NVIDIA Partners with OBS for GeForce Optimization and RTX Encoder

We saw a glimpse of this at the NVIDIA suite during CES 2019, with a beta version coming out shortly after. NVIDIA and OBS (Open Broadcaster Software) have since brought out the full release of a new OBS Studio, version 23.0.1, that adds improved support for NVIDIA GeForce cards. In particular, their latest and greatest RTX lineup, including the new desktop RTX 2060 as well as the mobile and Max-Q variants, will see an FPS impact drop by as much as 66% according to NVIDIA's internal testing. Some example results are seen below, with games such as Fortnite, PUBG, Call of Duty: Black Ops 4 - Blackout, and Apex Legends seeing a frame rate boost by up to 48% compared to x264 Fast, and 27% compared to x264 Very Fast.

Given this is a result of NVENC, NVIDIA's hardware encoder, in place, older GeForce GPUs (GTX 600-series and newer that support NVENC) will also see some benefits. GeForce RTX GPUs just get to enjoy a bit more- up to 15% more, in fact, in efficiency as far as bitrate consumption for the same graphical fidelity. NVIDIA effectively says that "GeForce RTX GPUs can stream with superior image quality compared to x264 Fast, and on par with x264 Medium", thus putting in a strong case for single-PC gaming and streaming, as opposed to having a dedicated streaming PC. They have even put out a video to go over the enhancements, which will no doubt interest game streamers on the PC platform.

Nvidia says. I've seen raw footage of NVENC 6k encoding vs x264 fast encoding & 6k NVENC's image quality is only sometimes on par with veryfast x264 encoding, and doesn't even compare to Medium. The games I saw, most had severe texture degradation at medium/long distances, somewhat similar to say, DLSS except more pronounced.

For streaming with limited bitrate, NVENC as well as AMD's HEVC are inferior if someone wants to stream in any real capacity. Casually? Sure, go for it if you don't have a CPU capable of 6k x264 fast, but don't expect the stream to look as good as someone using x264, it won't.

What NVEC & HEVC as well, will continue to be good at is high bit-rate game recording, as you truly see limited gains when at about, 30k bitrate NVEC/HVEC, but limited performance degradation.

broadcasting your game is slowly becoming more important than the game itself. I miss the 90's early 00's

Just because others do it, doesn't mean you need to. Let alone watch those streams. Honestly, watching people play a game... feels like poverty to me.when you can play yourself.

sure, but I'm worried stupid trends like these will eventually change the games themselves. Also, there's a considerable amout of dev time going into these useless things that could otherwise be going towards optimizing drivers and other stuff:)

I was about to post broadcasting is becoming the social media of gaming.

At the same time, I wonder whether image quality is really that important for streamers? I mean, sure, you don't want your streaming to gobble up all your bandwidth and your watchers probably don't expect 480p quality. But pixel peeping differences probably don't matter.

Also, Open Broadcasting and NVENC don't jive all that well in my head ;)

I'm going to start a new streaming channel of me* watching streams of other people's streams. I'm going to call it Dirty's self malevolence channel for insomniacs. Send me a PM for more info...

*The role of me will actually be played by a stuffed animal ferret as I'd rather watch fish sleep then someone playing a video game.

I'd bet even that will net some followers. And that's no joke.

Look at all those pay2win mobile titles and how they're practically steered by the whales that play them while the rest of the community requests go unaddressed for a glimpse of what's in store. Then again, it's not like the gaming industry is winning customer care awards as it is.

Say whatever you want about Nvidia's garbage pricing and/or their underhanded anti-consumerism, they're fast in adopting/supporting new tech in gaming. While I can't fault AMD too much since it's apparent that they invested their time and money on Zen, it's always AMD playing catch up these days. Shadowplay, VR support and now ray tracing. Even their Youtube channel is all corporate this and that vs Nvidia's games and hardware partners.

Personally I'm neutral towards streaming but I can't deny a quick recording of exciting gameplay wouldn't be possible without Shadowplay and Relive. Many people use the instant replay feature for example.

Shadowplay is all you need to know about their quality. It's horrendous. It's just nonstop severe pixelation. Meanwhile...relive looks decent (for game streaming) lol.

With social media replacing interaction with living beings ... this is what has replaced the normal spocial construct ... pumped even further by the "look at me , look at me" begging for attention and approval ... "circles of avatars" have replaced "circles of friends"

Hey, are you telling me that super hot blonde with 1,500 "friends" on facebook is just attention whoring and will be trouble if I go out with her? No way!

At least facebook is good for sleuthing. You can just immediately ignore people and move on when you see their profile.
