R9 m290x - Artifacts / Screen Tearing

Trying to play Apex with a R9 m290X.

Have to use Page Up of course.

Game loads fine, but there is constant artifacts and screen tearing. As soon as I finish the first race the game quits.

Have tried messing with various ATI settings and disabling second monitor etc… but I have had no luck removing the issues.

Used drivers from bootcampdrivers.com and it fixed it. Game plays great. Figured I would post this in case anyone comes across it.
