Got it working. Had to manually update a driver and couldn't play much yesterday. I did end up in a night server and experienced no artifacts. However, it couldn't update my HDMI sound drivers which was weird. All's well now! I'll report back if something should change.

That auto detection tool says the drivers are up to date, which is obviously incorrect apparently... I will continue attempts to manually update.

Matt, still getting the issue. Played fine for about 20-30 minutes while it was still light out with no problems... As soon as it was dark however, or when i used the flash light, shit got nuts. I tried the auto detect and it said i was already up to date on graphics drivers. I also installed the latest version of CCC to no avail. Uploading a dxdiag and .RPT in the hopes it will assist you.

Same issue for me. Radeon HD 7770. It says my drivers are up to date as well... Going to update CCC and check back.
