For those frame rate issues bellow maximum usage of your hardware. HAGS + Game Mode OFF

[Czar]

Disable Hardware Accelerated Scheduling (HAGS) and Disable game mode. Both are messing with the game frame rate when in busy environments and when near a random event.

For years, I had no idea why ETS2 and ATS would have frame rate drops while GPU usage and CPU usage would also plummet.

I had a GTX 1060 6gb and assumed it was some kind of GPU component that was being over stressed outside the reading of usage %.

My settings were always under using the GPU at vsync'd 60hz at 1080p. Mirrors distance were always needed to be on MEDIUM setting.

I kept at bellow 300% scaling, always using 50 to 70% the gpu and the frames would drop.

Then, I upgraded to a RTX 3060 and to a 10th gen i5. Same thing still happened. Mirror distance to high would trigger it, regardless of any other setting. SSAO, Shadows, Light distances, AI truck cables, you name it.

Since I disabled the horrible Hardware Accelerated Scheduling AND game mode on these latest windows, both my sims (ATS & ETS 2) Have been running butter smooth since and I can put the mirror distance to ultra and still have much more hardware power left. Some hiccups are still expected for complete other reasons but those ridiculous frame drops are gone.

Its been years messing with the settings with zero resolution to what it was.

Have a try at this if you are experiencing unreasonable frame drops with much more hardware than needed to run these games.

[This does NOT improve performance if your hardware is already on the limit, but you can give it a try]

No need for questionable mods out there. Keep it as SCS baked it.

I'm going to try what you say about turning off HAGS, then I'll comment on what my experience has been.

The game mode was already disabled.

Thanks for sharing the information!

[Czar]

Hey, please do. I have found this a little more than a month ago but I wanted to have a decent mileage before sharing it.

I want to see if it resolves for others too, because just now, there are two threads just created having issues with lag and stuttering with high end PCs.

HAGS most likely the culprit. Turn the mirrors distance to ultra if previously you couldn't.

[keluvu]

Well certainly, your discovery improves performance.

I already had an Nvidia driver, monitor, in-game configurations and custom settings for the config.cfg file that had taken me hours to obtain by trying and trying. This current graphics engine is exhausting if you want the game to run as stable as possible in terms of frames, setting my goal at 60 FPS (in a 3840 x 1080 resolution).

The wait for the new graphics engine is getting really long!

Well, starting from this configuration point, which I had already managed to squeeze everything I could out of my PC and the programs, I find that with this configuration that you have shared, disconnecting Hardware Accelerated GPU Scheduling (HAGS), it has been possible for me to increase the distance of mirrors from "medium" to "high", but not only this, but also the resolution of mirrors from "medium" to "high". (Remember that Game Mode was already off since a long time ago).

I tested it for an hour through Oklahoma and Texas, the most recent and demanding DLC. I have had MSI Afterburner on the screen and the PC has been able to run the game with the new settings without dropping below 60 FPS, even crossing cities. Previously that was not possible, I tried it.

In ATS I have 1212 hours played and I immediately realized that the increase in quality to the mirrors does not affect the stability of performance, it remains at 60 FPS.

I will continue driving, observing and experimenting tomorrow. But I already affirm that your discovery, Felip Czar, is real and effective.

Thanks for sharing. As it could not be otherwise, Steam award granted.

where do i find this HAGS & Game mode Off ?

[Ryu]

Win 10:

Settings App → System → Display → scroll down to Graphics Settings → Turn "Hardware-accelerated GPU scheduling" to Off

Win 11:

Settings App → System → Display → Graphics → Change default graphics settings → Turn "Hardware-accelerated GPU scheduling" to Off

Happy that it made a difference and hear you back. Thank you.

I update what I am experiencing with this change in HAGS because I am amazed.

Another hour driven through Oklahoma and Texas, has included not only sunny days but also rainy nights and in the city. The 60 FPS remains rock solid.

And not only this, but I have increased the settings in the parameters:
Antialiasing from "disabled" to "high".
Reflection detail from "medium" to "high".

And still MSI Afterburner says that 60 FPS is constant!

The processor is an old i7 9700K (overclocked only 100 Mhz, 4.7 GHz total), 32 GB of slow DDR 4 memory (2.666 Mhz) with an RTX 2080 ti, the storage is based on two NVME mounted in RAID 0. Windows 10 installed in a separate SSD SATA. Monitor 32:9 (3840 x 1080).

And while the setup is still decent, what surprises me is that this change to HAGS has even improved performance to something I thought was already at its limit, with the current aging ATS game engine (in other games there is no problem, of course). It must be taken into account that it is a PC dedicated exclusively to gaming, it does not contain any program other than what is strictly necessary for gaming and therefore there are no extra services that are unnecessarily overloading.

The main problem (that all ETS 2 and ATS players have) is that we need to use supersampling (scaling) to be able to reduce (not eliminate, because it is currently impossible), the brutal flickering, shimmering, blinking, jagging and other defects graphics. I have it on at 300%. This scaling puts a load on the hardware that causes problems with the CPU. The current anti aliasing in the game alone (SMAA), without using scaling, does absolutely nothing against these graphical problems that I mention. New game engine, where are you, Scooby Doo?

I will continue to observe and report back. There are still a couple of graphical elements that I could level up as well, but I'll do it little by little.

Is this setting nVidia specific because I don't see anything equivalent under Settings > System > Display but I have an AMD card

[keluvu]

Hi, The Pitts
HAGS is a Windows's feature, doesn't depend on Nvidia or AMD.

Go to your Windows desktop, click start, then...
Settings > System > Display

Go bottom and there click on "Graphic Settings"
You will see then the switch to "on" or "off" HAGS

(This is for Windows 10, the one that I use, Google it for Windows 11)
Cheers!

[daniel.nole]

Also, I dont see any switch there by my Windows 10. Another way to find this switch?

[keluvu]

Daniel.nole,
the option is there, as described before in Windows 10.

May be your Windows 10 is not up to date?
I assure that on version 22H2 Home OS build 19045.3570, updated to October 14th is there.

[keluvu]

Felip Czar,
another two hours driving through Texas in all weather conditions, time and places, the HAGS "trick" really works.

Thank you again!

[daniel.nole]

No, is not there. I have read now some reports from Windows. If the parameter is not in the register you dont have this switch. Is a experimental feature and depend of the Graphic card installed. Apparently with AMD Adrenalin you dont have this switch there.
For example by my register I dont have this parameter HwSchMode.
In Spanish sorry:

Turning it off will disable certain Nvidia capabilities FYI.

I played the new 1.48.5 update released yesterday on ET2 whic and it really cleaned up this issue the 1.48.5 is said to be coming later this month for ATS
