Why Is ATS Stuttering? In Other Words, What Is Scaling?

Here we cover information about Scaling on a basic level. This is an important feature of the SCS games that allows it to be played on less than desirable PCs.

Note these tests were completed on an AMD 5600X processor, an EVGA nvidia RTX 3070, with 32GB of RAM and an M.2 solid state drive.

100% scaling was 246fps in the latest vanilla truck the #InternationalLT, and at 400% scaling was 109fps. This is with very few mods, and none in traffic or used in the video. Add some mods in there with traffic trailers and upgraded textures and you are well on your way to stuttering video.

This game even Stutters with a 3090. Come on SCS, get your shit together

Is it just me or does this dude look like he is going to steal the chipmunks.

My scaling was already at 125%, but I had to change the resolution from 1690, to 1440 and my game is running smoothly and doesn’t stutter then crash after 15 minutes into the game like it use to! Thank you for the info!

brilliantly said bro.... i always tell my followers to never exceed 200 scailing because 200 is a sweetspot between quality and performance

Tried everything about graphic 3d settings, hardware accelerated gpu scheduling off, disabling full screen optimization, then steam notification off, disabling animated avatars on steam... but in the end playing "steam-offline" actually helps in my ets2 and ats!

Scaling does some of it but there are other things you can do to help.
Launch settings can be added by going to steam, right-clicking on American Truck Simulator, you will see properties. Then you should see a blank text input box,
this is where the launch settings go. There is different variations of launch settings so let's go with these.
(PLEASE SELECT THE ONE FOR YOUR RAM AND COPY AND PASTE INTO THE EMPTY TEXT BOX, SEE PHOTO FOR EXAMPLE)

Step 1
8GB RAM:
-mm_pool_size 4096 -mm_max_resource_size 100 -mm_max_tmp_buffers_size 1000 -nointro -unlimitedlog
16GB RAM:
-mm_pool_size 8192 -mm_max_resource_size 100 -mm_max_tmp_buffers_size 1000 -nointro -unlimitedlog
32GB RAM:
-mm_pool_size 16384 -mm_max_resource_size 100 -mm_max_tmp_buffers_size 1000 -nointro -unlimitedlog
64GB RAM:
-mm_pool_size 32768 -mm_max_resource_size 100 -mm_max_tmp_buffers_size 1000 -nointro -unlimitedlog

Depending on your PC specs copy and paste the line that matches your memory specs on the left.

Since 1.50 my game started to lag and stutter. I use both vanilla truck and trailer and paid mods. When I use vanilla truck by using minimal and no mods I get the same experience. I turned the scaling down and still no improvements.

[estebanr]

Finally someone explain this setting properly. Thanks!

[TheGreatSimulator]

This actually helps quite a bit. This may explain my stuttering. I have a billboard replacement mod in and I am constantly scaling to 400. I'm going to apply this method and see if it helps.

[DNASocial]

Wow this was super helpful! I genuinely didn't understand that this was how scaling worked and now feel like i understand it fully! I also like your suggestions on what to set our scaling at depending on the number of mods we have. Thanks for another super informative and helpful video!

[RizkyAshary]

actually there is another way that I have used to boost fps significantly, reduce the visibility or draw distance map, while in the cabin truck, it worked 💯

[lifeisagift.cherisheverymoment]

Thank you for explaining Scaling in a way a non-dedicated gamer can understand.

[realbento]

3080 12g here. I'm with a fresh install. No mods, just stock game with 200% scaling (2560x1440 Monitor).. still getting A LOT of stuttering through urban areas. Really, really annoying and thinking about stop playing bcause of this.. this is sad

[jasonPeterman-yxqe]

Hi with this knew update with the 1, 51 out. I have a 3080 graphics card and when I go in game when driving down the free way or a road the un coming traffic trucks flicker what would that be causing ?

[roger]

My game also seems gray ish idk what's up with the vivid colors I've seen in the trailers and screenshots

[GianfrancoBelloliW]

Great explanation. Everytime they release a new version I feel I have to scale down, so instead I have reduced the mirror distance in the config file, and toggled off the mirror in the normal view. I will probably need to upgrade my laptop eventually....

[lachancla]

The stuttering only occurs on certain parts of the map mainly in the cities. I get smooth frames while driving on rural roads/between cities but when I drive through the newer cities (Like Montana, Wyoming, reworked California cities) the game will stutter/freeze for 2-3 seconds before returning to normal. I’ve already tried disabling in-game v sync, adjusted the scaling from ranges of 100-200%, lowering the other graphic settings medium to low, and enabling the control panel v sync. I’ve also tried updating my drivers, but it didn’t really make that much of a difference. I only run C2C, Midwest expansion and a couple of sound mods.

[KristianWontroba]

Best explanation of this. Subscribed!

[iiltaylorlii]

Yeah, this helped my issue a bit more. First Person would look slowmo issue and it seemed to be slower than in a 3rd person camera angle.

[joemac]

That would explain why some content creators games would crash when they would enter a large city when they were streaming. Their videos looked great but they crashed in big cities! Couldn't handle the rendering.
