I'm fairly new to blender and I've come across this issue. My flag with wind physics seems fine when I animate it on my view port using collision physics.

Here's a sample:

Do you have any subdiv modifiers for that flag? If so make sure they have the same amount of subdiv steps on render and viewport. Because the gif you posted seems to have more geometry on it than the last image you posted...
