Performance issues on a decent PC

[Sevenfold]

Hi, just wanted to see if anyone running a decent specs PCs is having performance issues? I've noticed lower performance after the UI update, all of the sudden I'm getting drops to 30-45 FPS, sometimes even lower and not sure what is causing it. I'm running

GeForce RTX 3070 Ti
i7-11700K 3.60GHz
32GB RAM

I'd imagine 60 FPS should stay consistent - I have just "default" Ultra settings in game. Game is on HDD but always has been and it's never been an issue prior to the UI update. Any ideas what can be causing it and what setting should resolve the issue without having to drop down setting too much or at all?

Reduce your graphic settings and have the game on a SSD.

Your FPS will drop when you use Mods or mine does, i still get over 60 but before Mods it was 110+. As already said just adjust your Graphic Settings, some switch AA off which can give you a few more Frames, just play around till your happy.

It is the update - game is on spots not optimised. Patch to fix this will come late summer. Until then lower certain graphical settings.

I lowered scaling 125, IIRC, and got the FPS up to 90. (Using a 3060 card and a ultra wide screen)

This is how I have my game set up. Using an EVGA RTX 3080 FTW3 12GB.

What I find that works best is renaming the config.cfg file to like config_backup. Game will create a new one when launching. This will reset your graphic options. Close out of the game.

Now open config.cfg file in Documents/American Truck Simulator folder with notepad and make the following changes:
uset r_buffer_page_size "30"
uset t_averaging_window_duration "240" <-- set to you monitor default refresh rate
uset t_averaging_window_length "120" <-- set to double the fps that I locked the game to which is 60.

My in game graphics settings are at Ultra(Mirror distance is high). Individual settings are:
Refresh rate: Default Refresh
V-Sync - Disabled
FPS Limit: 60

Scaling: 400% <-- personal preference
AA: TAA
TAA Tuning: Adaptive Clarity
TAA luma sharpening: 1.50
SSAO: Disabled

Individual graphics below this is personal preference along with having SSAO on. I hate the screen door look it shows on trucks like the W900 where you can see the hood so I disable it. SSAO is also known to eat up frame rates.

Traffic mods(Municipal Police, Jazzycat, and others) are causing frame stutters based on recent comments that I've read, even if they are updated for 1.50.

I would suggest moving the game to an SSD if you have the option. Mechanical hard drives are just too slow to access information in my opinion.

ETA:
CPU: Intel Core i5 13600k
RAM: 32GB Corsair Vengeance 3200Mhz(kept from my previous system)
GPU: EVGA RTX 3080 FTW3 12GB
I specifically went with DDR4 when I built this system last year because DDR5 was still out in left field with extremely high prices.

Keep in mind that upscaling means everything will be upscaled.
Which means these totally nonsense 4k to 8k mods and their textures will also be upscaled 4 times.
4k -> 16k
8k -> 32k

Which is way too much for most systems here...

[Sevenfold]

Thanks all, I'll play with the config as suggested while we wait for a patch to bring back the previous optimisation, if that will bring it back, that is. Cheers!

aymazingats settings are working for me. I use ssao at medium cause i like the film grain effect on the foliage. I will be setting this up for ets2 also.

Sevenfold,
You don't say what resolution the monitor has nor the Hz. This is critical.
But you say you use a mechanical disk. This is also critical.

My recommendation, install at least one SSD (better if it is NVME) and limit the monitor frequency to 60 Hz.

To configure everything else, here are all the parameters I use. They might work for you, you have an Intel and an Nvidia. It works great for me with everything maxed out (except SSAO) at a rock-solid 60 FPS.

Monitor resolution: 3840 x 1080
Monitor Hz: 60
Power Energy mode in Windows: Best Performance (Win 11)
Hardware Accelerated GPU Scheduling - Off
Game Mode - Off

Nvidia drivers: 555.85

Program Settings for ATS / ETS 2 in Nvidia Control Panel:
Image Scaling - off
Anisotropic filtering - App controlled
Antialiasing FXAA - off
Antialiasing Gamma - off
Antialiasing mode - off
Antialiasing setting - none
Antialiasing transparency - off
Background App Max Frame rate - 20
Cuda Gpus - All
Cuda Sysmem Fallback - Driver default
Low latency - off
Max frame rate - 60
Multi frame Sampled AA (MFAA) - off
OpenGL GDI - Auto
OpenGL rendering GPU - (select your Nvidia Card)
Power management - normal
Texture filtering Anisotripic - off
Texture filtering Negative lod - allow
Texture filtering quality - quality
Texture filtering Trilinear - on
Threaded optimization - on
Triple buffering - on
Vertical sync - Use the 3D app setting
Virtual reality pre rendered - Use the 3d app setting
Vulkan/OpenGl - auto

Nvidia Control Panel:
1) Display / Change resolution / Use Nvidia color settings
desktop color - Highest
output color - 8 bpc
color format - RGB
output dynamic: Full

Display / Adjust desktop size and position
Select "No scaling" IMPORTANT!!!
Set "Perform scaling on" to Display

2) Video
Adjust video color & video image - set both to Nvidia settings

Pc Specs:
i7 13700K (Not overclocked)
RTX 4070ti
32 GB DDR5 RAM (5,200 Mhz)
Storage: NVME Pci 4
Win 11 (Home, up to date) dedicated to gaming, not any programs installed except MSI Afterburner and Omen Gaming Hub.

Inside game AA:
TAA (only)
Adaptive Clarity
Luma: 1.50

Inside game graphics:
Refresh rate - Default refresh
Vertical sync - Enabled
FPS limit - 60
FPS limit backg - 20
SSAO - disabled
Depth of field - disabled
Reflection scaling - 100%
The other parameters: MAXED

The config.cfg file was created by the game from scratch. I have not modified any parameters
No boot parameters in the steam client, just "-nointro"
(I had both modified in the past, in version 1.49 and earlier, but as I say, I see that it is not necessary)

Always drive from cockpit view (even when parking, without tricks of switching to third-person view). I say this because it was always said that from the cockpit view there were more problems with FPS drops

Linking to a known channel that does nothing but do extreme speculation is quite sus. They take snippets of video and make it appear that is what SCS meant by what the channel states.

SCS had to release a blog post specifically about this particular channel because of what they were doing with the wild and unfounded crap they were posting.

That is not an official SCS video, it is a well-known source of false information and has been disclaimed by SCS as unreliable and untruthful. In other words, lies for clicks.
