First of all thank you so much for this, I was so sick of all that flickering and this removed almost all of the aliasing.

Any good options to help with the framerate during night time? Right now I have a constant 50-70fps during daytime, unless it's a heavily wooded area, where it drops to 45, not ideal but still okay for me, however as soon as night time falls and you see the yellow/orange lights around cities and highways, the game drops down to 35, all the way down to 20 if there's a lot of cars around you. Funnily enough, changing the camera to anything other than the 'inside camera' jumps up to 50-60 again. (In fact the roof camera gives me 110fps! lmao) I tried various in-game settings but nothing seems to help.

@Pit-O-Matic - You can try the TAA method, lots of people raving about that on the SCS forum, until it got kicked off for turning into a paid mod.

With every game update the game becomes more demanding to run, SCS increase the games requirement statement, but never bother to make the game actually use all of your available hardware, new high end pc or old pc like mine, it doesn't matter, we all have multicore cpu's but the game continues to use, primarily, just 1 of them.

The interior cam is the must demanding due to it's changing lighting levels, animated dash, hanging objects and multiple mirrors, each mirror is a simpler rendered view that's added to the rendered driving view, lots of visible mirrors, lower fps. Mirror distance set to low should help.
The roof cam suffers from none of the above and also has a much lower draw distance, therefore higher fps.

If you previously ran the game on ultra with 400% scaling with acceptable fps then you should be able to use 100% 4xMSAA 4xSGSS.
If not try 2xMSAA 2xSGSS, it's not as good but you should double your low fps.

Turning off 'secondary lights' helps around traffic as their indicators and brake lights will no longer project their coloured light on to surrounding objects... but... you'll also lose yours as well, which makes backing into dark areas even harder.

Reduce the distance in front of you that street lights and beacons etc illuminate their surrounding:
Global config.cfg - uset g_light_distance_factor "0.25" <- Any value between 0.0 to (1.0 Default) - lower = higher fps

Turn off flashing beacons:
Your Profile - config.cfg - uset g_disable_beacons "1" <- Default "0" (off)
1 = Beacons pulse without lighting up their surroundings with coloured light.
2 = Beacons disabled.

Any further help would really require a game log so I can see exactly what settings you use, but really its down to SCS to improve their game performance.

I came to this method because of the mod going paid lmao. But you know what? The dropping down to 2xMSAA 2xSGSS really helped, and the aliasing isn't that bad on it, not nearly flickering as using the in-game AA. Now I can max everything and only drop below 60 on a spaghetti junction at night. Thanks a lot man!

And I agree, I wish SCS would prioritize performance before adding detail, ridiculous that it still uses only 1 core... I might stop the game updates until they actually start optimizing.

@Pit-O-Matic - I've used 2xMSAA 2xSGSS for the past 4 years (since we got this working) and combined with r_sun_shadow_texture_size "8192" really helps with the tree flickering or "6144" if fps drop too low around large groups. Default is 4096.

I have long since stopped updating my old driving pc, steam offline and game version 1.41. Higher versions have rebuilt areas that kill my fps and make for an annoying drive, instead of a pleasant one.

SCS added all the extra details so the view point fly around thing or city intros would look good... but it's a driving game and most of that detail can't be seen whilst driving, but you can certainly feel and see the fps drops in those areas.

Hi I am in the process of upgrading my system for what will be the last time.

I am looking at getting a Dell Alienware M18 R2 with a RTX 4080 GPU and Intel i9 14900HX CPU. I want to couple this with a LG UltraGear 4K Gaming Monitor 27GR93U, 27 inch, 4K, 144Hz 3840x2160 res.
Well that was my wish list! What I am not sure of is how this system will work with ATS/ETS2 both now and in the future post version 1.50 or how to set it up with NPI which I have been using with great results for many years.
Any help, or advice would be most welcome.

Thanks in advance.

@MercDriver - I see you have your hardware answer on the scs forum.

In regard to NPI, let's just hope for 1.50+ scs has finally added proper AA to their games so we don't have to rely on these 3rd party hacks...

You say you've been using NPI for years, I assume its 4xMSAA, and that means a huge performance hit.
So, if you want to see what sort of performance your current hardware has then disable the NPI AA by simply changing in game scaling to 125% or 200% and look at your fps.
Whilst not a nice picture to look at it should give an idea of what fps to expect if the game were to have it's own proper AA enabled.
Set scaling back to 100% after test.

Just installed ATS "1.50 experimental beta". Without NPI the game still doesn't look "great". But with NPI when I hit "drive", all I get is a black screen. Is that the end of NPI? Thanks. :cray:

Thanks for the report.

I'd already updated the first post because I suspected this would happen...
"MSAA works with game versions 1.36 to 1.49 using DX11 only.
Game version 1.50+ has TAA implemented and therefore this MSAA shouldn't be needed any more?"

SCS stated that they've been working on the rendering system and so I'd expect that the 'Antialiasing compatibility (DX1x) hex value' will need to be changed to suit... but that's a lot of guessing / checking / testing, again...

Perhaps it's just a case of making sure all in game AA is disabled?
Or
Ensure you are still using the step 2 file.
Or
SCS haven't quite finished working on TAA and it'll be improved during the beta, but then I'm sure they could have seen how it looked and improved it before releasing it if they thought it needed it...

Anyway, I don't use beta's, so can't help yet, if ever...

Well I think we can close the chapter with v1.50
NPI doens't work anymore I think.

One thing is sure: "Antialiasing compatibility (DX1x) ------------------ '0x80000A7F' " Gives a black screen!

I'd be surprised if it was the end of NPI, after all you can use NPI with MSFS2020 and others that also use TAA! The likely cause is as suggested, the AA compatability hex.
