Question / Help New GFX card makes little difference in streams, strange lag with no apparent bottleneck

Windows 10 1809 (64-bit)
OBS Studio 64-bit 23.2.1
Phenom II X6 1100T 3.3GHz
16 GB RAM
Radeon RX 570

I have done most of my streaming through a small, cheap capture device for consoles that seems to work well all things considered. I just upgraded my 7 year old gfx card for a Radeon RX 570 with 8GB. Now I can run games better sans OBS, but with OBS, either attempting to stream or record, things aren't much better. I was using hardware rendering before and after the new card, but when I had issues after the new card's installation I installed this plugin: https://obsproject.com/forum/resour...-framework-encoder-plugin-for-obs-studio.427/

I am not seeing my CPU or GPU (or RAM) max out on task manager and I've tried a few different things. By far my worst lag is appearing on a dual screen game, when I use two monitor captures to stream. https://clips.twitch.tv/DeafAnnoyingUdon4Head is a clip showing the lag, it happens at highest and lowest settings, vsync on or off, and the same at the start and near the end of the game (which matters, the cpu load goes way up as the game goes on). The lag does not sure up in the game for me, only on stream, and existed on streams before changing my card. The log attached is on recording this same game (Supreme Commander: Forged Alliance) and the recordings all showed the same lag.

I'm new to using OBS to get details this precise and all the things I see have me confused. All of my logs report 80+ memory leaks, around 1% frames not rendered due to... lag? But FPS caps, vsync toggling, and graphics settings don't seem to change anything. Am I using other settings poorly? Thanks for any help.

I have found that my problem seems to be based on the monitor capture not working well... the entire lag and stutter back and forth may be from that alone. I have managed to get my second screen to capture with game capture (and that second screen looks great), but I cannot get my first screen in game (or window) capture.

I found this thread that seems to confirm the issue somewhat, for just this game: https://obsproject.com/forum/threads/cant-record-supcom-fa-in-dual-monitor-mode.14402/

It seems that there is no known fix for OBS game capture working properly with this game... but perhaps a fix for screen capture to no be so... bad? Any help would still be appreciated.
