1. Your videocard model.
2. Your driver version.
3. Have you artefacts like on attached screenshots or not (answer "No, I haven't these glitches" - is very important to know too!).
Yes (5th screenshot only) - Only below 250ft, anything above that altitude is fine
4. Does FXAA to MSAA swithcing solving this issue for you completely?
5. Does driver settings reset to Factory settings with choosing default GAME profile after that helps?
6. If you're using some kind of graphics mods (migoto, re-shade or something) does turning them off helps you?
