Add support for non-adaptive VSync
https://www.reddit.com/r/Morrowind/comments/oshoef/why_am_i_having_screen_tearing_with_openmw/
Can reproduce the tearing issue with RTX 3060 and GTX 1050 on both 0.47 and 0.48. Enabling a windowed mode with window border seems to mitigate the issue.
EDIT:
After additional investigation I figured out that OpenMW forces an Adaptive VSync instead of normal one since 0.46. It means that VSync is not applied when current framerate is lesser than the screen refresh rate, what may cause screen tearing. I suggest to turn the VSync checkbox to the combobox. In this case user will be able to switch between an adaptive vsync and non-adaptive one.
