I do use Nvidia too and have none of these problems. Here are my video settings:
* Use verter cache
* Use shaders
* Use a geometry shader
* Disable ubo
* Enable vao
* Enable saving ge screen
In memory settings I enabled invalid memory access.
Try enabling these and tell us if you still experience these problems.
