My hardware:

CPU: i9 7900X

RAM: 32GB G.Skill 4133MHz DDR4 (8x4)

GPU: Asus Strix OC GTX 1080Ti

Screens: Acer Predator X34A (UltraWide, 3440x1440), 2x Asus PB278Q (infoscreens, 2560x1440)

Games like PUBG and Overwatch is running "buttery" smooth localy on my PC, but when streaming/recording with OBS the FPS is choppy as hell both on recording and my Twitch stream! I can see that OBS is streaming from 10 to 60 fps (ofc tried 30fps settings also, no diffrence). I have tried "every" possible settings in both bitrate, streamserver location, NVENC/x264 and so on... nothing helps! I have 0% dropped frames and my upload speed is 32Mbps (tried many diffrent twitch stream server locations).
No doubt that my CPU is powerful enough to run both a game (as PUBG/Overwatch) and streaming with OBS at the same time.
I just wonder if there is a "simpel" thing I might have not tried yet before probebly trying other broadcast software? I'm open for suggestions! :)

I have tried to google this kind a problem I'm experiencing and those that have this "mysterious framdropping" in OBS like me seems not to have any working solution to the problem as far as I can tell...

Anybody with a suggestion of what the problem might be?
Try a older Nvidia driver and/or OBS version maybe?

Ingame is all between from 65 to 100 in PUBG and I have locked the FPS to 98 in OW witch is constant at 98.

Try capping at 60 and see if it makes a difference, if you're fluctuating that much it sounds like your GPU is maxing out.

Try setting the process priority higher than the game it's running, mainly in PUBG as it was notorious for causing performance hits on OBS when priority is the same as/lower than the game, regardless of GPU usage.

That actually helped, but it still have some "choppyness" in the frames, but alot less.
On my old rigg with a 6700k it was complete smooth with the NVENC encoder but not on my new rig with the 7900X for some really strange reason. (both NVENC and x264).

The solution for this problem is getting a 16:9 monitor! The choppy fps and everything is running smoothly with no stutter or choppy fps on my stream with a 16:9 (2560x1440 165Hz) monitor!
My 21:9 (Acer Predator X34A, 3440x1440) monitor is a really great gaming monitor, but OBS is obviously hating it! :(
