU.
