well, if i set the GPU to anything over 0, the "start streaming" & the "start recording" button no longer work, i think it is a GPU selection, as there are mobos out there with 3 or 4 PCi express ports

Yes the GPU number is to select which GPU to use in case you have more than one.

The first one is always 0, so if you only have one, it will always be 0.

we need someone that knows wtf is going on with OBS Studio to sit down and tell as aswell cos i don't fucking know! Everyone is searching to understand how to use obs studio and more specific to find out what settings to use. And those who created the codes and the software sitting back and typing words in a forum. Just make a video and finish with these nonsense. Do you want me and the other customers to use your software and show it to all of our friends? Yes or no? THEN HELP US TO HELP THEM. Make and video and explain what button does what, what setting does what. Wtf is VFR, CBR, CRF, X264....... Who do you think I am? Aistain? I am not.... Dont even try to desugree. I am right and i know it

ok calm your tits, if you want to use something you read the manuals which are available and all you ask about is explained. learn to read and dont expect everything will be handed on the plate. if you dont want to because you are right, go use Geforce Experience - it was made for people with attitude like yours.
Einstein? well he read lot of manuals

where is this "manual" for obs studio? oh, there is one, just that its out of date, and doesnt have the latest settings info. i bet the manual still refers to it as obs multiplatform...

You should try google, i heard it's pretty neat for finding out about things! Plenty of videos out there about OBS classic and studio.
Also you are NOT a customer, you do not pay for anything, so please tone it down.

Things like that are usually done by the community when it comes to open-source projects, certainly ones that are basically coded by a single person.

Like this for example: https://obsproject.com/forum/resour...ware-studio-multiplatform-help-guide-pdf.365/

yes, this is the manual for it, but it only mentions/shows default x264 settings, does not show nvenc options, only says it depends what codecs are installed in your system.

Even if people have already done their research on these things individually, such as Two-Pass Encoding on wikipedia or other forums, it still doesnt explain whether it is better to use it or not when it comes to OBS and what it means for encoding on the fly like you do with this program.

It's a completely different story if you're taking a video from a camcorder after recording your nephew's birthday, slap it into Sony Vegas or Adobe Premiere, choose Two-Pass Encoding and watch your program run through the encoding phase twice with a smile on your face knowing that the frames between a dark scene and a brightly lit scene will have far less blockyness going on.

But what does this mean for recording gameplay with OBS and NVENC, does it cause less than optimal writing to your hard drive as it records? does it matter? does it even work like the highly successful CBR function you guys have?

I understand this is open source and you guys do this for fun, but some testing and a proper response would be nicer then a "lulwut you're doing it wrong" on the forums.

This sort of thing makes me feel more comfortable going back to the bloated Geforce Experience that causes my webcam to lag during loading screens on a game. ALMOST ;)

You gave the answer to yourself. 2Pass Encoding needs more ressources to your hardware encoder. if you´re using this, the processing will be slower. maybe fast enough for a twitch stream 3000kbps/30fps, but maybe not fast enough for 80000kbps/60fps recording to achieve a completly stuttering free video.
same for the presets: default, high quality, high performance.
you can try this out systematically, starting from best quality(slowest processing, high quality+2pass) to worst quality (fastest processing with high performance preset only).

I dont notice the difference in my testing in both performance and quality, so I'm just leaving it off, who knows if it even works

this is free software. feel free to write a manual or make a video.
if you want other to do so, donate to the project, maybe someone is motivated to do so.

im finde with obs and if you know the basics of x264 parameters you run well with obs.
im doing lets play videos on yt for 8 months now and half of this time im using obs studio.

the only thing i miss now is the lossless mode for nvenc.

Well you don't because NVIDIA didn't expose that option in Geforce Experience. Their NVENC API has that setting though.

Well from what I gather from that is that the high quality presets need less bitrate to achieve the same quality as the high performance presets, 2-pass encoding can further increase the quality. How noticable that quality difference is, no idea.
