- To adjust VSync and disable Frame Rate Cap, in game navigate to Options > Video > Display. There, you'll find the FPS Cap option, which you can disable.
- For VSync, you can also find the setting within the same Video tab. You can choose between double buffering, triple buffering, but do not have it disabled.

Have you tried this workaround?

I can't believe it's been six months since Patch 8 introduced this issue, and it's still not fixed.
