Been having issues with some games with the Vega 56 since purchase. Figured the drivers would be a bit of a headache for awhile, but the most recent release has caused many issues. I noticed artifacts while just browsing the web, or Steam, graphics card temperature is in the mid 40s-50s with minimal load. Stellaris is unstable and locks up every time I try to play (known issue for awhile) PUBG crashes every 5 minutes. I've also had issues with web pages blanking out while scrolling through.
I just recently upgraded to a SSD as my system drive and reformatted all my drives when i reinstalled for a fresh start. Been having crashing issues in PUBG since the reformat, and before, but I have noticed it get exceptionally worse since this most recent update.
