Fps stutter on stream but not in game

[thomasshen1]

Hi guys so I'm dual streaming valorant on twitch (with OBS) and Tiktok with (tiktok studio app) while using the obs vertical plugin. Every now and then my twitch stream would have really bad fps stutters (ranging from few seconds to 10+seconds), but my game is perfectly fine and no lag. I have capped the game at 250 fps instead of unlimited, any lower I noticed screen tearing or un-smoothness even tho i know my monitor is only 144hz, turning Vsync solves the tearing but adds quite a bit of input lag. I never had this issue before when i was streaming league/other variety games but somehow when it comes to valorant it stutters every few minutes until I close my tiktok stream. I think it might be GPU overload problem but shouldn't a RTX 4070 be more than sufficient? I opened tasked manager when streaming and OBS was taking up 40%~ GPU usage and the valorant taking up 30-40%, tiktok studio suprisinly only takes 14%~. I had to turn hardware acceleration off because my entire pc would freeze when I alt tab when i had it on, I think alot of people had this problem. For twitch I'm streaming at 1920x1080, 6000 bitrate, P7, Two passes (quater res), for tiktok I already turned it down to 1280x720, same 6000 bitrate.

Please help

The log provided has no active session on it and it's needed. From within the same menu to upload the log file in OBS you can access the folder where the log files are stored. Look for the one when the issue happened and upload it on the analyzer paste the URL here or attach it here using the button bellow.

Check if any of the plugins are causing issues with this. Run OBS is safe mode (look in Help menu) and test it. If it works as intended, check on the plugins discussion section (each one has it's own) to see if someone have had the same issues or ask the dev for support on this.
If the test results on the same issue:
Most time it's better to cap at intervals. So 60, 120, 240
Same thing for the monitor. In your case should be 120hz

Do some tests with the fps ingame first, and if it still happens, change the display monitor rate to 120hz (if it supports it) so everything is in the same interval and test.

Okay there was quiet a few logs but in my folder, I hope any of these are the active sessions logs. I already run obs as admin. I tried both high and low in game settings for valorant but the gpu consumption is about the same as long as I limited the fps to 250, with unlimited it can go to 500+ fps and takes 60~ gpu so i will keep it capped. I think my biggest questions is, is it normal for OBS to take 40% GPU when streaming?
