Question / Help *SOLVED?*OBS Dropping frames due to rendering lag/stalls

[Maggsi]

OS
Windows 10, fully updated as of 30.08.2017

Specs
CPU: i7 6700k OCd to 4.6Ghz
GPU: Gigabyte G1 GTX 980
RAM: 2x8GB DDR4 3200Mhz
Monitor: 1080p 144Hz Gsync and 3 1080p side monitors

Settings
(should be in the log but anyways)
Encoder: Nvenc (Have tried x264, same Problem)
Bitrate: 4000
Resolution: 1600x900@60FPS

Problem
I'll keep it as short as possible
When recording games like Overwatch (in the log file) but also when streaming my OBS drops frames due to rendering lags/stalls.
my CPU doesn't hit 100% usage, not with Nvenc, Quicksync or x264
my RAM doesn't hit 100% usage
my GPU does hit 100% usage in Games and that is when the FPS start to drop
my Components all stay below 70°C, except the GPU that goes up to 75°C sometimes, so they are not overheating
Since i have a 144Hz Gysnc monitor i don't want to limit my FPS to anything below that and since my GPU is pretty powerful i also wanna use it to its full potential and play on high/highest settings

This problem just started randomly, i cant remember when but its been happening in every game from that point on and i have no idea why - i have disabled every overlay or program running in the background and Game DVR and windows gamemode and stuff like that but that didn't help

I have tried rolling back to OBS Version 19.0.3 and that didn't help either, but with OBS Classic it works without a problem with the same settings but it is no longer being updated and all that so i don't wanna use it.

my friend who has an i7 4790 and a GTX 1060 and only one monitor doesn't have any problems


If any of you have an idea or need any other information i can provide let me know

Thanks!

There you go, can i ask what you are looking for in there?

 

[Harold]

I was looking for the pci-e mode which is where it should be (pci-e x16)

If you're running your games without vsync or some other framerate limiter, you should start doing so, as you're overloading your video card.

I was actually running them without because without vsync i got 10FPS more in some games

BUT I HAVE REALLY GOOD NEWS (at least for me)
I updated the Nvidia Drivers to the ones for the Destiny 2 Beta aaand
it works
when my gpu is at 100% load in afterburner it drops to 59.02FPS for a second but when its at 99% like 99% of the time it works with 60FPS

I have no idea if it was actually the driver update because i restarted after it, but before i did that i disabled every possible windows gaming feature - maybe they just needed a restart?

So yeah, no idea why it works now but i'm really glad it does

Thanks for offering your help Harold!
