! Trick to Greatly Reduce Input Lag !

[ELK]

In the steam library right click Deep Rock Galactic. Click properties.
Navigate to the Local Files tab.
Click Browse Local Files.
Navigate to \FSD\Saved\Config\WindowsNoEditor\ (or the linux folder if you're on linux)
Open Engine.ini
Add this to the bottom OR just the second line to below [SystemSettings] if it is already present

[SystemSettings]
r.oneframethreadlag=0




EDIT:

The most common responses to this topic have been that this will negatively impact performance & that you do not need a small decrease in input lag in a PvE game.

This will NOT negatively impact your performance I have a post explaining this in detail on page 2 of this thread.

The decrease in input lag is not small it's huge, and the purpose isn't for an advantage it's to make the game more comfortable to play. As all of Linus's tests have shown your skill level depends if you'll be able to notice the change in input lag.

Just wanted to say that I just tried this and it worked great for me. I'm on fullscreen and I have vsync off, but DRG always had noticeably more mouse input lag than pretty much any other FPS I own (not a ton of lag mind you, but enough for me to notice). Thankfully, this fixed it.

Rock and Stone to the OP.

Thank you, I played DRG for way too long and already kind of accepted the input lag (I thought my mouse or the internet connection are the problem). Sometimes a had to click fire 3 or 4 times before the game registred the input. Changing to fullscreen and adding the line made it so much better, wow...

Thank you so much. Mouse movement is much smoother now.

Wow, this worked perfectly. its a night and day difference, thanks man!

Honestly though OP was ful of sht untill I did it. 1 bullet = 1 swarmer is so much easier.

[Fresh Yuuka]

this cant be that easy

[Mussels]

Cant say i noticed input lag in DRG despite being a 165Hz gamer

This took about 10FPS off my average and 99% values for no noticeable difference - they may have fixed this in the DX12 update

This did actually impact my performance pretty hard.
My CPU/GPU are pretty old though, so DDR3, the Bus and Cache are pretty limiting.

Despite OP's claims this will hurt performance if your CPU is at all your limiting factor, which it almost always is in this game. I've tested this myself at multiple points on different hardware and there was always a measurable performance loss.

Tried this and using a controller, it still feels like I'm playing on a cloud game. SUPER laggy, like turn right, let go of joystick, and 1 second later, stops moving. kinda sucks. Was looking forward to this game.

Input lag can be caused by a lot of different things like Vsync for example.

I have zero input lag on my end, so you need to do some troubleshooting.

Also, using a controller prolly isn't helping the issue.

Still relevant in 2023

Using a 3090 at 4K this game can easily hit Vsync, even withotu DLSS - i was seeing upto 100ms 'average PC latency' with no FPS cap, and this tweak now sits that value around 20ms

With an FPS cap and this tweak, sitting around 14-16ms total (Render latency sits around 4ms now)

This reduces the in-game "render ahead" value, which can give you a higher FPS value - but the problem is that when your FPS hits your Vsync limit, you've got queued up frames meaning you're seeing and responding to the past.

DX12 disables Nvidias low latency setting, and for some reason Reflex isn't working as well as it should either.


TL;DR: This reduces the "maximum" FPS, to reduce render latency/input latency.
Not everyone needs it, and an FPS cap is a good alternative.


It's interesting that a year ago i did not have this issue - but with faster hardware, now i do.

[JAJO]

Just tried this with my laptop GTX 1050
Before the tweak: 150ms
After the tweak: 130ms
After disabling VSync; 30ms
I understand the VSync adds latency but I've played for 10+ years with vsync and I have never seen such an increase in input lag with vsync

Works very well, highly recommend

Is this one of them "exploits" I heard so much about? Maybe you should deal with the input lag instead of "cheating" like a true dwarf or smth lol.
