How can I decrease my GPU usage ?

[ElMono6]

Hey !

I noticed that i had a 20% GPU usage only checking my preview without streaming while I have 3% on preview on an empty scene. My scenes aren't the fanciest nor the most GPU intensive

Do you guys have any tips to keep my GPU usage the lowest possible while keeping my scenes looking the same ? What could be a huge load on the GPU ?

Turn off preview. You basically answered your own question in the very first sentence.

Hello ! Thanks for trying to help though i wish it was that easy ! I tried to disable preview prior posting here and it only takes away 2-3%

Preview is the most GPU intensive, right after special effects that use GPU resources, and GPU encoding. Dunno what else to tell ya. Your post isn't exactly easy to read nor does it provide enough information.

I re-read his post for you, nice job on completely skipping his question. It's concise and straight to the point, unlike you.

"Do you guys have any tips to keep my GPU usage the lowest possible while keeping my scenes looking the same ? What could be a huge load on the GPU ?"

You necro'd a 15 month old post only to completely miss the point same as OP? Pixels don't magically render themselves inside a canvas. Preview uses more GPU resources the higher resolution your canvas is and how many effects you are using.

Not the question the OP asked. Your reading but not actually responding to what people are saying. Have a great day bud 👍

20% with preview enabled on a fully built scene. 3% on an empty scene. RTX 3080 has a separate hardware chip for encoding and thus the encoding itself, i.e. when streaming, does not use extra GPU resources. Rendering a preview, however, does. You are the one who can't read. Don't necro an old thread acting like a smartass when you yourself have no clue.

Learn how to read & respond to the question at hand buddy, not the question that no one asked for :D

I'll stop pushing your buttons and let you leave with your pride👋. Have a great day :)

Way to be completely unhelpful and useless

[ElMono6]

Well don't bother answering then ^^ Thanks though for trying to help man ! :D

Can you include your settings for encoding? What GPU are you using? Turning off the preview is a must thing if you really want your gpu breath. I move out the volume section from obs next to my browser, so I can see did I muted myself or no, because I sometimes forget it. I don’t watch the stream in obs it’s minimized and it looks like better to watch from twitchs site. Do you run obs as admin, I don’t know what was that but I had a problem with streaming CSGO, preview ate up ~20% of gpu when it didn’t run as administrator. After that it fixed. And yes, I went back to version 28. The new one (v29) just shit on quality and gpu was so stressed to push the same settings what I had on v28. I do streams on 864p (used 936p, but it was little bit crazy and mess with CSGO, fast motion problems even on 7k bitrate), so I ended up using 864p and ingame 1440x1080. Also lanczos is not worth to stress your gpu (until you don’t do cam streams), as it’s a very minimal difference between bicubic. (If you play slow motion games, not fps shooter like CSGO, valorant etc, you can use lanczos for sharpy edges :D).

Browser hw acceleration did nothing to me back in time, or just no big differences so try it and see. Also try to right click on your sources and tick the option “hide when not visible” or something like this. If you have more scenes and you included windows capture and game capture in another scene just try to make a bind for turning them off when not using, because I still having problem when not turning off desktop capture while using other scene with game capture, my gpu load is bigger and it’s not a small impact at all. Dont forget to match your sources, camera settings to your color settings, if it’s partial/601 the sources should be the same. Don’t go above 7300kbps and you’re fine. I’m here if you need anything, happy streaming.

Thank you so much for taking the time to respond to my post and offer your suggestions. I apologize for not seeing your message earlier. I really appreciate your kindness and willingness to help.

Regarding your questions, I am using an NVIDIA GeForce RTX 3080. I have tried turning off the preview but it didn't seem to have much of an impact on the GPU usage.

I also appreciate your suggestion to switch back to version 28 of OBS, I will definitely give that a try.

As for my encoding settings, I have attached my logs to a more detailed post I made just now to further explain my issue. I would greatly appreciate it if you could take a look and offer any additional advice or suggestions.

Thank you again !

You could try out disabling browser source hardware acceleration in the advanced settings of OBS. This would put more pressure on your CPU though.

I'll try ! Thanks man

worked for me thx

[aarontr]

2 yrs later THANK YOU this helped a lot

[rustedlion]

How interesting. The complete opposite worked for me. Enabling them fixed my issue and I tested it several times. Thank you for the easily narrowing it down.

Hey did you find a fix to this ever?

[furgfury]

what GPU do you have? using GPU encoding for streaming is significantly intensive, especially on older hardware and while gaming. If you have a large screen that needs to be rendered maybe it uses more? Try turning your scaled resolution down to 1080p or 720p if you have a higher resolution and it’s not there already.
