focusrite scarlett 2i4 game audio stutter lag

[eliteZEALOT]

I have this problem where the game stutter completly, even when the guy talks. the whole game has an audio lag when my 2i4 is plugged in. but when i relaunch it without it plugged in there is not problem. and i also do not have the cable that is why i try using my 2i4

Hi. I am 2 hours into my journey of trying to get this to work.

Focusrite 2i2.

So far I have been able to remove the stuttering by getting the game running and then turning OFF Exclusive mode inside RB (then restart).

It now works, but with a lot more lag than my Sound Blaster which I am replacing.

My latency is too high so that is the next thing to tackle, but thought I would share the stutter-fix for those who are without hope.

That may be because I had to set in game latency to 7, which helped the stuttering. Will report if that fixes it.

Okay, that's as far as I can take it today.

I am using an original usb RS Cable as input, and the Focusrite as output.

Here are my tips for the focusrite Scarlet 2i2 audio interface:

You MUST load their (Focusrite) drivers. Nothing I tried worked using the generic Windows drivers to power the device. (I could still youtube, media music and other games, but not RS on the generic.)

I used the Focusrite ASIO control panel and was able to use settings:
Sample rate: 48khz and a buffer of 16. I left the control panel open while playing RS.

Exclusive mode set to "off" in RS. (That is what fixed the stutter)

Managed to get the in-game latency setting all the way to 1 and it didn't crash.

Subjective input lag now feels completely tolerable for bass and rhythm guitar. If you are a l333t shredder you might still moan. But really. Who can be THAT l33T!


Edit: Jiggled it around for a few more hours. After reading the internets I adjusted rocksmith.ini with MaxOutputBufferSize=1024.

I now regard it as happily playable.

Here's my Rocksmith.ini :

Slightly off topic:

My system was working fine on the Sound Blaster, but it was outputting a lot of electromagnetic hiss to the big speakers I am playing on. I hoped that spending the $$$$$ on the external interface would fix that.

I'd say its about 50% better, but one can still hear over the speakers whenever the CPU is thinking hard or when the screen card is moving anything white around the screen.
This interference must be somehow going up the USB wire and messing with the insides of the Focusrite.
Any tips on reducing that further would be appreciated.

(i7 Cpu on an X99 motherboard, water cooled but probably a fan or 5 still running inside, currently Nvidia 950 GPU but similar noise with a Titan Black.)

Nice to hear you got it working. Doea your rig, guitar and/or the focusrite use a grounded connection? Could be producing the hiss. Or it's just because it normally doesn't work that way so there will be some interference....

Why try so hard for sub optimal performance? The built in sound on your motherboard will have less latency. If you just have to use the Focusrite for some reason then run analog out from your computer to the inputs of the Focusrite. You want the DAC to happen on the computer for minimal lag.

I don't know why people try so hard for complicated setups that usually don't work that well. The best, no hassle, lowest latency setup is a RealTone cable and your on board sound. You don't need anything else.

I would have LOVED to keep the onboard sound. The PC just produces intolerable levels of electromagnetic interference and on the BIG setup I play on I need to move the "sound making" as far away from the maelstrom as possible. The external interface helped enough in this regard for me to enjoy playing again.


(Since my original post I played for many hours, then my PC died. Why? While messing about to get all this working, I must have bumped the rather old water-cooling system. 1 x Wet GTX Titan black + soggy motherboard do not for good Rocksmith make.) :( I am about to try get the Focusrite working on this laptop.

Yikes. So on the laptop just skip the focusrite. Take the headphone out.

So last year that didn't work.

This year it did. I assume a driver update fixed it.

Focusrite sitting watching me play, waiting for the big PC to get back from repairs.

Thanks dude. You fixed it for me.
