Question / Help Frames missed due to rendering lag.

[TheAdmnFromHell]

Hey guys, I ran into a problem with my AMD Ryzen 7 - 1800x a month or two ago, it started with the PC not being able to stream and game at the same time. Before the problem I was able to stream 1080@60 without too many problems. I figured my freshly applied OC was the cause so put it back to stock but that didn't help, after testing anything and everything I could think up, DDU, reinstall, windows tweaks, replacing system drive, power supply and so on the problem was still there I figured I was one of the lucky that managed to kill a CPU during my first OC in years so I ordered a Threadripper 1920x with a motherboard and a Kraken something AIO.

After everything was set up and working I tried to stream and I still get "frames missed due to render lag" so, I did the same as before, tried tweaks, reinstall's, DDU and so on.
I have got the system running and its fine in windows and or games alone but I can not stream anything other than Battlefield 4 and PUBG on ultra ultra low.

Today while writing this post when I was saving screenshots of stuff I noticed something new, when I'm streaming and watching a replay inside PUBG its laggy, if I let the replay continue and alt tab out of the game the "frames missed due to render lag" goes away. and the stream looks silky smooth. (Playing in windowed mode)


• I've tried so many things that I'm 100% sure I have forgotten to list everything.
Reinstall of Windows. Old and newer versions. From Windows 1607 to Windows 1803 Preview build.
Reinstall of Nvidia Drivers with and without DDU.
Window power plans.
CPU and GPU temps are fine but I re-pasted 3 of the graphics cards (the one I didn't was brand new out of the box)
Replaced Mobo, CPU, Cooler, Memory, M.2 (from Samsung EVO to Intel 760p), 4 x different GTX 1080's, Windows tweaks and power supply.
AMD Threadripper game mode (this made everything waaaay worse)
Game Bar: Off
Game DVR: Off
Game DVR Background Recording: Off
Game Mode: Off
Nvidia Features Off
Different OBS settings. 1080p60, 720p60, 720p30, 480p30, ALL of them generate missed frames due to render lag.
Capping/Limiting FPS / Hz as low as 60

This was working when I had the first AMD system, Ryzen 7 - 1800x, when everything was new.

Rendering lags is basically being GPU limited, not CPU limited. I'm thinking that when you upgraded from an 1800x to a 1920x Threadripper that you increased the GPU usage to the point that the GPU is limited in reserve.

Aside from that, it seems there's some encoding lag in addition to the PUBG session. Can you set the process priority to high on OBS and see if it still happens?

Thank you for taking the time to reply.

I have tried changing process priority before, it get worse the higher I go, but why would the rendering lag go away when I click on a different program? The game is still running and being streamed to Twitch, just without any issues, even on ultra settings. The same issue is on 720p30.

EDIT: The game is running playing a replay of a previous match.

The encoding lag you see in the log is most likely because I'm frantically alt tabbing back and forth to get a screenshot showing the "problem"

Please do two things for me. First, get a clean OBS session log. Open OBS. Let game capture hook the game. Record or stream while playing a round. Then stop the recording/stream. Close OBS. Open OBS and upload the Last Log File (not the Current one). Don't bother alt-tabbing back and forth a lot to check the stats, just play a normal round. The OBS log will have plenty of detailed data.

Second, please download GPU-Z and post a screenshot (the camera button in the program and upload to free image hosting). Make sure that the GTX 1080 is selected in the bottom of the window, and either run a game in the background or run GPU-Z's render test (the blue question mark on the right hand side).

Hey guys, sorry for the late reply. I changed to Server 2016 and the problem is now gone. Not sure what is going on with the Windows 10 installation but it's haunted my 1607 to 1803 build, even after reinstalls...
