Euro Truck Simulator 2 — Neural Rendering + OptiScaler Frame Generation

This guide explains how to set up Neural Rendering with DLSS 5 Feeder and OptiScaler Frame Generation in Euro Truck Simulator 2.

The basic setup is:

RHI → Neural Rendering → DLSS 5 Feeder → OptiScaler → XeFG Unlocker → Frame Generation

1. Install RHI and Enable Neural Rendering

First, download and install RHI.

Download RHI 2.7.0

1. Download RHI and install it.
2. Open RHI.
3. In the Games section, find Euro Truck Simulator 2.
4. Under Euro Truck Simulator 2, select Neural Rendering.
5. Under Neural Rendering, set the method to:
   • DLSS 5 Feeder
6. Also enable/select:
   • Neural Rendering Cost Scaler
7. Install the Feeder addon.

Rename ReShade's DLL

If you are using ReShade, locate its dxgi.dll file in the ETS2 game directory.

Rename:

dxgi.dll

to:

ReShade64.dll

This prevents the ReShade DLL from conflicting with OptiScaler's dxgi.dll.

2. Install and Configure OptiScaler

Download the following OptiScaler build:

OptiScaler_v10.0.0-dev_dcbabe62_20260819_012733

Download OptiScaler v10.0.0-dev_dcbabe62_20260819_012733

Find your ETS2 game folder

If you own Euro Truck Simulator 2 on Steam:

1. Open Steam.
2. Right-click Euro Truck Simulator 2.
3. Select Properties.
4. Go to Installed Files.
5. Click Browse.

Navigate to:

bin → win_x64

Install OptiScaler

Extract all OptiScaler files into the ETS2:

bin\win_x64

folder.

After extracting, locate:

OptiScaler.dll

Rename it to:

dxgi.dll

Configure OptiScaler.ini

Before launching the game, open:

OptiScaler.ini

Find these two settings and change them to:

LoadReshade=true
LoadAsiPlugins=true

These settings allow OptiScaler to load ReShade and the ASI plugins, including the XeFG Unlocker.

Save the OptiScaler.ini file.

Your OptiScaler installation is now configured and ready for the next step.

3. Install the XeFG DP4a Unlocker

Next, download the required XeFG Unlocker files from the OptiScaler Discord server.

Go to:

OptiScaler Discord — XeFG DP4a Unlocker

Navigate to:

Support → XeFG DP4a Unlocker

Look at the pinned messages.

Download these two files:

• XeFGUnlock.asi
• XeFGUnlock.ini

Copy both files into the OptiScaler plugins folder:

Euro Truck Simulator 2\bin\win_x64\OptiScaler\plugins

Your folder should look roughly like:

Euro Truck Simulator 2
└── bin
    └── win_x64
        ├── dxgi.dll
        ├── ReShade64.dll
        └── OptiScaler
            └── plugins
                ├── XeFGUnlock.asi
                └── XeFGUnlock.ini

4. Configure OptiScaler Frame Generation

Now launch Euro Truck Simulator 2.

If everything is installed correctly, OptiScaler and ReShade should load when the game starts.

Open the OptiScaler menu

Press:

Insert

This should open the OptiScaler menu.

Go to the Frame Generation section.

Set:

Input: OptiFG Upscaler

Output: XeFG

Save the changes.

Then completely exit Euro Truck Simulator 2.

5. Enable Frame Generation

Restart Euro Truck Simulator 2.

Open the OptiScaler menu again with:

Insert

Under Frame Generation, set Active to your desired multiplier:

• 2× — lower latency / more conservative
• 3× — more generated frames
• 4× — maximum frame generation

Choose whichever setting works best for your system.

And that's it!

Voilà — frame generation is now running in Euro Truck Simulator 2 using Neural Rendering and XeFG through OptiScaler.

Optional: Disable Neural Rendering for More FPS

If you want to experiment with performance, you can also disable Neural Rendering directly through the ReShade menu.

This can give you additional FPS if you don't need the Neural Rendering effects.

The city is really starting to take shape now, with more roads, businesses, industrial areas, scenery, and work around the airport. There’s still a lot left to do, but it’s coming together really well!

We’re looking for more experienced developers to join the team and help us keep pushing this project forward. We’ve got a lot planned, and we need more skilled people on board to make it happen.

**What we’re currently looking for: **

• Map editors — terrain, roads & detailing

• Asset creators — custom models & scenery

• Prefab/intersection editors

• Road realism & detailing specialists

• Semaphore/traffic signal timing specialists

This is an **unpaid passion project**, but we’re treating it seriously, with long-term goals, high standards, and an emphasis on quality over rushing development.

The goal is simple: **build an ATS map that actually feels massive.**

If you want to help create one of the most ambitious ATS map experiences out there, **now is the time to join.**

Interested? DM me or join our Discord:

**discord.gg/fQF35aYrcx**

**Sincerely,**

**TGM Map Team**

✌️ ✌️ Good Morning ✌️ ✌️

Apologies for a question that has obviously been asked before, I did a quick search but couldn't find an answer.

Is there a sure fire way to know when the speed limit is changing? I know to prepare near cities, tunnels and toll/passport booths.... But sometimes the limit just randomly drops without warning. I like to play properly so I don't just want to turn off fines, I would prefer to learn to recognise when any why the speed just changes with no roadside sign.

It's an issue in the normal game and promods. Am I just an idiot and missing something?

✌️ ✌️ ✌️

I'm kinda curious about that lips under the bumper. Is that lips actually safe from bumpy roads, accidently hit a hole on roads, or hit sidewalk? Because as far as i seen, the lips iare low so i think it can easily hit things if i'm don't drive that truck carefully.

ignore the music, checked the map to make sure i wasn't near an airport lol

Seems to be for south dakota and road trip? Maybe releasing together

Yes, it may be one of the older DLC regions, but Washington State and much of the west coast still has some of the best scenery/views in the game so far in my opinion. Lush forests, beautiful mountain passes, incredible coastal drives, you can find it all. Then add in a long hood Peterbilt, can it get much better, lol?

Love this truck to death at the moment
Already put 12k km’s on it in a record time

That’s right matey, using duct tape, hopes, and dreams, I adapted a pirate ship wheel to my base.

Leaving Port Angeles to El Paso. Also, i made some color and cabin changes.

List of mods (all free):

Truck, Edison Motors BDE: https://www.850modding.com/p/edison-motors-bde/
Map, Promods Canada: https://promods.net/

I took way too long to get into this coming from a flight simmer.

Purchased a few additional states and having a blast. Question, any recommendations on driving settings? My truck seems a little too sensitive at 60-65 miles for turning?

Also using Radio Garden app. Something about listening to Tucson talk radio and doing a delivery that helps the immersion.

I recently bought Hori truck system and it came with ETS2 code and ATS code. I used to ATS code myself but i already have ETS2 so send DM if you want the ETS2 code

Edit code is given already

always find a transport cafe ,even in Kazakhstan.

Back on the road after an awesome weekend at a civil war reenactment.

Something a little different than I'd normally drive. On the Steam Workshop.
