Stutter Fix?

[NHSynthonic Orchestra]

So for years i've had problems with ETS2 with stutter, the game will slow down to around 25-30FPS for a few seconds then jump to 60 making it speed forward as if it was catching up with itself, i've had this problem for years on many different machines, I did have a mod that stopped this and made it run smoothly, but i've not played in a while and the new updates have broke the mod, removing it has put the game back to its lagged state.
Any possible mods or easy fix? (I dont believe it's my graphics since I used to play it on Ultra)

Is it happening all the time or just in cities and busy areas? Do you have map mods installed?

Don't know if this may help you, but I had the same issue just recently when I tried, out of curiosity, to run it on OpenGL rather than DirectX. After one delivery I went back to DirectX.

You can quickly check in your game.log.txt file which one of the two you used last time you played, just open the file, search for "Euro Truck Simulator 2 init ver.1.33.2.19s" and read what follows shortly below there.

It does happen in busy areas, I dont have any map mods installed but I used to have some texture mods installed.

I have tried both OpenGL and DirectX, OpenGL run fine, however half the textures are missing (could be due to the texture mods) and DirectX is just stutters.
However this has been a problem I remember having without mods.

Texture mods MAY have caused this issue. I'm convinced that mods I used in the past have still left something in the system, because I began to run into performance issues in my original profile, even after disabling all mods. I haven't had those issues since starting a second profile. Coincidence? Who knows. But it worked.

I'm assuming you've tried various graphics settings? Including things like refresh rate? I found out a while back that the default refresh rate doesn't always work best. I seem to remember having to change it to 59 or 60. Stuttering disappeared after that.

Only other thing I could think of might be a GPU driver update.

I have tried with the graphics settings, what I might do is save my profiles folder and delete ETS2 and reinstall in clean and put my profiles back on, it could be old Mod files messing with the game, I'll report back in a few hours to update how it's going

Anything is worth a shot. Fingers crossed.

this also happens to me, BUT 20-25 to 60

Open GL 64 bit, Reduce mirrors detail and resolution (low or Medium) -leave draw distance at Ultra. Smooooth as silk (rock steady 60fps) but you must use Vsync as well, if not it will go from -for me; 90 - 45fps, Regardless. Everything on Ultra x 400% scaling using a EVGA SC GeForce GTX1060 6GB and a very,very good and fast single core I5-3570k. Drop Texture mods as has been said.

So, I deleted all my mods, uninstalled ETS2 and then deleted the files it left over.
after reinstalling I played on my main save without any mods, the game works better, I have ran into this stutter around 11 times in the past hour but nothing as bad and constant as last time,around 45-60FPS, main places i've notices it appears at are: busy areas, intersections, motorway gas stations (and the lit up strips before and after)
It seems its a bug in the main game itself that the old mods fixed. i'm going to try Open GL now to see how that fairs with this stutter.

Sounds like it's less irritating now. Improvements are always good!

If you find a Fix, I would be curious, as I am getting the same problem too

Sounds like an issue running in the back ground, in the last couple of years ive had i5 2500,4790k, 6700k and my current 7700k, also gone from an Evga gtx970 - Evga gtx 980ti ftw- Evga 1070ftw to my current Evga gtx 1080ftw and ive never had lags/spikes/stutters other than when i had alt/tabbed from another game and forgot to close it before running ets2, also the game runs flawlessly from my Samsung 970 pro 1Tb.

Well i did just post a 'fix'. Even if the 'fix' works for him/her that i put up, doesn't mean to say it's going to work for you. Your hardware isn't the same as mine or anyone elses. Vsync, mirrors and OpenGL nailed it for me after YEARS of trying everything and going through several OS,hardware upgrades. The most stable platform? Win 7 64bit -says it all since it's an open OS still and not riddled with bloat and DRM oppresive features. Says me with 28 years of building my own PCs. But your mileage may vary if you have no comparisson with Win10 and Win7 (i do)

"Win 7 64bit -says it all since it's an open OS still and not riddled with bloat and DRM oppresive features."

Windows 7 is not open software. I think you meant still supported by MS.

As for the hitches in frame rate in ETS2. It's the engine. I just wasn't meant to do what we are asking it to do. The density and features added to the game are a huge load for it. It stutters under high detail and busy places because it is trying to feed new data. With stock settings it survives pretty well, but with extra mods can bog down. Even with super modern hardware. You have to think this engine has been having new game functions being heaped on it since 2012!

The best thing you can do lower detail or number of views (mirrors and extra displays) and get a SSD. This lowers the amount and size of items that must be updated. The SSD lowers the amount of time it takes to stream those items to the game. This info can generally be applied to anygame with performance issues.

For instance, I don't run texture mods or anything but am running a 3 x 1 monitor setup. So I don't run at maxed out detail because it slows down in cities. I just lowered some detail until I am getting 60fps in almost all situations. I have a 1080 GTX and 4770k, running fastsync with 60fps cap.

Also remember that every extra mirror or display is another view for the game to render. Some trucks can have 2 side mirrors, plus a front mirror and a seperate view for each monitor. So if you drop mirror distance or detail it can impact fps quite a bit.

SCS has had a project for engine upgrade for at least a few years. We'll see what they can come up with.

'Open', meaning supports SecuROM and safedisc games, I'm sure i didn't need to say that..it was self explanatory.

open OS still and not riddled with bloat and DRM oppresive features."

..That alone would be the biggest clue.. I have a wealth of old games that i can happily install on 7 but not on 10 -and don't work none the less, regardless.
Also, i have a helluva lot of GoG games that still don't function properly on Win10 yet flawlessly on 7. You have to trawl the net for 'possible' third party fixes if they indeed work! It's like the worst DOS system. Regardless, we never got 'Free' Win 7 but forcebly 'enrolled' in Win10 -no such thing as free. Soon features will be subscription based for Win 10.

That's the reason ETS2 runs better on Win7 as do a lot of pre-Win 10 games.
