iRacing Live Streaming with OBS Studio

[@roberth8123]

Excellent video, thank you for putting this together!

[@S1Races]

Glad it was helpful!

[@artmcewen3165]

All very helpful for setting up the software but nothing in interaction with Iracing itself. Particularly getting the wide image from triples centred to a typical 16:9 of the centre(ish) screen.

[@S1Races]

Are you trying to have your stream show all 3 screens? I found it challenging to get a decent output for the viewer due to the stretched aspect ratio of triples which is why I didn’t include it and just stream my centre screen

[@artmcewen3165]

@@S1Races my nvidia set hides the 3 monitors from the desktop so I have a single 5760x1080 display as far as windows is concerned so I can’t just pick the centre physical display. Obviously I don’t want to broadcast in that aspect ratio but the OBS choices didn’t lend itself to that. I finally found it under gaming scene and then playing with the black and checker image areas until I got what I wanted. Also have to remember that add ons like ioverlay are browser windows.

[@S1Races]

@@artmcewen3165 Gotcha, I never tested that scenario as I use native triples so that's great advice for others who get Nvidia / AMD software to just render a single display

i cant find the manage broadcast button even though my obs account is linked to my twitch

[@kyleshepherdmusic]

Hi. Thanks for the great tips. Do you always use a single PC streaming/recording setup? Does it ever cause fps loss in iracing?

[@S1Races]

Yeah I’ve always just raced and streamed from the same pc. I also had the same concerns when I started out but so long as you’re using the hardware encoder in your GPU, I find the impact to fps is minimal. The only time I’ve had issues is when I accidentally had the CPU doing the stream encoding and then that is a big hit to fps

[@gpmotorsport]

My in-game FPS takes a big hit and makes the game a bit laggy just when I launch OBS....not sure what to do...

[@S1Races]

What’s your system specs and monitor? I had the same issue when moving to triple 4K but after killing my overlay app and adjusting graphics a bit I’ve found a balance that allows me to stream and race without stutters. Make sure you have hardware acceleration switched off in any apps you have running if you are GPU bottlenecked

[@louiienation8497]

Is 32GB of ram enough for triple monitors and to stream? Planning on streaming iRacing with my 4070Ti i9-13900k and 32GB of DDR5.

[@S1Races]

Yeah it’s plenty, you’ll be set with that kit. I’m running 32GB, 5800x3d, 4090 and streamings isn’t a bit hit. Just make sure you are using your 4070 hardware to do the stream encoding and not your CPU.

[@louiienation8497]

So how do we prevent the viewers from seeing the OBS tab ?? If I have my triple monitors running all 3 on iRacing, do I need a 4th monitor?

[@S1Races]

What do you mean exactly by the OBS tab and are you just streaming your centre screen? A fourth monitor is only really needed if you don’t want to alt-tab to check on your stream whilst it’s running, otherwise it can just be running in the background

[@Moshins11]

What is the best way to setup live stream with triples when running Nvidia Surround? I know you can't have it record the whole screen. Is the best way to select screen size to 2560x1440 for base and canvas instead of the 7680x1440 and just position the recorded area to the center screen?

[@S1Races]

I haven’t tried this before as I setup triple screens natively by editing the iRacing .ini files. Any reason why you’re choosing to run surround vs native triples?

[@Moshins11]

@@S1Races I have other games that I play that need Surround in order for them to work on triples.

[@HySpeed1]

I had same issue and did what you said, just drug the larger Nvidia surround image to fit in center of display area using display capture.

[@S1Races]

Gotcha, then I can’t think of a better way than what you describe if the triples are running as a single screen in windows

[@jgoringsbnc]

I can't for the life of me figure out how to stream only my center screen. It seems to only want to capture all 3. I was hoping to find the solution to this under your explanation of the sources

[@S1Races]

Are you using nvidia surround or AMD's equivalent? If you are running native triple screens you should be able to choose any monitor from OBS to capture

[@JaggerFinleyRacing]

my obs profile is connected to my twitcxh but im not finding the manage brodcast button what am i doiung wrong

[@S1Races]

Still having the issue? I haven't connected twitch to OBS, just KZbin so I'm not sure but I assume it should work the same way.
