A tip to people that are running VR in Assetto Corsa

I was looking around in the ini files and found this setting:
MIP_LOD_BIAS=0 ; GO NEGATIVE (ie. -1) TO SHARP THE IMAGE
You find it here: C:\Program Files (x86)\Steam\steamapps\common\assettocorsa\system\cfg
Open graphics.ini

When the value is set to -1 the picture becomes better ingame. I dont know what it does exactly but I have asked Stefano and hope he answer when he got the time. More people have noticed a difference so its not just imagination.

 

DDS texture files have MIPmaps, which means they contain the same image in several smaller sizes. The objects near to the camera use the texture in the original size, while the others switch to a worse (more blurry) one as the distance increases.
With the bias set to -1 you're forcing the game to use the textures in a bigger step than what they'd normally use.

 

Thanks for the info. I just tried -1 and the in car dials are definitely much clearer/sharper. I tried switching between 0 & -1 and the difference was visible. I also tried 2 (blurred in car) and -3 which makes the in car even clearer but the outside world shimmer. I didn't notice any difference in game performance but -1 & -2 do make the car interior dials more readable.

 

Rigel explained it very well, this is more expanded version from NVidia

 

I guess this begs the question if using the negative load bias under the NVIDIA control panel's Texture filtering - Negative LOD bias Allow, Clamp option will override the cfg file and yield the same result?

 

Ah, shucks.

I've shut my games PC down for the night. This, coupled with IPD adjusters could be what I've been waiting for!

I dont know of I can wait until tomorrow to check this.

 

The setting wont go away. On the other hand, starting up a PC is pretty quick.. Ahh decisions decisions.

 

This setting is no longer working since a couple of years: it was very useful with old sims, but now it doesn't maky any difference anymore. On the nVidia forum there was a hack to make it work again, if I recall correctly.

 

Btw, I got an answer from Stefano earlier but since Rigel posted an explanation i forgot to post it here:

 

Does this hit the FPS in-game?

 

Would imagine yes. What's the point of different mipmaps, than reducing stress on system. Otherwise everything could be always maximum sharpness
E: I stand corrected

 

It increases sharpness but also produces more jaggies. I prefer the default. No performance impact here.

 

Like almost anything else changing the map load as both good and less good effects, it is free and easy to try and decide if it's upside are more important than its down side.
In my case going minus 1 gave me a sharper graphic and a better vision in the distance, and that I like a lot!
I did not notice any negative impact on performance and for me it did not change the "jaggies" , neither did I notice any down side to the quality of what I see. Does not mean it is not there, just that they are not important to me, so I did not notice.

 

tried it and I was getting shimmering in the trees which was very distracting, but cant say for certain if things looked sharper as my IPD isnt the default for the DK2.
I'm going to order some IPD adapters so hopefully I will get better focus and will notice the difference.
On the downside it appears Oculus have removed the lens separation adjustment to be able to match the IPD, so I cant match the camera separation to my eyeballs.... (I knew Narcissist Book buying Oculus was a bad thing!)

 

I had tried it with the DK2 and it just looked more gagged. Will have to try again with the CV1, which I think is not as clear as the DK2. The screen door is reduced but still too obvious. Much more colour and the shadow look much better.
The CV1 reminds me of turning off sweet FX when it was working.
Has anyone heard anything about Sweet FX lately?

 

Shouldnt cv1 be much more clear than dk2? Im starting to think that how much ppd you are able to use will affect the results you get from this setting. Im using 1.5 and for me its a positive improvement. Would be nice if people typed how much ppd they are using and if they like the setting set to -1 or 0.

 

-1 & -2 both make the interiors and dials much sharper for me and the shimmering only become visible outside the car less than -2. I settled on -1 as a compromise for both interior and exterior view.

 

DK2, 1.3 ppd, -1 load map
Improved sharpness of cockpit and increased long distance vision, no ill effects

 

Sorry. Old guy here. PPD is super sample? If so I'm running 1.6 CV1. With the DK2 I could easily run 2.0.

 

Yes. Tell us when you have tried with the CV1, maybe you get a more positive result when you not using that much ppd.
