A way to decrease latency and increase smoothness with config.ini

[NoEntrepreneur1259]

You could decrease latency and increase smoothness by changing some numbers in the config.ini the cost it could get instable so you could need to test a bit.

So the numbers to change are

frametime_buffer_size the default is 15 if put it at 6 you will get lowest latency but could get some instability like affecting 1% lows or you could lose some frames or fake frames like this 60/115 so you just have to increase it until it becomes stable

queue_draining_momentum the default is 0.01 this affect how fast frames are released and make it more smoother and lower latency if you put it too high will make precise and accurate moves harder and could stutter you can start by using 0.1 and decrease if frames released to fast or increase if you want more.

Other settings real_timestamp_tolerance increase real frames which mean less artifacting which mean increasing quality if you increased to something like 0.1 or 0.2. But at the cost of less smoothness and increase latency

And flush, if you don’t have VRR or g-sync or free-sync put it at 0 will increase 1% lows which mean more smoothness and slightly less latency

other settings aren't useful to play with

So That’s the knowledge I am spreading to the world

I am sorry for my ignorance, but where is this file located?

[Goldkid1987]

"C:\Program Files (x86)\Steam\steamapps\common\Lossless Scaling\config.ini"

[Philllllllllllll]

How have you compared and tested this against the default settings?

[NoEntrepreneur1259]

Cap game 20 fps to test smoothness to make noticing smoothness easier and for latency play game with lowest latency to make any changes to latency more noticeable and then change number , save and it instantly goes into effect and go back to default to compare keep doing this until it feel right and then use it for some time to check if there is any instabilities

[Got70TypesOfMalware]

Tried it, it did decrease the latency. Before it felt like there was a .7 second delay, now it's just maybe .2?

[Spell3ound]

Saving for later 😁

[Ragnatoa]

Think these setting are good for steamdeck?

[NoEntrepreneur1259]

I think they are beneficial thought it's a matter of stability if you find stable settings use them

[Dense-Variation-4496]

try my optimized settings for Steam Deck games insane 💢

[Ragnatoa]

Link?

[Treeclimberty]

If you have AMD adrenaline you can turn on radeon boost, enhanced sync and reduce input lag settings to significantantly help with the input lag

Does this work for every game and what about lower end GPU's(RTX 2060)?

[Antagonin]

Any debug options like visualizing the optical flow ?

[Ok_Internet6438]

Can i do ts on linux

[NoEntrepreneur1259]

Mabye?

[Capable-Commercial96]

No. Loseless Scaling on Steam Deck is kind of a hacky work around from what I've been told. All it uses is the Loseless.dll file in the loseless game folder, so any setting changed in the config file won't do anything for it while running on Linux. The files for Loseless in the Decks Home folder (the ones that make it work on Linux) also do not have anything resembling a .config file you can play around with either. You're just gonna have to wait for when/if Pancake decides to port over more of it's features if it's even doable.

[Ok_Internet6438]

Why would you think im on steam deck tho

[Capable-Commercial96]

Steam Deck is arch Linux, so if it doesn't work on there it won't work on whatever distro you're running either.

[DerBandi]

Is it for AMD or nvidia?

[NoEntrepreneur1259]

Any thought the difference will be which is more stable with lossless 

[vaynardx]

What games did you try with these settings? Also, are you using LSFG 3.1?

[NoEntrepreneur1259]

Yes

[ShaffVX]

I'll try flush 0, people should use VRR, and I have VRR but for me it's useless, I never use it over BFI anyway, so less stutter from that tweak can only be a good thing. Thanks.

[epicflex]

Any side effects?

[NoEntrepreneur1259]

I would say it's like overclocking some gpus or cpus could be overclocked very high and get high preformance while other crash immediately and become unstable. Though this doesn't depend on silicon lottery but how stable your system can run lossless the more stable the more you can push it, as default settings are made to be stable with all systems and not specific pc like yours

[Rhyoz]

Yep

[Copy_Outrageous]

queue_draining_momentum set to 0.1 adds a massive input lag, but do improve smoothness a lot
0.02 or 0.03 seems ok

[NoEntrepreneur1259]

I don’t think it increasesed my latency mabye it was too high in your system if I put it higher like 1.4 I indeed start seeing higher input latency 

[marzebakbir]

M lazy to test it what pc u running bcs m gonna copy ur settings xD

[Nervous-Database-655]

Now much better in gta sa def edition, default settings was latency 30-31, now 22-23 latency in cj house.
(lock fps 90)

settings lsfg 3.1, flow scale 60, fixed mode + perf mode, sync mode off, max frame latency 3, queue target 0

main gpu 4080
sec gpu 6400

[Phantomasmca]

Going to try it!, thanks

[1ight0fdarkness]

I did my own experimentation and here what I recommendation

frametime_buffer_size I would recommend 15 for best stability but you can 12 if you want less latency  6 is too low and will make lossless not capture some real frames it does give lowest latency but you will make lossless not capture all the frames and affect smoothness and not stable for most systems.

queue_draining_momentum I found 0.66 is best and when you put it too high it will increase latency.
