Looks like something's blocking the game capture from getting an optimal capture hook.

Try Studio portable mode: https://obsproject.com/forum/resources/obs-and-obs-studio-portable-mode-on-windows.359/

Until this error is gone:

Failed to read log file

then try to disable Windows Aero and switch off Studio's Preview. By the way with v-sync ON your game must render not more than 60fps for your monitor and this is normal.

i did all that, here's the log:

the problem still occurs, what i noticed is that the fps gets limited to 30, it's like OBS is forcing 30 FPS

Look, when I tested win7x64 system and OBS Studio v0.15.4 with 'Display Capture' source and integrated video, the most impact on the system causes by Enable desktop composition setting. When Enable desktop composition it turned ON in Windows and OBS Studio Preview enabled, my PC CPU utilization and RAM usage rockets up into the sky:

from ~0% and ~2 056KB (Enable desktop composition is OFF; OBS Studio Preview is ON)
to ~10% and ~100 000KB (Enable desktop composition is ON; OBS Studio Preview is ON)

If I disable OBS Studio Preview it make things even worse:
from ~0% and ~2 024KB (Enable desktop composition is OFF; OBS Studio Preview is ON)
to ~15% and ~900 000KB (Enable desktop composition is ON; OBS Studio Preview is OFF)

RAM usage and CPU utilization is for Desktop Window Manager Session Manager (dwm.exe) process from Task Manager (unfortunately power is set to 'balance' by default as most users do, but CPU always running at 1700MHz and GPU is throttling a bit in all the tests - info by Open Hardware Monitor application). More over, the RAM usage rapidly changes in case of Enable desktop composition it turned ON. It's no good.

That's why I'm asked you to turn off OBS Studio Preview and compare. Turn off Aero and compare. Maybe it is not quite clear, because I mentioned only Aero itself not the desktop composition setting. But... OK nothing to do with it.

Results obtained for AMD E2-1800 APU @ 1700MHz (reported by OBS Studio), 1600x900@60Hz. Win7x64.

Edit: turning OBS Studio Preview ON and OFF has no influence to CPU and RAM if Enable desktop composition is OFF (at least for dwm.exe from Task Manager).

Edit 2: it is not 'Game Capture' test.

Edit 3: for 'Game Capture' and Enable desktop composition is ON, dwm.exe simply eats ~25 068KB RAM and ~3% CPU and has more stuttering (not recording test).

do you have any experience with this error?

No.
But I see that you are using Multi-adapter Compatibility option. Why?

Normal message should look like:
[game-capture: 'Game Capture'] Shared-texture OpenGL capture available
[game-capture: 'Game Capture'] gl shared texture capture successful

if you not using OpenGL renderer in Studio.
